I am shocked that I cannot put my finger on this information and I must resort to asking here. I am looking for U.S. population estimates from 1790-present. Preferably there is an estimate for each year, but I am ok with just the census values every 10 years. I have tried navigating the U.S. Census Bureau's website for at least an hour with unsatisfactory results.
I have also found this website, but I am looking for something which looks more citable.
