Abstract
Introduction
The benefits of social cohesion are multifaceted, impacting both the neighbourhood as a whole and its residents. Neighbourhoods with high social cohesion are safer and have more informal social control, political power, self-organisation, disaster resilience and economic stability. For residents, living in a cohesive neighbourhood is associated with a range of positive outcomes such as well-being, social support, a sense of safety, belonging, integration, and opportunities. Hence, local governments and urban policy focus on improving social cohesion in neighbourhoods and direct attention to potential causes of its loss. Technological innovations have always been among the most prominent threats to social cohesion as they are assumed to shift peoples’ attention and action away from their local environment and dissolve local relations and cohesion.
Research on the impact of information and communication technologies on neighbourhoods has a longstanding tradition dating back to before the internet was invented. The early Chicago School analysed the impact of newspapers and focused on the formation of neighbourly interactions and the integration of immigrants (Park, 1922, 1938). Researchers were subsequently concerned with the consequences of radio and TV on community life (Putnam, 2000; Wellman and Leighton, 1979). More recently, with the rise of the internet, smartphones, and social media, it has again been hypothesised that new digital information and communication technologies (DICT) have altered the structure of human communication and communities in a fundamental way (Hampton, 2016). Within debates around the impact of new technology on society, neighbourhoods have always played a significant role, as compared with other foci of interaction, they are communities that emerge primarily from physical proximity. Owing to their limited physical space as a common factor, neighbourhoods lose relevance when new technologies are introduced that enable people to overcome spatial barriers and facilitate contact with like-minded people elsewhere (see the argument of ‘community lost’ in Wellman and Leighton, 1979: 368). Even Durkheim described the impact of industrialisation and the associated technological advances on the social integration of society and the decreasing relevance of the neighbourhood (Durkheim, 1893). These concerns are especially prominent among policymakers as neighbourhoods are assumed to provide weak ties and bridging social capital, which contribute to social mobility within society. Thus, public concerns over the impact of DICT on neighbourhoods may express the loss of the normative idea of a neighbourhood, which fosters social mobility through social mixing (Galster and Friedrichs, 2015).
More interestingly, while pessimistic public debates express fear of a divergence between digital interaction and neighbourhood life, the two academic disciplines that are concerned with the relationships between DICT and neighbourhoods – urban sociology and media and communication studies–, have recently converged around this topic. The ecological metaphors established by the early Chicago School have been used in neighbourhood research as well as in media and communication studies, with the latter evolving through the rapid spread of mass communication (Katz and Hampton, 2016; Wahl-Jorgensen, 2016). Along this line of thinking, ecological metaphors (e.g. media ecology or news ecology) are commonly used to conceptualise an individual’s embeddedness in a media context. Likewise, neighbourhood studies work with socioecological metaphors to conceptualise the social and material aspects of an individual’s physical surroundings. While the advent of the internet was initially perceived as diminishing the significance of the ‘local’, DICT (especially social media services and platforms) reveal a resurgence of locality, with users creating local Facebook groups, engaging in neighbourhood chats on messenger services or using hashtags to add a spatial reference to their posts. This demonstrates how social media ecology is progressively intertwined with the social and spatial dimensions of neighbourhoods and highlights the need for a comprehensive assessment.
Three problems in the field underscore the need for a more systematic review. First, there is no unified understanding or definition of neighbourhood social cohesion, it is a multidimensional concept that is applied in various ways. For example, it is often posited that DICT reduce neighbourhood social relations, but its effect on other dimensions (such as identification or place attachment) remains less clear. Second, the field is characterised by methodological diversity, not only in terms of qualitative and quantitative approaches but also in terms of data and general platform dependencies of research designs (e.g. the recruitment of study participants). Third, all modern communication processes rely on computers, mobile devices and the internet as basic infrastructure. Nevertheless, in the past 20 years, the devices, applications, and social media services that are used to communicate have been evolving constantly. As such, constraints on adoption and user behaviour exist, which are preconditions for any outcome based on DICT use. Taken together, these conceptual, methodological and technological features have an impact on research strategies and the evidence they produce.
The aim of this article is to systematically review empirical studies on DICT, social media and neighbourhood social cohesion published over the past 20 years. We aim to answer the following questions: In what ways do social media and DICT hinder or promote neighbourhood social cohesion? What are the decisive parameters that determine whether DICT promote neighbourhood social cohesion? Do DICT produce social cohesion in places that have low cohesion or promote it in places that already have some level of cohesion? The remainder of the article is organised as follows: First, we discuss the two theoretical concepts that constitute the starting point of our systematic review: neighbourhood social cohesion and DICT. The theoretical background informed our approach to the search, selection and analysis of the empirical studies subjected to our systematic review, which we describe in greater detail in the Methods. The following three sections present the results of the systematic review, discuss the abovementioned problems and answer the research questions. First, we turn to the diverse conceptualisations of social cohesion and provide a categorisation of measures. Second, we describe the different types of DICT that have been investigated in the reviewed studies, highlighting important properties related to neighbourhood social cohesion and social capital. Third, we present the empirical results from the reviewed studies, which show that DICT promote social cohesion through social capital, but not for everyone and not in every neighbourhood. To explain the inequality among neighbourhoods regarding the benefits of DICT, we draw on the results of this review to develop the concept of ‘catalysts of connection’. This work concludes by highlighting empirical and methodological gaps and providing implications for future research.
Theoretical background
Social cohesion and social capital in neighbourhoods
The concepts of social cohesion and social capital can be distinguished by examining differences between various aggregate levels and the individual level, whereby the degree of social cohesion at the aggregate level is a product of the forms and quality of social relations at the individual level. In this sense, social cohesion is an aggregate-level characteristic that describes systems, subsystems or collectives (Chan et al., 2006; Friedkin, 2004; Friedrichs and Jagodzinski, 1999; Schiefer and van der Noll, 2017). One example of such a subsystem is the neighbourhood. According to various conceptualisations, its degree of social cohesion (Forrest and Kearns, 2001; Schiefer and van der Noll, 2017) might be described by different domains, such as the forms and quality of social relations, identification with people and places, shared norms and values, the presence of social order and social control, or the degree of inequality and solidarity among residents (Forrest and Kearns, 2001: 2129). Chan and colleagues defined social cohesion by subjective components, which refer to individual attitudes (e.g. trust, the willingness to cooperate) and objective components, which refer to observable actions (e.g. participation in community meetings, mutual help; Chan et al., 2006). Although their concept is not intended to measure social cohesion at the neighbourhood level, the distinction between attitudes and observable actions is also well suited for the study of neighbourhoods.
Social capital, on the other hand, is either conceptualised as an individual characteristic that determines access to resources through social networks (Bourdieu, 1983; Granovetter, 1973) or a characteristic that can only be attributed to and is produced in collectives (Coleman, 1988; Putnam, 2000). According to Bourdieu, the function of social capital is to provide individuals with the power and ability to access resources by leveraging their networks or relationships. Social capital is thus instrumental for gaining a better position within the social hierarchy. Conceptual confusion arises from the fact that social capital emerges through social relations and cannot be an individual characteristic, such as economic capital, age or education. Although often measured as an individual aspect (e.g. the number of acquaintances), it captures a relational aspect as well. Coleman defined social capital as the resources embedded in social networks (such as trust, norms, and social connections) that individuals can draw upon to achieve their goals. He argued that social capital is not owned by individuals but is a collective property of a social group or community. According to Coleman, social capital facilitates cooperation, mutual support and the efficient functioning of communities (Coleman, 1988), which resonates with the social cohesion domains described by Forrest and Kearns (2001: 2129).
Compared with other types of collectives (e.g. families, companies), the unique specificity of the neighbourhood is its spatial boundary. Neighbourhoods ‘place’ individuals in physical proximity to each other such that other characteristics (e.g. income, ethnicity) might not constitute a collective. Owing to individuals’ economic capital, preferences and the housing market, this placement is sometimes more deliberate, results in social inequality within and between neighbourhoods, affects identification, and ultimately shapes opportunities for the formation of local social capital.
How DICT change communication
To understand the impact of DICT on neighbourhood social cohesion, we first need to understand how DICT are defined and what features are expected to have an impact on neighbourhood relations. Media and communication scholars emphasise that the specific technological features of DICT create networked publics that alter the structure of communication and social relations. Social networking sites play a decisive role in providing these networked publics, as they construct (semi-)publics within a bounded system and enable users to articulate connections to other users (boyd, 2010). Once established, ties have the potential to become enduring communication channels, keeping people in ‘persistent contact’ (Hampton, 2016: 103). Although a variety of messenger services and social media sites have emerged in recent years since the email list was created (boyd and Ellison, 2007), they all share the same functions. Social networking sites typically provide means for one-to-many communication that enable each user to ‘broadcast’ information to peers via messages in open or closed group chats, comments or postings on personal ‘walls’ that are visible to all other users of the system. Although the networked publics have much in common with other ‘analogue’ publics (e.g. ‘third places’ in Oldenburg, 1999 or ‘micropublics’ in Amin, 2002), the fact that they emerge due to the intersection of people and technology brings about specific features. The automatic recording of online expressions is ideal for asynchronous communication and allows users to search older messages (persistence and searchability, Boyd, 2010). Online content can be easily duplicated, forwarded, shared and distributed to other users. Through these features, its potential visibility is very high, depending on the audience’s interactions with the content (scalability and replicability, boyd, 2010). A result of this continuous, asynchronous exchange of content within networked publics is what Hampton termed ‘pervasive awareness’– an affordance of the ‘ambient nature of digital communication technologies’ (Hampton, 2016: 111) that provides continuous flows of information on the activities of social ties.
Although DICT and networked publics appear to be independent of physical space in the first place, the actual usage of social media platforms and messenger services reveals the high relevance of spatial references. With respect to their impact on neighbourhood social cohesion and social capital, a range of questions remain: in which neighbourhoods are DICT used? Where do they affect social cohesion and social capital? Which features of DICT play a role in neighbourhoods? Which dimensions of social cohesion are affected? How do DICT impact individual and collective social capital in neighbourhoods?
Method
We conducted a systematic review of 52 quantitative and qualitative empirical studies (Figure 1). We considered studies that were indexed in the Web of Science (Scopus) 1 in September 2022 and published no earlier than 2001. The studies had to be published in English and in peer-reviewed journals. Our target category contains three dimensions that the studies had to cover to be included in further analyses: (1) the use of DICT; (2) a small spatial scale (the neighbourhood level or small municipalities of similar size); and (3) at least one aspect of social cohesion or social capital.

Research design for systematic literature review.
As a first step, we performed a complex search string on Web of Science (Scopus) based on the keyword collection of the three dimensions combined with the term ‘digital*’ (in all its forms, indicated by an asterisk). 2 All the keywords used are shown in the online appendix. This process yielded a list of 812 articles. After checking the formal and thematic fit (by screening the titles and abstracts) in the second and third steps, 31 publications that met our criteria and were therefore retained in the corpus were identified. Decisions on content suitability were made by a team of three scientists to avoid any possible bias. In the fourth step, an additional 21 suitable studies were identified through backwards citation chaining and included in the analysis. After this search and filtering process, a total of 52 studies were identified and used for further analysis.
The methodology used for the qualitative content analysis was based on the steps outlined by Miles and Huberman (1994). The first step involved sequentially reviewing and coding relevant works in a within-case analysis. The second step involved comparing the findings across studies in a cross-case analysis to identify commonalities and differences. The 52 articles were thoroughly reviewed using this methodology. In the first step, the studies were categorised as quantitative, qualitative, or mixed method to account for their respective epistemological and methodological foundations. The corresponding text segments and tables were categorised on the basis of our research questions and aims, the definition and measurement of social cohesion and social capital, the methodology, the research area and the results. MaxQDA24 software was used for this categorisation. In the next step, a spreadsheet was created including the bibliographic details and a synopsis of the condensed categorised segments (Supplemental Table 2 in the online appendix). The cross-case analysis was subsequently conducted using this table.
Approaches to measure social cohesion in neighbourhood
In research practice, the reviewed studies employ measures for (1) identification and perceptions; (2) social interactions, networks, and resources; and (3) civic participation (Table 1). The concepts and measures in the first category refer to feelings, attitudes and perceptions. Respective items focus on feelings of belonging (Mesch and Talmud, 2010), place attachment (Jung and Kim, 2021), beliefs about community life and the engagement of others (e.g. Gibbons, 2020; Kearns and Whitley, 2019) and perceptions of social cohesion (e.g. Schreurs et al., 2020). The measures in the second category ask about objective behaviour, whereby the quantity of interaction is either operationalised by its frequency or by the number of people the respondent interacts with. Some studies further qualify forms of interactions such as interpersonal discussions (e.g. Kim et al., 2019); helping, borrowing or lending items and activities (e.g. Mesch and Talmud, 2010); or bridging ties (e.g. Ognyanova et al., 2013). Other studies survey personal networks, network diversity and access to local resources (e.g. Hampton, 2007; Hampton et al., 2011; Tseng and Hsieh, 2015). It is important to distinguish between neighbourhood-related perceptions and feelings as measured in the first category and actions as measured in the second category, as they may lead to different outcomes; even invisible ties contribute to feelings of belonging (Felder, 2020). The third category includes measures of civic engagement, which include taking action for the community (e.g. cleaning the street, reporting problems) and different degrees of involvement in neighbourhood organisations (e.g. sports clubs, youth groups, religious groups, charity and social clubs, crime prevention groups and local politics). Civic engagement and participation in local organisations reflect a form of orientation towards a common good, as actions taken in such organisations produce goods for their members and the neighbourhood. In summary, the three categories reflect approaches to measure various aspects of social cohesion.
Overview of measures.
DICT and social media platforms analysed
The reviewed publications investigate different types of DICT, ranging from mailing lists in early studies (since 2001) to the effects of social media platforms and messenger services in more recent studies (since 2010). With respect to the place-related effects of technologies, it is important to understand how spatial references come into play. On social platforms such as Facebook, Instagram or X/Twitter, users are required to actively construct localised communities. Spatial references must be actively included
Conversely, commercial neighbourhood platforms and localised DICT have a spatial reference built in
Email and messenger services, which are commonly used for neighbourly interactions, operate differently, as users must have other users’ contact information to initiate communication. In the reviewed studies, communication primarily consists of emails sent through curated lists (Hampton and Wellman, 2003) or in group chats created in messenger services such as WhatsApp (Schreurs et al., 2020; van Steden and Mehlbaum, 2022). In contrast to social platforms, email and messaging services require their users to have contact information of others to initiate communication. Consequently, the outreach, scale, and accessibility of neighbourhood networks created through messenger services or email lists are more restricted because they are based on existing ties. On the other hand, this may lead to a more private setting for communication (Baborska-Narozny et al., 2017; Kotus and Hławka, 2010). These distinctions underscore a critical aspect of communication technologies’ relationship to neighbourhood social cohesion, highlighting how spatial references embedded in platform design may shape social capital formation.
Empirical findings
Do DICT promote neighbourhood social cohesion?
As for the relationships between DICT and social cohesion, the results of the reviewed quantitative studies support the hypothesis that DICT use promotes various aspects of neighbourhood social cohesion. The use of DICT is tied to a range of outcomes at the individual level: increased neighbourhood belonging, community perceptions, and place attachment (Capece and Costa, 2013; Choi et al., 2021; De Meulenaere et al., 2021b; Gibbons, 2020; Kim et al., 2019; Mesch and Talmud, 2010; Nah et al., 2022; Shim, 2013); talking more frequently about problems with neighbours (Ognyanova et al., 2013); larger networks and a greater number of weak ties (Hampton, 2007); increased collective efficacy (Capece and Costa, 2013; Choi et al., 2021; Kim et al., 2019; Nah et al., 2022); improved access to resources and support from neighbours (Cabitza et al., 2016; De Meulenaere et al., 2021a; Gibbons, 2020; Hampton, 2003; Nah et al., 2022; Reisdorf et al., 2022); intergroup interactions (Ognyanova et al., 2013); bonding and bridging social capital (Tiwari et al., 2019); higher community satisfaction (Cabitza et al., 2016; Dutta-Bergman, 2005; Shim, 2013); greater community participation and membership in organisations (Capece and Costa, 2013; Dutta-Bergman, 2005; Jung and Kim, 2021; Kim et al., 2019; Liu et al., 2018; Matei and Ball-Rokeach, 2003; Mesch and Talmud, 2010; Tseng and Hsieh, 2015); and civic participation in neighbourhood events (Johnson and Halegoua, 2014; Liu et al., 2018; Nah et al., 2022; Nah and Yamamoto, 2017; Ognyanova et al., 2013).
While most studies indicate a positive relationship between DICT use and diverse aspects of neighbourhood social cohesion, only a few make causal claims about its direction. On the basis of two panel analyses of the Blacksburg Electronic Village, Kavanaugh and Patterson showed that the longer people are connected to the internet, the more they use it to build social capital, but community attachment increases for only a subset of respondents who were already involved in the community before the new communication technology was implemented (Kavanaugh and Patterson, 2001). By introducing a mailing list to three neighbourhoods, Hampton demonstrated that the adoption of DICT is greater in a suburban neighbourhood with high residential stability, the presence of children and a strong sense of community (Hampton, 2007), which are characteristics that favour the formation of local connections. Both studies concluded that for DICT to have a positive effect on social cohesion, there must be pre-existing social ties from which the online community is evolving.
Qualitative studies further elaborate on the processual character of on- and offline communication flows and their importance for promoting social cohesion. Conversations initiated within an online group may transition to private settings (one-to-one communication) where they continue digitally or result in face-to-face meetings in the analogue realm (Breek et al., 2018). Frequently, digital events or gatherings are organised online and then materialise within the neighbourhood. Simultaneously, information from the analogue sphere is integrated into digital networks. Through digital media, these different place-making activities are documented online, where they are visible even to residents not directly involved in them (Breek et al., 2021). Ideally, this fosters a reciprocal flow of information where digital communication does not replace interactions in the analogue world but rather complements and enhances them, making them more efficient. Hampton and Wellmann’s ethnographic observations in Netville suggest that new offline practices, such as sitting on the terrace in front of one’s home, might be established through online interactions within a smaller group and then carried over to the neighbourhood, where they are imitated by others (Hampton and Wellman, 2003: 301).
These findings are further supported by cross-sectional studies that are theoretically grounded in communication infrastructure theory. This theory posits a positive relationship between connection to a local storytelling network and civic engagement. Local storytelling networks have three components, the so-called storytelling agents: interpersonal discussions with neighbours; geo-ethnic media; and neighbourhood organisations. According to early studies, the internet promotes civic engagement (Jung et al., 2013) as it improves connections with neighbourhood organisations and local media. Later studies either incorporated social media into the measurement of integrated connectedness to the storytelling network (ICSN) or elucidated the interaction effects between ICSN and social media use. With respect to different dimensions of neighbourhood social cohesion, studies have produced mixed findings. While Kim and colleagues found overall positive correlations for informal social control, social cohesion, identification and participation and social media use (Kim et al., 2019), Choi et al. found expressive social media use to be positively related only to neighbourhood belonging (Choi et al., 2021; Jung and Kim, 2021). These divergent results may be due to differences in the operationalisation of social media use. While Kim and colleagues measured overall social media dependency (everyday dependency on the most preferred social networking service), Choi and colleagues used social media news expression (the frequency of sharing news and opinions via social media) and therefore focused on a specific form of use.
Finally, some studies contradict the finding of positive relationships between DICT and social cohesion. DICT use does not per se result in higher levels of social interaction or identification with the local community, especially in deprived neighbourhoods. Rather, it depends on how residents use the internet and social media (Hatuka et al., 2021; Kearns and Whitley, 2019). A study based on disadvantaged neighbourhoods in Detroit revealed a positive relationship between variety of use and social capital, but the use of social media is not directly related to access to resources (Reisdorf et al., 2022). In a study conducted across the US, Hampton and colleagues reported that people who use DICT have more diverse networks and that DICT indirectly supports participation in different community settings, including neighbourhoods. Only one activity was found to reduce acquaintances in the neighbourhood: the use of social networking services (Hampton et al., 2011). A qualitative study carried out in a disadvantaged area of Stockholm compared the effects of a newly implemented local communication platform and an IT café and concluded that only the latter had a positive effect on local social contacts since it also served as a meeting place for face-to-face interactions (Ferlander and Timms, 2007). Authors from the Netherlands found a lower sense of community among members of a neighbourhood crime prevention group on WhatsApp but greater previous experience with neighbourhood participation in other domains (Schreurs et al., 2020). The findings indicate that the positive effect of DICT use in deprived neighbourhoods depends on opportunities for face-to-face interactions that build social capital and residents’ prior experiences and perceptions of the local community.
For whom do DICT support neighbourhood social cohesion?
Socioeconomic status, age, ethnicity and migration background have important implications for the relationship between DICT and social cohesion. With respect to education and income, the results are straightforward: almost every study that controlled for education or income found a positive relationship with DICT use for neighbourhood community connections. This is not surprising given that education and wealth predict both having better access to DICT and living in neighbourhoods with greater levels of social cohesion. Internet access and its variety diminish with age, presenting greater challenges for older populations (Kearns and Whitley, 2019; Reisdorf et al., 2022). Quan-Haase et al. (2017) reported that younger participants were more likely to rely on digital media. In particular, older people use digital media less for exchanges of support than younger people do. Nevertheless, older adults maintain their social ties with family and friends by using an array of digital media in addition to the telephone; they especially use email to keep in touch with friends. As for the use of DICT, the relationship with age seems to depend on the actual platform and activity: whereas community-oriented online participation is more prevalent among younger groups (Nah and Yamamoto, 2017; Ognyanova et al., 2013), the use of specific online groups and social networks for neighbourhoods partially increases with age (Capece and Costa, 2013; De Meulenaere et al., 2021a, 2021b; Shim, 2013).
The extent to which DICT affect neighbourhood social cohesion varies among ethnic communities and is influenced by factors such as the duration of residency, language proficiency, individual media ecology and the significance of connections within one’s own ethnic group. With increasing length of stay, immigrants are better connected to the local communication infrastructure. In part, this is explained by decreasing language barriers and, in some cases, by establishing communication infrastructures such as geo-ethnic news websites or social media channels that support intra-ethnic contacts within the neighbourhood (An and Mendiola-Smith, 2018; Liu et al., 2018; Matei and Ball-Rokeach, 2001; Ognyanova et al., 2013). Moreover, the existing local news and media infrastructure within ethnically diverse neighbourhoods tends to attract readers and contributors among the native population with high DICT proficiency and community involvement (Chen et al., 2012). This results in a self-reinforcing effect, as the content on the platform promotes local narratives that reflect only the perspectives of dominant user groups (Bronsvoort and Uitermark, 2022).
The role of DICT in promoting neighbourhood social cohesion differs across socioeconomic and demographic factors. For younger, more educated, and affluent groups, DICT is a strong facilitator of community connection, which is attributable to their greater technological access and residence in more cohesive neighbourhoods. Older adults engage less comprehensively with DICT due to access barriers but remain connected through more traditional communication technologies. In contrast, the impact of DICT within ethnic minority communities is nuanced and positively related to longer residency and language assimilation, although the content of local DICT often predominantly reflects the perspectives of the most technologically adept users.
This review also reveals shortcomings in current study designs. There is a high degree of geographic inequality regarding the study areas, with almost all studies conducted in Western Europe or North America, while only a few studies are from the Global East and none from the Global South. There is a lack of more recent longitudinal studies involving DICTs such as social media platforms or messenger groups. Moreover, most studies focus on only one DICT (e.g. Facebook or X/Twitter), while at present, communication habits typically involve several forms of DICT, with their features being increasingly tailored to their users’ communication behaviour. While qualitative studies provide a nuanced understanding of online content and its impact on residents, most quantitative studies fail to account for the complexities inherent in online content; instead, they rely on a simplistic dichotomy of use versus non-use.
Conceptualising ‘catalysts of connection’
Empirical findings indicate that DICT increase social cohesion in neighbourhoods where social capital is high. In developing a conceptual framework (Figure 2), we employ the metaphor of ‘catalysis’ from the field of chemistry for its illustrative power rather than to imply a natural or inherent process. Just as a chemical catalyst facilitates and accelerates a reaction without being consumed by it, DICT interact with and accelerate the ‘reactive’ relationship between existing social capital and various domains of social cohesion, such as an increased sense of security, community attachment, social order or mutual support. According to Coleman (1988), these outcomes emerge from social relations and communication, and as DICT facilitate and enhance communication, the respective outcomes are also catalysed. In general, this acceleration is based on the affordances and characteristics of DICT and the networked public (boyd, 2010; Hampton, 2016). In the specific context of the neighbourhood, a spatial reference must be established either in user communication (

Conceptualisation of the catalysing effect of DICT on social capital and related outcomes.
Two properties of DICT are particularly important for determining how catalysis works: (1) the characteristics of the technology and the platform on which a networked public is emerging; and (2) the content and users with whom networking takes place. We assume that analogous to the functioning of a catalyst in chemistry, the adjustment of these two features determines whether and to what extent the ‘reaction’ is catalysed.
In addition to the finding that neighbourhoods with high social capital are more likely to use DICT, two focal points of social capital in neighbourhoods stand out from the analysis of the findings: neighbourhood organisations (collective social capital) and highly networked individuals (individual social capital), whose outcomes are particularly catalysed by DICT.
Implications for future research
On the basis of our theoretical concept, we expect neighbourhoods low in social capital to largely miss out on the beneficial outcomes of DICT. The potential explanation for this hypothesis is multifaceted and calls for further research that centres on the effects of DICT in neighbourhoods that lack social capital, are economically disadvantaged and ethnically mixed. Future research may focus on these types of neighbourhoods for several reasons. First, a spatial disadvantage results from unequal connection and signal quality as the provision is based on a market mechanism, and areas that seem least profitable to providers will be worst equipped (Mossberger et al., 2021). Second, people with low income are found to have a different motivation to use DICT, less access and device diversity, and different digital skills, which are related to less beneficial outcomes (Helsper, 2021; van Deursen and van Dijk, 2018). Third, technologies and platforms explicitly designed to improve neighbourhood relations and mutual assistance are least used in economically disadvantaged and ethnically heterogeneous neighbourhoods, as the intention to use such DICT is preceded by a positive perception of neighbourhood social cohesion and pre-existing social capital. In addition, for the platform owning companies, it might appear less profitable to operate in areas with fewer users and fewer online interactions. In summary, we hypothesise that these neighbourhoods are less likely to reap the benefits of the digital era, which will result in increased socio-spatial inequality between neighbourhoods. We call for more empirical research challenging this hypothesis.
Another important aspect that needs further investigation is the actual content created and consumed in neighbourhood-related DICT use. According to our concept, we assume that the quality of content determines the moderating effect of DICT use. In fact, there may be cases in which negative content limits the catalysing effect of DICT or reverses it, leading to a reduction in social capital-based outcomes. This could be the case in situations of conflict and hate speech in online neighbourhood groups or any form of territorial stigma that is transmitted through digital communication (e.g. Butler et al., 2018). What types of online content affect social capital-related outcomes? Does the type of content in local networked publics vary depending on the neighbourhood? Is there a heterogeneous effect of DICT, depending on the socioeconomic status and ethnic diversity of the neighbourhood? Future research designs comparing the catalysing effects of DICT across different neighbourhoods might also compare the effects of different technologies and platforms within the same neighbourhood to better understand how platform dependencies and affordances shape online neighbourhood communication and local social capital.
Both gaps can be investigated by comparative research designs across various neighbourhoods and platforms. Beyond the call for more multi-level studies, which has been expressed before (Friedland, 2016; Hampton et al., 2011), we see an urgent need for more longitudinal research. Current longitudinal studies, while pioneering, are confined to mailing lists and forums, forms of DICT that became outdated with the rise of social media platforms and messenger services. Hence, there is a notable gap in research investigating the causal direction of the relationship between modern DICT and neighbourhood social capital. Qualitative studies draw attention to the nuanced interplay between online and offline networks, suggesting that the use of DICT may enhance community perceptions and identification, potentially leading to increased ‘real-world’ interactions. Understanding this phenomenon is crucial as social capital presents various perceptions that may affect, or actions that may reflect, community engagement. Future research should dissect whether a particular form of social capital acts as a prerequisite or whether a synthesis of multiple forms is essential for leveraging the effect of DICT on neighbourhood cohesion.
