The United States acquired the area of Arkansas from France as part of the Louisiana Purchase in 1803. Arkansas Territory (spelled in the enabling act as Arkansaw) was organized from part of Missouri Territory on March 2, 1819, and included the greater part of Oklahoma, west to the 100th meridian. Arkansas Territory was reduced in area in 1824 and 1828 to generally assume the boundary of the present state. Arkansas was admitted to the Union on June 15, 1836, as the 25th state.
Although the territory had not yet been established, census data are available for Arkansas beginning with the 1810 census (as part of Louisiana Territory). The 1810 and 1820 populations for Arkansas reflect the 1819 boundary of the territory, which included territory now in the state of Oklahoma. The population of the entire legally established Louisiana Territory (of which the area of Arkansas was a part) in 1810 was 20,845.
Data for the legally established state of Arkansas are available beginning with the 1840 census.
