The city of Bogota implemented a lockdown during the pandemic under which only men were allowed out on odd days and only women were allowed out on even days. Crime rates in Bogota increased, relative to a synthetic Bogota and relative to the pre-period, during this gender-based lockdown. Moreover, this increase is driven by more crime on men-only days and, more specifically, more robberies with male victims on men-only days. There is no evidence that higher crime rates on men-only days are offset by lower crime rates on women only days. In fact, there is evidence of some increases in crimes with female victims on women-only days. There was an increase in robberies involving female victims on women-only days during the second half of the lockdown, when some restrictions were eased and more men, and thus more potential perpetrators, were on the streets. Overall, the gender-based lockdown, if anything, increased crime.
