Case Explained: The ecological impact of the COVID-19 pandemic on crime trends in Kerman Province of Iran – Legal Perspective

In the initial year of the COVID-19 pandemic, there was an average increase of 11% in the incidence rate ratio (IRR) of conflicts compared to the previous three years. Although conflict rates declined in 2019 relative to 2018, a resurgence was noted in 2020, with men’s conflict rates consistently exceeding those of women throughout this period.

Homicide rates

Homicide rates demonstrated a downward trend from 2017 until 2019, followed by an initial increase at the onset of the pandemic. Despite this initial rise, a significant decline in homicide rates occurred throughout the pandemic period. Notably, the monthly count of homicides at the end of 2020 surpassed projections based on pre-pandemic data, highlighting critical changes post-pandemic onset.

Comparative analysis of existing literature

Comparative studies from various regions underscore the complexity of the pandemic’s impact on crime rates. For instance, the effects on theft rates exhibited significant variability across different communities; while some areas experienced notable fluctuations, others maintained stable rates^{5,7,8,9,10,11,12,13,14,15}. In Bangladesh, traditional crimes, such as vehicle theft and illegal arms dealing, saw little change post-pandemic, whereas illegal drug trafficking surged⁴¹. Conversely, Indonesia reported an overall decline in crime rates during the same period⁴². Similarly, in India, economically motivated crimes increased, while violent crimes largely remained unchanged⁴³. Specific studies indicated a surge in various forms of violence and conflict in multiple countries^{7,15,19,20,21,22}. Initial reports highlighted an increase in domestic violence; however, this trend eventually declined in certain regions⁴⁴. Conversely, other types of offenses, including public harassment of women, assaults, sexual offenses, and drug-related crimes, exhibited declines in specific areas^11,12,13. Moreover, another study showed a notable decrease in theft and homicide rates across various cities globally¹⁶. Additionally, existing literature indicates that some regions experienced increases in homicide rates^23,24, while others reported no significant changes or even reductions^{9,25,26,27,28,29}. To understand the fluctuations in crime rates during the pandemic, it is necessary to consider the underlying factors at play.

Factors influencing crime rates

Numerous studies have documented reductions in property crime during the pandemic, particularly in crimes dependent on physical proximity, aligning with our findings. Factors such as increased home confinement, heightened awareness of personal belongings, and diminished opportunities for criminal activities likely contributed to this decline^2,5,16. Additionally, the closure of businesses and public spaces further reduced potential theft targets, while social distancing measures may have enhanced urban oversight. The decline in vehicle theft and shoplifting could be linked to fewer interactions among individuals outside their homes^16,45.

Despite the reductions in theft rates, the pandemic has generated significant socio-economic challenges, including rising unemployment, educational disruptions, reduced GDP, and increased public health risks⁴⁶. These economic strains can adversely affect mental health, potentially leading to behaviors that contribute to crime⁴⁷. Although a theoretical link exists between rising theft rates and issues such as hunger and poverty, further empirical investigation is needed to substantiate this connection⁷. Previous studies have indicated correlations between unemployment and property crimes^48,49, yet establishing direct causation is critical for effective policy formulation.

Conflicts are influenced by multitude factors, including poverty, unemployment, inflation, and the overall socio-economic landscape⁵⁰. The pandemic has significantly impacted mental health, which may correlate with changes in crime rates^51,52.The restrictions imposed during this period have heightened stress and mental burdens due to concerns about safety, welfare, and financial stability, which could contribute to increasing tensions within households¹⁹. Extended close contact in restricted environments, particularly during lockdowns, may create various negative pressures and emotional responses, potentially leading to conflicts between individuals⁵.

However, the observed decrease in domestic violence reports may not accurately reflect the reality of the situation, as victims may avoid seeking help due to fears of monitoring by perpetrators⁴⁴. Additionally, the decline in conflicts might relate to changes in daily routines, such as reduced interactions in urban settings⁴⁵. Some individuals may have avoided contacting police due to health concerns related to illness transmission, resulting in unrecorded disputes. Furthermore, the closure of courts and dispute resolution centers may have deterred individuals from reporting conflicts.

Homicide is a complex phenomenon that can be influenced by multiple factors, including income inequality, financial disputes, and mental health issues^53,54,55. Pandemic-specific factors that may have contributed to changes in homicide rates include increased gun sales, higher alcohol consumption, intimate partner violence, and child abuse⁵⁶. Additionally, disruptions in law enforcement operations and decreased community supervision may have further influenced crime trends. Factors such as unemployment and economic difficulties arising from stay-at-home mandates, combined with increased interactions among household members, may have also contributed to heightened tensions and conflicts that could lead to violence.

Conversely, the observed reduction in homicide rates can be associated with fewer gatherings in venues such as bars, nightclubs, and shopping centers, as well as locations related to drug trafficking and prostitution¹⁴. Additionally, the decreased incidence of brawls, armed assaults, and homicides may reflect diminished social interactions in urban environments⁴⁵. However, the effects of the pandemic varied significantly by region; cities with stricter restrictions exhibited lower crime rates, although these levels began to return toward pre-pandemic figures as restrictions were relaxed¹⁷.

Homicides can be classified into two categories: those arising from involvement in criminal activities, such as drug trafficking, robberies, domestic disputes, and reprisals; and those resulting from motives such as sexual assaults, kidnappings, and unclear motivations²⁹. The relatively stable homicide rates during the pandemic may indicate that many incidents occurred within household settings, which might have been less influenced by external lockdown policies. Furthermore, homicides resulting from conflicts between criminal factions or drug trafficking disagreements may be less influenced by alterations in individuals’ daily routines¹⁶.

Gender differences in homicides

A noteworthy gender disparity emerged in homicide trends during the pandemic: while male homicide rates decreased from 2017 to 2019, female homicide rates exhibited an increase from 2017 to 2020. This upward trend in female homicides in 2020 is intriguing, as it cannot be solely attributed to the pandemic. It indicates a need for further research to discern whether such increases would have occurred independently of pandemic circumstances. Overall, these findings highlight the complex interplay between the COVID-19 pandemic and homicide rates, emphasizing notable variations by gender.

Overall findings

Our findings reveal that different types of crime evolved in distinct ways throughout the pandemic, aligning with existing literature while also uncovering unique regional dynamics. This inconsistency highlights the importance of considering local contexts when assessing crime trends. The observed discrepancies underscore the intricate interplay of various factors—criminal, social, economic, health-related, and demographic—that influence crime trends and vary by region¹⁷. Furthermore, a global analysis has indicated that stricter movement restrictions during the pandemic correlated with more substantial declines in crime rates¹⁶, further illustrating the multifaceted nature of crime dynamics in crisis situations. By elucidating these nuanced differences, our research provides valuable insights into the understanding of crime dynamics during crises, specifically within the context of Kerman Province. Our work addresses a critical gap in the literature concerning the socio-economic drivers that shape these crime trends, which is essential for informing future research and policy decisions.

Ultimately, research exploring these dynamics will be critical in developing tailored responses that meet the unique needs of communities grappling with the lasting impacts of the pandemic. Such inquiries can reinforce policy recommendations aimed at mitigating crime during both emerging and enduring crises.

Recommendations for a comprehensive approach

To mitigate crime during and after crises like the COVID-19 pandemic, we propose the following multifaceted strategies:

Enhancing community policing

Strengthening community policing initiatives can build trust between law enforcement and residents, particularly in vulnerable neighborhoods. Increased police presence in these areas can foster relationships that facilitate intelligence-sharing and address the root causes of crime. Evidence from Liberia indicates that regular interactions between law enforcement and communities reduced mob violence by approximately 40%⁵⁷. Similarly, police-community partnerships in Ethiopia have enhanced public confidence and effectively addressed crime-related issues through collaborative community programs⁵⁸.

Utilizing technology: Law enforcement agencies are encouraged to adopt technological advancements to support crime prevention and response strategies. This includes employing data analytics to identify crime hotspots, establishing remote reporting systems, and utilizing video conferencing for court proceedings⁵⁹. Such technologies can enhance public safety while adhering to social distancing protocols and can also improve overall police performance through swift investigative processes. Various countries have adopted technologies such as electronic surveillance and automatic ticketing, demonstrating their effectiveness in crime control⁶⁰.

Implementing targeted interventions: Addressing crime exacerbated by pandemic conditions requires targeted interventions. Community-based violence intervention programs tailored to mitigate gun violence and violent crime through conflict mediation, mentorship, and support services have garnered positive results. Evidence from England demonstrates that specific interventions yield better outcomes than broad measures, minimizing potential collateral damage⁶¹.

Investigating root causes of crime: Investigating the socio-economic determinants of crime—such as unemployment, mental health issues, and substance abuse, along with investing in social services, job creation programs, and mental health resources, can help prevent crime in the long term. Research in the United States has indicated strong correlations between economic instability and delinquency, emphasizing the necessity for job creation programs to ease poverty and subsequently reduce crime⁶². Furthermore, addressing mental health and substance abuse treatment is vital, as youth engaged in such programs tend to exhibit lower rates of detention and criminal behavior⁶³.

Promoting international cooperation: International cooperation is essential in combating transnational organized crime during the pandemic. This can involve sharing intelligence, coordinating law enforcement initiatives, and enhancing cross-border collaboration to disrupt criminal networks. A study within the U.S.-Canada context shows the effectiveness of collaborative transnational policing practices, which serve to prevent crime in the illicit economy through informal, ad hoc negotiations⁶⁴.

Policy implications and future research

Our findings indicate varied outcomes across different contexts, primarily presenting observed trends without establishing clear causal relationships. Since correlations do not imply causation, any policy recommendations should be approached with caution. However, our research identifies several potential areas for proactive measures, including enhancing communication, implementing crisis management protocols, supporting vulnerable populations, fostering community engagement, and strengthening law enforcement outreach. These initiatives may aid in conflict resolution and enhance overall community safety. Given the complexities surrounding crime during the pandemic, there is an urgent need for robust empirical research to inform effective policy actions. Future studies should focus on establishing empirically supported causal relationships and examining the socio-economic factors driving these crime trends. Additionally, further empirical investigations are necessary to validate these findings and address ongoing issues in this evolving context.
