Subset of Ludwig-Miller data. Counties with missing poverty rate, of with
both outcomes missing (
mortality) were removed. In the
original dataset, Yellowstone County, MT (oldcode=27056) was entered twice,
here the duplicate is removed. Yellowstone National Park, MT (oldcode=27057)
is also removed due to it being an outlier for both outcomes. Counties with
oldcode equal to (3014, 32032, 47010, 47040, 47074, 47074, 47078, 47079,
47096) matched more than one FIPS entry, so the county labels may not be
correct. Mortality data is missing for Alaska.
