Unincorporated communities


Note: Unlike most Arkansas counties, Clark County only has one single township. That township encompasses the entire county.

Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States Census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Clark County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.
