 ## Data
 
 What exactly is returned when calling `getIds` is dependent on the source data used. The default data in `/data/` is generated from [this file in the JOSM project](https://josm.openstreetmap.de/export/HEAD/josm/trunk/resources/data/boundaries.osm). It...

The data set currently includes all subdivisions only for the 🇺🇸 United States, 🇨🇦 Canada, 🇦🇺 Australia, 🇨🇳 China, 🇮🇳 India, 🇫🇲 Micronesia and 🇧🇪 Belgium plus a few subdivisions for other countries.
