County Demographics 1969-2023 (Cleaned and Reshaped CDC SEER County Population Data)

A nice clean panel of basic demographic information for every US county from 1969 to 2023. Variables include total population, percent white, percent black, percent male, percent children (age 0-17), and percent seniors (age 65+).

This is a cleaned and reshaped version of the CDC SEER data available here: https://seer.cancer.gov/popdata/download.html

I also include a panel of county-level data from the Area Health Resources File, which has economic variables like household income, poverty rate, and unemployment rate. But AHRF only goes back to 1975 and has a lot more missing variables, so use the SEER files unless you really need the economic variables.
