Countries' fourth-level administrative divisions.

Please note: This category's subcategories contain articles on each subdivision of the country while each directly included article considers the subdivisions structure of the country.

Further note: This category's subcategories are indexed according to country, but its directly included articles are not: they are indexed by type of subdivision (provinces, counties, etc). Articles with non-English subdivision terms in their titles either have their redirects indexed instead, or are indexed by the common English translation for said subdivision. This facilitates comparisons between similarly named subdivisions.
