Notes:
The ethnic group “White” presumably includes Jewish (i.e. Edomitish) people so that numbers relating to the ethnic group “White” are presumably overstated.
I first compiled these numbers some time in 2021. The data in the sources above has changed since that time, however these numbers can be relied upon to provide an indicative portrayal of changes in the ethnic composition of the population of the United States of America, in terms of both absolute numbers and percentages.
