The United States acquired most of the area of North Dakota from France in 1803 as part of the Louisiana Purchase. It obtained the area in the north and northeast part of the present-day state by a convention, signed with Great Britain in 1818 that extended the northern boundary along the 49th parallel. Dakota Territory was organized on March 2, 1861, from unorganized area formerly within Minnesota Territory and part of Nebraska Territory. Dakota Territory included all of the present-day states of North Dakota and South Dakota, most of Montana, the northern half of Wyoming, and a small part of Nebraska. The territory was reduced in 1863 with the organization of Idaho Territory, enlarged in 1864 with the addition of most of the remainder of present-day Wyoming, and again reduced with the organization of Wyoming Territory in 1868. In 1882, the state of Nebraska acquired an area north of the Keya Paha River and Niobrara River. North Dakota was admitted to the Union simultaneously with South Dakota on November 2, 1889, as the 39th and 40th states, with generally the same boundaries as the present states.
Census data for the combined area in present-day North Dakota and South Dakota are available in the 1860 census (and listed in national tables with South Dakota). The 1860 census population is for territory reported as "unorganized Dakota" and includes population in areas now in Montana. The 1860 population excludes some population enumerated in Nebraska Territory. Although the state had not yet been legally established, the 1870 and 1880 populations generally are for the area of the present state. The population of Dakota Territory as legally established was 135,177 in 1880 and 14,181 in 1870.
Data for the legally established state of North Dakota are available beginning with the 1890 census.
