A bleg: Request for Some Demographic Data

By Mike Kimel Hi. I’m looking for the US population aged 35 to 44 and 45 to 54 from 1929 to the present. I’m having a great deal of trouble extracting it from the Census. Does anyone have that data, ideally from a publicly available source? If so, please drop me a line at “mike” period “kimel” (one m only) at gmail.com Thanks.
