Smart dumb nikka lol.....You should take time out and understand the Demographic Transition Model
Yes it does matter. Birth rate and death rate are important because, birth rate replenishes the dying population. For example, White people are dying faster than they can reproduce children
White Deaths Exceed Births in a Majority of U.S. States to replenish the dying population, that is why is it forcasted that they will be a minority soon, because they can not reproduce children to compete with the other demographics.
It's the same as for Black people, if Black people had a high death to birth ratio, as compared to the White population, our so called 12% population would not have stayed the same in 20 years.
It's not basic logic, it's scientific. What where talking about it formulation percentages, genetics, statistics, biology and ecology.
Also the Black population is always undercounted:
2020 census undercount of Blacks could be three times rate in 2010
