Using local administrative data from 1826 to 1936, we document the evolution of crime ratesin 19th century France and we estimate the impact of a negative income shock on crime. Ouridentification strategy exploits the phylloxera crisis. Between 1863 and 1890, phylloxeradestroyed about 40% of French vineyards. We use the geographical variation in the timing ofthis shock to identify its impact on property and violent crime rates, as well as minor offences.Our estimates suggest that the phylloxera crisis caused a substantial increase in propertycrime rates and a significant decrease in violent crimes.
