Abstract
Introduction
On March 28, 2020, roughly 2 weeks after the beginning of the stay-at-home restrictions imposed across the world to reduce the spread of the COVID-19 pandemic,

The relevance of this apparent consensus about the conditions under which domestic violence increases must not be underestimated, as it can provide the support needed to introduce amendments to the criminal law and the criminal policies applied to prevent that crime. The question is whether the empirical evidence corroborates the reasoning behind that consensus. 2 In that context, someone could object, as one anonymous reviewer of this paper did, that the length of the exposure to the risk of becoming a victim—increased by the fact that the lockdowns forced intimate partners to spend more time together—does not necessarily play a role in the theoretical framework of the routine activities approach. If that was the case, then the lockdowns would not lead to an increase in domestic aggression. 3 We will keep that possibility as an alternative hypothesis, although we have found no traces of it in the literature on the COVID-19 pandemic’s effect on crime. 4 In the meantime, the primary research question of this article is whether the data collected during the first year of the pandemic supports this situational hypothesis or not. We intend to answer that question by focusing on the most extreme form of violence against women and using data from six countries that are treated seldom in the international criminological literature. The reasons for these choices are explained in the following sections.
An Empirical Contribution to the Southernization of Criminology
It has become relatively common to criticize the fact that criminologists focus their research on the so-called
From that perspective, the sample of countries used in this article was drawn first from Latin American nations. It includes five countries—Argentina, Chile, Mexico, Panama, and Paraguay—that have introduced specific legislation on homicides against women and have published monthly statistics on them since at least 2017, which provides a reasonable framework for trend comparisons (see the Data Analysis section). These are all Spanish-speaking countries, which simplifies the comparison with Spain, a European country that also meets the requisites above.
With respect to COVID-19’s effect, the six countries studied are no exception to the deterioration in the quality of life that the pandemic generated around the world. 5 By mid-March 2020, all of them imposed mandatory lockdowns to control the virus’s spread (see Table 1). On the basis of the data available, the limitations of which are known widely (Morris & Reuben, 2020), one can say that Spain, Panama, and Mexico appear to have been affected the most with respect to deaths during 2020, while the figures remained relatively low in Paraguay.
COVID-19 Related Indicators in 2020 in Six Countries.
Femicide, Feminicide, Domestic Homicide, Intimate Partner Homicide, or Female Homicide?
All of the countries under study collect data on femicide, but none defines it in precisely the same way. This comes as no surprise, as a similar diversity characterizes the scientific literature on this crime. In practice, the increasing number of studies on violence against women has led to an increase not only in the terms used to refer to the murder of a woman, but also in the definitions of these terms. In the case of
Table 2 presents the legal definitions applied in each country, together with information on the sanctions foreseen compared to those applied for simple homicides. Table 2 also includes the total number of homicides against women and the number of femicides in 2018, the latest year for which both indicators were available. The reader is asked to keep in mind that this is not a comparative criminal law article, which implies that we will not enter into each definition’s legal subtleties. The goal is to illustrate the main similarities and differences across definitions. It is also worthwhile to mention that from an abstract point of view, legal definitions do not necessarily coincide with the operational definitions used when the data are collected. However, in this concrete study, only the empirical data from Spain correspond to a definition narrower than the legal one (see below).
Legal Definitions of Femicide, Sanctions for Femicide and Simple Homicide, Number (and Rate Per 100,000 Population) of Women Victims of Homicide, and Number of Femicides in Six Countries.
Table 2 shows that Argentina and Spain do not include femicide as a specific offense in their criminal codes (CC), although they foresee an aggravated punishment for the man who kills a woman for “gender-based violence” or “gender-based reasons,” respectively. The remainder of the countries include such an offense, denoted either as femicide (
In any case, Table 2 shows that even the broadest definitions of homicide do not include all cases in which a woman is killed. For example, in Mexico, in 2018, there were 893 femicides among a total of 3,769 women victims of homicide. The latter corresponds to a rate of roughly three women killed per 100,000 inhabitants, which is the highest observed in the sample of countries; 6 logically, femicides are not presented as rates because of the differences in the definitions. It can also be seen in Table 2 that there are major disparities in the prison sentences for femicide. The latter range from up to 15 years in Spain, 20 in Chile, 30 in Panama and Paraguay, 60 in Mexico, to life imprisonment in Argentina.
Finally, one common feature of all of the definitions is that whenever they refer to a former relationship, they do not require the latter to have ended within a limited previous timeframe. Hence, a literal interpretation of these definitions leads to the conclusion that, in the eyes of the law, each relationship ties the persons involved during their lifetime.
Previous Research: The COVID-19 Pandemic as a Natural Experiment
Empirical criminologists perceived the introduction of the lockdowns as the initiation of a natural experiment—“the largest criminological experiment in history” according to Stickle and Felson (2020)—and they focused on their effects on crime trends immediately. The first research results suggested that there was a drop in the bulk of crime that produced an immediate decrease in the European prison population rates (Aebi & Tiago, 2020), although that trend differed according to the type of offense. In particular, property crimes decreased (Halford et al., 2020; Hodgkinson & Andresen, 2020), but there was an increase in commercial burglaries (Hodgkinson & Andresen, 2020), hate crimes against East Asians and care providers (Eisner & Nivette, 2020), and in cybercrime (Buil-Gil et al., 2020). In their global analysis of trends in 27 cities in 23 countries in America, Europe, the Middle East, and Asia, Nivette et al. (2021) found that the lockdowns were related to a 37% drop in urban crime overall. These authors used the stringency index Hale et al. (2021) developed to measure the intensity of the lockdowns and found a negative correlation between the latter and the extent of the drop in urban crime: the tighter the lockdown, the greater the decline in crime. They did not observe a displacement to other offline crimes, but did not have a measure of trends in online crimes (Nivette et al., 2021).
As expected, the leading theoretical framework these studies employed was the The following predictions can be made: Personal victimisations in the public sphere (such as the ones resulting from fights, robberies and thefts in the streets) should decrease, while those in the private sphere (resulting from domestic violence offences) and on the Internet (cybercrimes) should increase. (Aebi & Tiago, 2020, p. 3)
For instance, from that perspective, the lack of guardianship that rendered the premises vulnerable explains the increase in commercial burglaries (Hodgkinson & Andresen, 2020), while the drop in high-volume crimes suggests that the decline in urban mobility reduced the opportunities and increased guardianship in households (Nivette et al., 2021).
Against that background, intimate partner violence (IPV) during the lockdowns received extensive attention from researchers and was even qualified as “a pandemic within a pandemic” (Evans et al., 2020). In general, studies around the world were consistent in finding a moderate increase in the global number of agressions between intimate partners at the time of the lockdowns and, more broadly, throughout the first year of the pandemic (Arenas-Arroyo et al., 2021; Campbell, 2020; Eisner & Nivette, 2020; Evans et al., 2020; Gosangi et al., 2020; Mohler et al., 2020; Piquero et al., 2021). For example, Arenas-Arroyo et al. (2021) studied trends in IPV in Spain through an online survey posted on social media (
Finally, from the beginning of the stay-at-home restrictions, several scholars assumed that femicide would follow the same trend as IPV (Boman & Gallupe, 2020; Kofman & Garfin, 2020; Lund et al., 2020; Weil, 2020).
8
This assumption appears logical as, despite the differences across countries mentioned above, all definitions of femicide include IPH, which constitutes the most extreme form of IPV. In addition, several research reviews—based largely on studies conducted in the United States—nurture the hypothesis of a crescendo from nonlethal to lethal domestic violence, which has inspired many laws around the world and constitute the basis of the predictive tests developed since the 1990s without much success. For example, according to Campbell et al.’s (2007) literature review, “the major risk factor for intimate partner homicide (IPH), no matter if a female or male partner is killed, is prior domestic violence” (p. 246). Spencer and Stith’s (2020) meta-analysis also identified several previous types of domestic violence (
In contrast, the results of a minority of studies have suggested that the perpetrator of a femicide does not have a specific profile but is more like an “ordinary guy” (Dobash et al., 2004), a concept that resonates with that of Hannah Arendt’s (1963/2006)
Within that framework, the first research results from three different countries did not support the hypothesis of an increase in femicides during the first year of the pandemic. For example, Hoehn-Velasco et al. (2021) observed that femicides in Mexico remained stable during the lockdown and even declined in some municipalities; moreover, they found a negative correlation between men’s unemployment and femicides; however, they did not provide a specific explanation for this paradoxical finding. In Peru, Calderon-Anyosa and Kaufman (2021) studied homicide trends from 2017 to 2020 and found that the total number of women victims of homicide declined during the lockdown. They attributed this decline to the increase in the number of police officers patrolling the streets and to the difficulties that perpetrators would have disposing of the corpse. In Turkey, Asik and Nas Ozen (2021) compared trends in IPH during 2020 with those from 2014 to 2019 and found that IPH decreased considerably during the first year of the pandemic. They attributed the decrease to the curfew that accompanied the lockdown, which prevented ex-partners from reaching their victims.

The Stringency Index
To measure the length and intensity of the lockdowns worldwide, Hale et al. (2021) developed the
Control Variable: The Seasonal Distribution of Femicide
Following the publication of the first comprehensive crime statistics in France, Quételet (1833) observed an increase in property offenses in winter coupled with an increase in offenses against persons in the summer. He attributed the latter to the proliferation of people in public spaces, but also to the effects of climate variations on human behavior. The second explanation was later discarded as nonscientific, but the first is a pillar of the routine activities approach (Cohen & Felson, 1979). Hence, as this article compared the number of femicides month by month during several years, it is imperative to use the seasonal distribution of that crime as a control variable.
From that perspective, Figure 1 presents the monthly distribution of femicides in Argentina and Mexico from 2017 to 2019. To obtain a sufficient number of observations, we first added the number of femicides in each month of the three years and then presented their distribution in percentages by month. The choice of the countries is attributable not only to the fact that Argentina is in the Southern Hemisphere and Mexico in the Northern, but also to the fact that, even when the three years are added, none of the other countries reached at least a minimum of ten observations by month, which is usually the minimum number of observations per variable required to conduct reliable regression analyses (Altman, 1990). Overall, in Argentina, the greatest numbers of femicide victims during the years 2017 to 2019 were recorded during the months of December and February. In Mexico, the peaks were recorded in December and July. The common point is December, which in countries with a Christian tradition corresponds to the Christmas season. Compared to other periods of the year, during that season, there are more people in the streets buying presents, there are more meetings of friends and colleagues celebrating the end of the year, and there are more family reunions to celebrate Christmas and the New Year. The difference between both countries is that the second peak takes place in February in Argentina and in July in Mexico, thus coinciding with the summer in the Southern and Northern Hemisphere, respectively. This indicates that the seasonal distribution of femicides coincides partially with the general distribution of crimes against persons which, according to contemporary research around the world, continues to peak during the summer (Carbone-López, 2017). One possible explanation is that both countries use broad definitions of femicide. Nevertheless, even in countries where the definition is narrow and corresponds to IPH, such as in Spain, it has been observed repeatedly—and can be seen in Table 3 and Figure 2—that there are peaks in the summer and near the end of the year holidays, which have been attributed traditionally to the fact that those are seasons in which families spend more time together (Cerezo-Domínguez, 2000). That explanation is also inspired by the routine activities approach (Cohen & Felson, 1979), which entails some overlap—crimes against persons increase because there are more people in the streets during the hot season, while femicides increase because families spend more time together during the summer holidays—and may hide subtler interactions, such as those between former partners.

Femicides in 2020 and stringency index (2020).
The seasonal distribution observed in Figure 1 raises doubts about the pertinence of several criminological theories to explain crimes like femicide. For example, why would strain be greater or self-control lower during the summer? Or why would the labeling effect, the social learning process, or the consequences of a patriarchal society manifest themselves predominantly during that season? In addition, the consistency of the trends observed in Figure 1 illustrates the need to take into account the seasonal distribution of femicides when analyzing the effect of the stay-at-home restrictions on that kind of murder. In particular, as the lockdowns did not last the entire year, the increases or decreases observed could not be attributable to them alone but to the usual seasonal variations in femicide as well.
Data Analysis
We use threshold models to measure whether the number of femicides recorded in each country in 2020 differed significantly from the average number recorded from 2017 to 2019. Threshold models in statistics were developed during the second half of the 20th century and, building on Chamberlayne’s previous work, Bruce (2008, 2012) proposed a modern approach to them in 2008 with a focus on the analysis of crime data. That approach was applied by Maldonado-Guzmán et al. (2020) for the study of trends in property crime in Spain, and it is the one used here.
In the first step, a threshold analysis estimates the expected number of crimes in a given year on the basis of the levels of crime observed in the previous years; in the second step, the analysis compares that expected volume of crime to the one observed in reality; finally, it uses
Concretely, we begin by computing the weighted moving average for 2017 to 2019 by weighting the number of femicides in 2017 by 1, those in 2018 by 2, and those in 2019 by 3. Then, we sum up these weighted values and divide them by the sum of the weights (in this case, by 6):
Thereafter, we compute the standard weighted deviation for 2020 compared to the period 2017 to 2019 (
Finally, we compute the weighted
Findings
Table 3 shows the monthly number of femicide victims from 2017 to 2020 in the six countries under study. The table also presents the weighted average for the years 2017 to 2019, the weighted standard deviation for the year 2020 compared to that average, as well as the
In particular, Paraguay recorded 32 femicides in 2020, compared to a weighted average of 48 between 2017 and 2019 (
On the contrary, Argentina recorded 295 femicides in 2020 compared to a weighted average of 282 between 2017 and 2019 (
This country-by-country analysis highlights the threshold analysis’s importance in estimating the stability or instability of the trends observed. The simple estimation of the percentage change in the number of femicides in 2020 compared to the weighted average for the years 2017 to 2019 produced several extreme values that without the threshold analysis, would have misled the interpretation. In summary, in three countries (Spain, Chile, and Paraguay) there were fewer femicides during 2020 than the mean number for the previous three years, while in the three others (Argentina, Panama, and Mexico) there were more, but the differences were not statistically significant. The distribution of the femicides observed in Panama also highlights the importance of a monthly analysis of their distribution that takes into account the tightness of the lockdowns while keeping the seasonal variation in mind. Figure 2 shows the monthly distribution of femicides compared to the stringency index.
Figure 2 shows that the stringency indices were at their highest in all countries in April and May 2020. This indicates that the lockdowns’ intensity was at their maximum during that time. However, in nearly all countries, these months coincide with those in which the number of femicides was at their lowest level. For example, there were between one and four homicides in Chile, Panama, Paraguay, and Spain during these months. In Mexico, where the definition of femicide is broader, April and May were also the months in which the monthly number of femicides was the lowest in the entire year. Finally, in Argentina, the number of femicides was decreasing during these months, thus following the seasonal distribution of femicides in the Southern Hemisphere, which decrease after the summer. Furthermore, the same trend can be observed in Chile and Paraguay, the other two countries in that hemisphere. Conversely, the peaks in the Northern Hemisphere—represented in this study by Mexico and Spain—also coincide with the seasonal distribution of femicide, which takes place in the summer and around the Christmas season. In summary, the trends in femicide in the six countries under study are unrelated to the intensity of the lockdowns.
Discussion
Contextualisation of the Findings
The main finding of our analyses is that, in Argentina, Chile, Mexico, Panama, Paraguay, and Spain, femicide neither increased during the first year of the coronavirus pandemic nor, in particular, during the months when the lockdowns were tighter. In fact, the monthly distribution of femicides in 2020 did not differ from their seasonal distribution in any given year, which peaks during the summer—January and February in the Southern Hemisphere, represented in this research by Argentina, Chile, and Paraguay; and July and August in the Northern Hemisphere, represented by Mexico and Spain 10 —and during the Christmas season, which in the Southern Hemisphere coincides with the beginning of the summer. This seasonal distribution of femicides was observed from 2017 to 2020 both in countries that use a narrow definition of femicide—Chile and Spain, where the definition corresponds to IPH—and in those that use a broader one—Paraguay, Panama, and Mexico. This indicates that the 2020 lockdowns did not lead to an increase in the number of women murdered by their cohabiting partners or relatives.
It is worth mentioning that the same pattern was observed in Colombia, 11 a country that applies a very broad definition of femicide, but that could not be included in this research because monthly data on femicides are available for 2018, 2019, and 2020, but not for 2017, which was one of the conditions to be part of the sample. In addition, the absence of an increase of femicides during the entire 2020 year coincides with Hoehn-Velasco et al.’s (2021) observations in Mexico, Calderon-Anyosa and Kaufman’s (2021) in Peru—although in that case, the authors studied the more general category of women victims of homicide—Asik and Nas Ozen’s (2021) in Turkey, and the Federal Office of Statistics’ data in Switzerland (Office Fédéral de la Statistique [OFS], 2021).
These empirical results refute the situational hypothesis that, inspired by the routine activities approach (Cohen & Felson, 1979), postulated an increase in femicides during the lockdowns because of the confluence of a potential offender and a suitable victim in a reduced space and for an extended period of time in the absence of a capable guardian. In contrast, a similar situational hypothesis was corroborated with respect to nonlethal
The question then is why was the
Criminal Policy Implications
One factor that may have contributed to the state of affairs described in the previous paragraph is the proliferation of studies that seek to establish the profile of the murderers on the basis of known cases of femicides. This is a relatively inexpensive way to conduct research, as the researcher needs only to have access to the relevant documents—for example, the sentences the courts impose in femicide cases—but the methodological weaknesses of a research design that lacks a control group are known widely. In practice, this may explain in part why the literature reviews and meta-analyses presented in our section on previous research have concluded that prior domestic violence is the main predictor of IPH (see Campbell et al., 2007; Spencer & Stith, 2020).
What can a policymaker do with this kind of information? Let us take the concrete case of Spain where the police recorded, in round numbers, 70,000 offenses of domestic assault in 2017, 72,000 in 2018, and 77,000 in 2019, which led to the identification of 53,000, 55,000, and 59,000 suspected offenders, respectively (Ministerio del Interior [MIR], 2020, pp. 171 and 175). This is the equivalent of the total prison population of Spain, which on 31 December, 2019 was 58,517 inmates (MIR, 2020, p. 334). If, at the beginning of the pandemic, the experts foresaw an increase in IPH during the lockdowns and the best predictor of those is a previous history of domestic violence, should the policymaker order the preventive arrest of some of these suspected offenders? Now that our research has shown that Spain recorded one victim of IPH in April, two in May, and one in June 2020, it is clear that using previous arrests for domestic violence as a predictor of future IPH would result in an outrageous number of false positives, in the sense that 99.99% of the known domestic violent offenders did not become murderers. This corroborates the hypothesis that a crescendo from nonlethal to lethal domestic violence can have its origins only in retrospective studies based on the analysis of the previous records of known murderers and that, in practice, it has no ability to predict IPH properly. Researchers are familiar with this pattern, because it can be observed in many life activities. For example, nearly all hard drug addicts have consumed soft drugs before, but the vast majority of soft drug users do not become hard drugs addicts.
Can we criminologists blame policymakers for applying populist criminal policies or succumbing to ideology when we have not yet provided a valid scientific explanation that could inspire effective crime prevention programs? Babcock et al. (2004) showed the inefficiency of programs based on a feminist framework long ago, and recent meta-analyses corroborated that the “classic BIP [batterer intervention program] that relied solely on a feminist framework, a cognitive-behavioral model, or a mix of the two, is unlikely to provide a meaningful solution to the problem of intimate partner violence” (Wilson et al., 2021, p. 3). Nevertheless, evidence-based practitioners are likely to have a difficult time resisting the pressure of activists—often supported by government officials—to continue such programs as long as there are no realistic and efficient alternatives.
Three Ways Forward
The complexity of the interactions between affection, power, opportunity, and gender highlights the need for a more holistic approach to studying and preventing femicides. We believe that there are three lines of research that, used in combination, can help reach that goal. First, it appears to us that it is time to place the study of femicide in a wider context. In that sense, femicide’s particular dynamics are more evident when studies are based on the analysis of all homicides recorded during one or more years. From that perspective, Wolfgang’s (1958) classic study, and that of Daly and Wilson (1982), based on all homicides recorded in Philadelphia from 1948 to 1952 and in Detroit in 1972, respectively, can shed some light on the stability of femicides that we observed from 2017 to 2020 in the countries that apply a broad definition of that crime. Both studies observed an over-representation of IPH—which was referred to as
In that context, the missing element may well be a
From that perspective, the main criticism of the original version of the routine activities approach is the lack of definition of the
As millions of relationships are broken—and new ones formed—every day around the world, the question becomes why does the vast majority of the former partners go on with their lives, but some aggress against, and even kill their partners? This led us to our second proposal with respect to lines of research. Now that it is clear to scientists that the nature-nurture debate is pointless because human behavior is the result of the combination of both (Pinker, 2002, 2011; Sapolsky, 2017), we consider that it is time to fully include biology and neurosciences as elements of criminologists’ basic training. In that respect, Raine (2014) pointed out that research on domestic violence is based almost exclusively upon a sociological perspective—which blames a patriarchal society that leads men to use power to control their feminine partners—while in fact the rare neuro-criminological studies in that field have shown that some batterers have a reactive aggressive personality, hence suggesting that there may be, at least in some cases, a neurobiological predisposition to battering. In our opinion, Sapolsky (2017) provided the most comprehensive and multidisciplinary view on the interaction between biology and the environment in his book
Finally, Sapolsky (2017) is aware that cultures change throughout time, which leads us to Norbert Elias’s theory of the
Generalizability of the Findings
In the next and final section, we present our conclusions, but before that, we would like to emphasize that the limitations of the data available—which may suffer alterations in the months to come—and our limited sample size affect our results undoubtedly. Hence, our findings cannot be generalized, and we encourage researchers to replicate our study in other countries. 18
Conclusion
The goal of this paper was to test the
The total number of femicides in 2020 was similar to that recorded during each of the three previous years.
The number of femicides did not increase during the months of strict lockdown. Furthermore, in five of the six countries under study, the monthly numbers of femicides in April and/or May 2020 were the lowest in the entire year.
The distribution of femicides during 2020 followed the pattern of the seasonal distribution of femicides in previous years.
This pattern coincides partially with that of violent offenses, which peak during the summer, when there are more social interactions in the public sphere, but also when family members spend more time together.
The definitions of femicide differ considerably across the countries under study. They all include IPH, most include members of the same kin, and two are even broader.
Some countries define femicide as the act of killing a woman because of her gender/sex, but they do not specify the ways in which that reason to kill can be operationalized and proven in a court of justice; at the same time, most countries’ legislation discriminates against men on the basis of their gender/sex, in the sense that they apply a harsher sentence if the perpetrator of the femicide is a man.
Legal sanctions for femicide differ radically across the six countries, ranging from 15 years of imprisonment to life. However, there is no relation between the length of the sentences foreseen in the CC and the number of femicides in each country. This corroborates the notion that imposing the harshest possible sanctions, such as life imprisonment, does not guarantee any deterrent effect. This is a result that refutes the claims made by activists who have been promoting and imposing harsher laws as the solution to reduce femicides.
The results of this research challenge explanations of femicide based on routine activities theory. In these kinds of explanations, the missing element appears to be a punctual event that motivates the murderer to take action. On the basis of the research available, that event could well be the perpetrators’ awareness of the fact that their relationship is over and their partners are moving on with their lives. However, the vast majority of abandoned partners do not aggress against their partners, which shows the limitations of the current explanations of femicide.
This research contributes to a growing literature which shows that criminologists have not found a scientific explanation of femicide yet, leaving the field open for the promulgation of laws guided by ideology instead of evidence-based research.
To improve research on femicide and develop efficient prevention programs, we suggest setting aside research models based on the study of known cases of femicide to establish the profile of the murderers. Instead, we recommend placing the study of femicides in the general context of homicides and crimes against persons to understand their similarities and differences better.
Finally, knowing that human aggression is the result of the combination of inherited and environmental influences on human behavior, we propose a holistic approach that incorporates biology, neurosciences, and psychology, as well as alternative sociological and cultural explanations.
