Eleven Southern states are home to more than 500 groups that promote hate speech, according to a detailed breakdown by the Southern Poverty Law Center. But it’s California that is home to the largest number of organizations that preach hate, the center found.

The SPLC tracks 939 active groups that promote racial, ethnic or religious segregation or hate. The eight types of hate groups the center has identified include white nationalists, black separatists, neo-confederates, Christian identity, skinheads, Ku Klux Klans and neo-Nazis, along with a handful of miscellaneous groups.

California has 77 such groups, while Florida and Texas are home to 58 and 57 hate groups, respectively. Here’s the SPLC’s map of where hate groups live:
