Census data (census.gov) says about 0-14 is 25% of the black population, 15-24 is 15%, 25-44 is 30%, 45-64 is 20%, and 65+ is 10%. Rough numbers, but close enough. For black males, that’s 21.5 million total. Toss out the under-13s (since 13-50 is our range) and the over-50s, call it 25% under 13 (5.4 million) and 30% over 50 (6.5 million).
