Yes I believe it.
Many immigrants and hispanics have came here. The population increases and the percentages change b/c of it, but the number of black people stays the same.
Ex. There are 25/100 blue balls in a bag. That means 25% of the balls in the bag are blue. More balls were added, none of them were blue. There are still 25 blue balls in the bag, but since more balls were added there are 25/200 blue balls in the bag. That changes the percentage of blue balls in the bag to 12.5% even though the same number of blue balls are still inside of the bag.
You get it now?
The number of blackpeople is the same, it's just that the number of other races in the U.S have increased dramatically, especially hispanic/latino.
Why are our numbers still the same? Abortions, people not wanting to have kids or start families, deaths, murders, gang violence.
I'm not sure if Africans who came from Africa (like those whose ancestors weren't US slaves, just to be clear) are included with the percentage of black people/African americans. It can be confusing, that's why some people think we should have a different name that African American.
All except Northern Africans are counted as black
