U.S County Life Tables R Binaries 1982-2019

Zip archive of files (one per state and sex) of county-level life tables from 1928-2019 by 5yr age group in R-binary (.rds) format.

We group low-population counties and geographically coterminous neighbors (1084 total) together into county-groups (401 total) with historically consistent boundaries that exceed a minimum population threshold of 10,000 at any time point in our series. County groupings never cross state borders. 2071 counties are left ungrouped. A comma-separated variable lookup table linking the 1084 individual counties (by FIPS code) to the 401 groups are available in the USMDBcountyGroupings.csv. The individual counties in the life table files are identified by their FIPS code.
