\description{
The 50 states and District of Columbia — all naming and coding
systems used to refer to each state. The backing data for \code{\link[=state_convert]{state_convert()}}.
}
\details{
Naming convention: underscore objects (\code{state_ids}, \code{state_facts},
\code{state_geo}) are modern purpose-built tibbles. Convenience vectors
(\code{state_abbs}, \code{state_names}, etc.) mirror the base R
\verb{datasets::state.*} vectors but cover all 51 rows (50 states + DC).
