A global analysis of the impact of COVID-19 stay-at-home restrictions on crime

Abstract

The stay-at-home restrictions to control the spread of COVID-19 led to unparalleled sudden change in daily life, but it is unclear how they affected urban crime globally. We collected data on daily counts of crime in 27 cities across 23 countries in the Americas, Europe, the Middle East and Asia. We conducted interrupted time series analyses to assess the impact of stay-at-home restrictions on different types of crime in each city. Our findings show that the stay-at-home policies were associated with a considerable drop in urban crime, but with substantial variation across cities and types of crime. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime.

Figures

Fig. 1. Seven-day moving average time series plots of daily numbers of crimes.
a, Assault (n = 23). b, Burglary (n = 20). c, Robbery (n = 24). d, Theft (n = 16). e, Vehicle theft (n = 20). f, Homicide (n = 25). Each time series is indexed to equal 100 on the day the first stay-at-home restrictions were implemented. The blue line indicates the average trend across all cities with available data. Zero time is the date on which stay-at-home restrictions were implemented.

a, Assault (n = 23). b, Robbery (n = 24). c, Homicide (n = 21). Overall summary effects estimated using random-effects meta-analytic techniques. ES, effect size. SaH (days), number of days under stay-at-home restrictions from the beginning of 2020 until the end of the respective time series from May to September 2020. Full results by city and crime can be found in Supplementary Table 17.

a, Burglary (n = 20). b, Theft (n = 16). c, Vehicle theft (n = 20). Overall summary effects estimated using random-effects meta-analytic techniques. ES, effect size. SaH (days), number of days under stay-at-home restrictions from the beginning of 2020 until the end of the respective time series from May to September 2020. Full results by city and crime can be found in Supplementary Table 17.
Fig. 4
Fig. 4. Scatterplot depicting bivariate correlation between overall average decline in crime by city and stringency of stay-at-home restrictions (n = 27).
The overall average decline was computed using the summary effect sizes for each city reported in Supplementary Table 17, with predicted linear relationship between average decline and stay-at-home stringency index (dotted line and shaded area) and 95% confidence intervals (shaded area).
