#' Centers of population of US states according to the 2000 census
#'
#' A data set of the latitude and longitude coordinates of the centers of
#' population (centroids) of the US states plus the District of Columbia.
#' Populations according to the 2000 decennial census are also included.
#'
#' Note that this dataset does not contain Puerto Rico data, unlike
#' \code{\link{state2010}} and \code{\link{state2020}}.
#'
#' Furthermore, unlike \code{\link{county2000}}, \code{state2000} does not
#' contain data from Puerto Rico, American Samoa, Guam, the Northern Mariana
#' Islands, or the US Virgin Islands.
#'
#' The
#' \href{https://www2.census.gov/geo/docs/reference/cenpop2000/statecenters.txt}{source
#' data file} on the US census website has different column names than what its
#' \href{https://www.census.gov/geographies/reference-files/time-series/geo/centers-population.2000.html}{data
#' dictionary} reports. The data dictionary's version of the column names were
#' used, since they are consistent with the majority of the other data files and
#' data dictionaries on the census website.
