From the Guide to 2010 State and Local Census Geography – Louisiana – History:
The United States acquired the area of Louisiana from France in 1803 as part of the Louisiana Purchase, although the area east of the Mississippi River and north of Lake Pontchartrain and the southwestern boundary were disputed with Spain until 1812. Orleans Territory, which included the greater part of Louisiana, was organized on March 26, 1804. (The Louisiana Territory, organized on March 3, 1805, did not include any of the present-day state of Louisiana; the Louisiana Territory was the portion of the Louisiana Purchase that was north of the 33rd parallel, which is the current northern boundary of the state of Louisiana.) Louisiana was admitted to the Union on April 30, 1812, as the 18th state, with generally the same boundary as the present state.
Census data for Louisiana are available beginning with the 1810 census. The 1810 population is for Orleans Territory, which conformed to the present-day state boundary.
Data for the legally established state of Louisiana are available beginning with the 1820 census.
