On OpenStreetMap, the United States Virgin Islands is split into two districts, the Saint Thomas-Saint John District and the Saint Croix District, when in actuality it should be divided into three districts.
Also the short names of all the county equivalents of the United States, according to the state censuses, are as follows. Note: UM stands for United States Minor Outlying Islands.
The 1966 Reapportionment Act merged the St. Thomas and St. John Districts into a single St. Thomas–St. John District. This is an electoral district, which would be tagged boundary=political. The U.S. community has long shied away from mapping any legislative districts on the mainland because they tend to shift without any trace on the ground. Meanwhile, the Census Bureau continues to recognize separate St. Thomas Island and St. John Island “counties” and their subdistricts.
Currently, we have a single boundary=administrativeadmin_level=6 relation for St. Thomas–St. John District. We also have a pair of distinct boundary=censusborder_type=district relations for St. Thomas and St. John, which correspond to what the Census Bureau considers county-equivalents. Does the USVI government officially align its administrative subdivisions to the legislative districts, the census geographies, or something else? All I can tell from their website is that they only maintain two offices, one on St. Thomas and the other on St. Croix. Do you have something we can cite as the districts that date back to the 1990s?
