Demographics

Crime

Gang violence and poverty is elevated in Trappes. There are also Islamists among its Muslim population, with 70 locals suspected of having left to Iraq and Syria to fight for the Islamic State in the 2010s.

In July 2013, mob attacked the local police station following the arrest of a man who had assaulted a police officer during an identity check on his wife (the burqa is illegal in France). In August 2018, a man on the terror watchlist killed his mother and sister before being shot dead by police. While the Islamic State claimed responsibility, French interior minister Gérard Collomb described the man as “unstable,” rather than likely to follow the terror group’s instructions.

In October 2026, a man killed a person and wounded five others in a spree shooting targeting three neighborhoods, which President Macron described as a racist terror attack. The antiterrorism prosecutor opened an investigation into the suspects racist or islamophobic motives.

Education
