To examine 10-year trends in offending by females in New South Wales (NSW) between 2014 and 2023. METHOD Data were extracted from the NSW Police Force’s Computerised Operational Policing System (COPS) for all people proceeded against by the NSW Police Force between 2014 and 2023. The number and proportion of offences committed by female and male offenders are presented. Offending trends are examined across 32 specific offence categories using the average annual percentage change in offences and the Kendall’s rank order correlation test to determine statistical significance. This analysis is conducted for the entire population of female and male offenders regardless of age, then repeated for the subset of young offenders. RESULTS Between 2014 and 2023 the number of females proceeded against by NSW police increased by 40%, compared to just 17% for males. The proportion of female offenders grew by around 15%, from 19% of all offenders in 2014 to 22% of all offenders in 2023. Female offenders were most commonly proceeded against for steal from retail store (12%), possess/use drugs (12%), domestic violence (DV) assault (11%), non-DV assault (7%) and breach bail conditions (7%). Much of the overall growth in female offending can be explained by increases in a small number of high-volume offence categories. These include: breach of Apprehended Violence Orders (12% increase in female offences from 2014 to 2023 versus a 7% increase in male offenders); breach bail conditions (12% vs. 8%); DV assault (8% vs. 2%); and non-DV assault (4% vs. 1%). The average annual number of female offenders (compared to males) also increased across several lower volume offences, although these contributed less to the growth in female offending overall. Most predominantly: sexual touching, sexual act and other sexual offences (13% vs. 2.5%); motor vehicle theft (12% vs. 9%); prohibited weapons offences (8% vs. 4%); break and enter non-dwelling (7% vs. stable); and trespass (6% vs. 3%). Trends and offending patterns were similar for young female offenders aged 10-17 years. One difference was the number of young female offenders grew by just 20% between 2014 and 2023 (compared to relatively stable trends for young male offenders). CONCLUSION While there has been a long-term increase in the number of female offenders proceeded against by the NSW Police Force, they continue to represent a small proportion of all offenders. Further analysis utilising representative surveys may provide insight int

Background: City-specific temporal analysis has been commonly used to investigate the impact of COVID-19-related behavioural regulation policies on crime. However, these previous studies fail to consider differences in the intensity of intervention among cities and the impact of these behavioural regulation policies on crime trends nationwide. This study performs panel data analyses to examine how the declaration of a state of emergency (SoE) affected ambient population and crime in Japan, taking advantage of the fact that the SoE was implemented at different times in different prefectures. Methods: The current study uses two sets of panel data of 47 prefectures for 22 weeks from February to July 2020: (1) the data on ambient population in five types of locations provided by the Google Mobility Reports, and (2) official crime data of six types of crime: residential burglary, commercial burglary, theft of/from vehicle, bicycle theft, sexual assault, and violence and injury. Firstly, an ordinary least squares regression analysis was performed to examine the impact of the SoE on the ambient population. Then a negative binomial model with fixed effects was adopted to examine the effect of the ambient population on the crime trends. Findings: The SoE declaration was found to increase the ambient population in 'residential', and decrease that in other settings including 'workplaces', 'transit stations', and 'retail and recreation' in targeted prefectures. Spill-over effects of the SoE were observed on the ambient population of non-SoE prefectures. The ambient population have impacted five out of the six types of crime examined, except for sexual assault. After controlling for the ambient population, we observed an increase in commercial burglary and theft of/from the vehicle in all prefectures during the SoE weeks, compared to the weeks when the SoE was not declared. Conclusions: The declaration of the SoE during the COVID-19 pandemic changed the ambient population in the SoE-prefectures, resulting the changes in crime levels as well. In addition, the implementation of the SoE in specific prefectures was found to have a contextual impact on national-level crime trends. Furthermore, the implementation of the SoE caused changes in some crime types that could not be explained by the changes in the ambient population, suggesting that the implementation of the SoE affected offenders' decision-making. It is also worth noting that the changes in ambient population and crime trends during the pandemic were observed in Japan where the behavioural regulation policy without law enforcement was introduced.
