Is New York City and Chicago doing the right thing for a recount population?

Me I feel like Black and White population is being undercounted population, I think they overcounted the hispanic and asian population cause in Chicago and New York where the Puerto RIcan population had been declining fast.Black in New York and Chicago are hard to count I think they should recounted so we can get a accurate count on these ethnic population in Chicago and New York I think Oakland should do the same.
