library("fs")
dir_create("data")

dir_target <- path("data", "download")
dir_create(dir_target)
download.file(

  path(dir_target, "us-counties.csv")
)
download.file(

# we don't need to download this *every* time
file_excel <- path(dir_target, "iowa_counties_population.xls")

if (!file_exists(file_excel)) {
  download.file(
    "https://www.icip.iastate.edu/sites/default/files/uploads/tables/population/popest-annual.xls",
    file_excel
