NYC robberies peak after school

NYC robberies peak after school

In New York City, the number of robberies spikes when kids get out of school.

Digging into the city’s open data, Ben Wellington, who writes the I Quant NY blog, wanted to find the times of day when most felonies took place. When he noticed a spike at 3 p.m., he wondered if it was related to the end of the school day.

To figure that out, Wellington first looked at crime statistics during the school year only, which showed 8 a.m. and 3 p.m. spikes in robberies on school days that don’t appear on weekends or vacation days.

Then he looked at the robberies during the months of February and April, two months that both have week-long vacations to remove any seasonal issues related to the fact that vacations are more frequent towards the end of the school year.

During those months, the number of robberies between 3 p.m. and 4 p.m. on school days  is double the number that occur on non-school weekdays, Wellington found. In all, robberies occurred 15 percent more on school days than vacation weekdays, and burglaries, felony assaults and grand larcenies occurred 8 percent more often.

Despite the rise in crime before and after school in New York, robberies have dropped 29 percent in total from 2006, and 32 percent on school days, Wellington found. Robberies committed between 3 p.m. and 4 p.m. on school days have dropped 44 percent since 2006.
