There were 1,007 active hate groups in the United States in 2012, according to the Southern Poverty Law Center, which keeps track of such groups.

This 1,007 number includes all groups that have “beliefs or practices that attack or malign an entire class of people, typically for their immutable characteristics,” according to the SPLC.

However, websites or “groups” that appeared to consist of only a single individual were not included in this round up.

Home to 82 hate groups, including chapters of the black separatist Nation of Islam and the New Black Panther Party, neo-Nazi groups like the National Socialist Freedom Movement, and Holocaust denial groups like Inconvenient History, California had the highest number of such groups among all states.
