Data
Correcting a typo and reprojecting to UTM…
counties <- read_sf("data/DuBoisChallenge - Georgia Counties w 1870 & 1880 data.shp") |> clean_names() |> pivot_longer(starts_with("data"), names_to = "year", values_to = "pop", names_pattern = "(\\d{4})") |> mutate(pop = if_else(pop == "> 1000", "< 1000", pop)) |> st_transform("EPSG:32617")
