census.data: Census Data by year
In akeyel/wnvdata: West Nile Virus Public Data Sets

Description Usage Details Source

Census data came from US Census Bureau Population Estimation Program accessed using library(censusapi) (requires api key in .Renviron ... or maybe not if doing less than 500 calls per day) listCensusMetadata("pep/int_population", type = "variables", vintage = 2000) listCensusMetadata("pep/int_population", type = "geography", vintage = 2000) listCensusMetadata("pep/population", type = "variables", vintage = 2019) The variables do change somewhat because they change between “vintages” of the data. There might be a better way to pull that together. Each dataset only covers a decade, so to get longer periods you have to stich them together.
