What are the possible levels/options for the geography argument in tidycensus::get_acs(geography = ???)?
I've seen it work as follows:
library(tidycensus)
census_api_key("YOUR API KEY GOES HERE")
vt <- get_acs(geography = "county",
variables = "B19013_001",
state = "VT")
slc_value <- get_acs(geography = "tract",
variables = "B25077_001",
state = "UT",
county = "Salt Lake County",
geometry = TRUE)
states <- get_acs(geography = "state",
variables = "B19013_001")
Are all of the census geographic entities available? (https://www2.census.gov/geo/pdfs/reference/geodiagram.pdf)
And if so how can I specify nation or Zipcode? This code doesn't work:
nation <- get_acs(geography = "nation",
variables = "B19013_001")
