Daylight Savings Causes Crime Spike

While many Americans gripe about losing sleep when clocks “spring forward,” the extra hour of darkness after clocks “fall back” can lead to increased crime rates, according to recent research.

Crime Rates After Daylight Saving Time Ends

A new study by Vivint, a smart home company, reveals a significant rise in crime across the United States following the end of daylight saving time (DST). The study, based on FBI data from 2017 to 2021, shows that both the percentage and total number of crimes increased after the clocks were turned back. Notably, robberies and vehicle thefts saw the highest spikes, with robberies becoming 64.4% more likely and vehicle thefts increasing by 61%. The raw number of robberies surged by 81%. Additionally, break-ins rose by 16%, though homes with security systems experienced fewer incidents.

The Role of Darkness in Crime

Research indicates that maintaining daylight saving time year-round could reduce crime rates, particularly robberies. A 2015 study by the Brookings Institution suggested that eliminating the “fall back” could reduce robberies by 27%, directly due to the additional daylight in the evenings. Similarly, a 2012 study by Jennifer Doleac and Nicholas Sanders found that crimes such as robberies, murders, and rapes decreased after the “spring forward” shift. Conversely, a 2017 study published in the Journal of Experimental Criminology noted a rise in assaults in major U.S. cities immediately after DST ended.

“Most crimes happen under the cover of darkness,” said Joseph Giacalone, a retired NYPD sergeant and professor at John Jay College of Criminal Justice. “Most burglaries occur when people leave home for work or school, and the extended darkness in the morning after setting the clocks back might be a contributing factor.” To mitigate the risks associated with increased darkness, it is recommended you follow several safety measures, including installing home security systems, exterior lighting, and ensuring doors and windows are locked. Closing curtains and blinds at night can also enhance security.

Legislative Efforts

The biannual clock changes have also faced criticism in the U.S. Senate. With a majority of Americans opposed to turning back the clocks every fall, lawmakers introduced the Sunshine Protection Act to eliminate the need for this change. Senators who sponsored the bill argue that year-round DST would not only reduce crime but also decrease car accidents, boost the economy, reduce the risk of seasonal depression, and benefit farmers.

The impact of daylight saving time on crime rates underscores the complex relationship between time changes and public safety. As the debate over clock changes continues, the importance of community awareness and preventative measures remains clear.
