The Ku Klux Klan still “poses a threat to society,” though it is relatively unstable and unorganized, according to the Anti-Defamation League.

The findings of an ADL report released this week found that 42 KKK groups are active in 33 states, with an estimate of some 3,000 members. More than half the groups were either formed or restarted in the past three years.

Most of the groups are concentrated in the South and the East, with a slight increase since early 2016.
