Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas and some may have incorporated towns or cities within part of their space. Townships have limited purposes in modern times. However, the US Census does list Arkansas population based on townships (often referred to as "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. Pulaski County only has two townships, as of 2010. They are listed below.
