#' @title US City, state, and ZIP
#' @description This tibble is the third version of a popular zipcodes database.
#'   The original CivicSpace US ZIP Code Database was created by Schuyler Erle
#'   using ZIP code gazetteers from the US Census Bureau from 1999 and 2000,
#'   augmented with additional ZIP code information from the Census Bureau’s
#'   TIGER/Line 2003 data set. The second version was published as the
#'   `zipcode::zipcode` dataframe object. This version has dropped the latitude
#'   and longitude, reorganized columns, and normalize the city values with
#'   [normal_city()].
#' @format A tibble with 44,336 rows of 3 variables:
#' \describe{
#'   \item{city}{Normalized city name.}
#'   \item{state}{Two letter state abbreviation.}
#'   \item{zip}{Five-digit ZIP Code.}
