cbcp_df: Cross-border county pairs.
In davidsovich/usgeogr: An R package for U.S. geographic data.

Description Usage Format Source

A dataset containing all of the unique cross-border county pairs in the continental United States. The dataset is constructed using the methods in in Dube, Lester, and Reich (RESTAT, 2010). Specifically, only border counties are included in the dataset, and if a county is adjacent to p > 1 counties along a border, then the county will have p > 1 replicates in the dataset. Cross-border county pairs are uniquely identified by cbcp_id. Additional metadata: (1) Number of unique border counties = 1,184 (2) Number of unique cross-border county pairs = 1,308 (3) Distribution of number of pairs for counties: 1 (256), 2 (586), 3 (239), 4 (63), 5+ (40)

cbcp_df

A data frame with 2,616 rows and 15 variables:

fips_code: County FIPS code for first county, in original string format. Each FIPS code may have greater than one replicate in the data.
county_state: State postal code corresponding to FIPS code.
neighbor_fips_code: County FIPS code for paired county, in original string format.
county_state: State postal code corresponding to neighbor FIPS code.
cbcp_id: Cross-border county pair identifier for the county and its pair. A single FIPS code may have multiple entires corresponding to each of its bordering counties and their cross-border county pair identifier. Each cross-border county pair identifier has two entries in the dataset.
state_border_id: Border identifier for county and its neighbor.
dist_bt_centers: Distance (in miles) between paired county population centers.
