In 2019, 46.8 million people in the U.S. identified their race as Black, up from 36.2 million in 2000, or a 29% increase. This population growth is faster than that of the White population, but slower than that of the Asian or Hispanic population. Increasing shares of Black people consider themselves multiracial or Hispanic, and this is especially common among those who are members of Gen Z or younger.
I find this interesting, but not surprising. (It helps explain to me why certain folks in Georgia are fighting so hard to surpress/restrict voting):
Just over half of all Black people in the U.S. live in the South, a share that has risen some in recent decades. The growth of the Black population in the South suggests a departure from previous Black migration patterns. After the start of the Great Migration in the late 1910s, growing shares of the Black population lived in regions of the U.S. outside of the South. But after 1970, the share of this population that lived in the South started to grow, a trend that continues today.
Overall, there was a 4 percentage point increase in the share of the Black population that lives in the South between 1970 (52%) and 2019 (56%).
