Data precision
There is no generally valid designation for the next administrative level of countries. "Nager.Date" supports the initial subdivision of a country, but we will not support a detailed level because the effort required is too high.
To keep it generally valid, we will treat this subdivision as SubdivisionCodes, this will replace the current designation Counties.
