Well, that was fun while it lasted.
In the most recent data from the Census Bureau the white population of the US dropped, in numerical terms. It did not merely drop as a percentage of the overall population. (Though it did that too, rather dramatically.)
The actual number of white people fell.
By 8.6% since 2010.
The New York Times: “Meanwhile, the white population, in absolute numbers, declined for the first time in the history of the country.”
It also dropped as a percentage of the population, from 63.7 percent in the 2010 census to 57.8 in the 2020 census, the lowest percent on record.
