Oklahoma Boundary, Census, and Statehood History
Oklahoma was acquired by the Louisiana Purchase of 1803. It soon became an area of settlement for various Indian tribes displaced from States farther east, and was known as the Indian Territory although it had various tribal governments rather than a central administration. Many non-Indians also settled in the area. Oklahoma Territory was established from a part of the Indian Territory in 1890 and expanded in 1893; the tribal jurisdictions continued in the remainder. On November 16, 1907 the two parts were admitted as the State of Oklahoma, with substantially the current boundaries. A dispute about the western boundary was settled in Texas' favor by the U.S. Supreme Court in 1930.
Census coverage did not systematically include any of present-day Oklahoma until 1890; some Indian areas were first enumerated in 1900. In 1860 non-Indians were enumerated but not included in official population totals; non-Indians in the area in 1870 and 1880 were not enumerated. The 1890 total is for Oklahoma Territory (78,475) and Indian Territory (180,182); and the 1900 total is for Oklahoma Territory (398,331) and Indian Territory (392,060). Just prior to statehood, the U.S. Census Bureau took a special census on July 1, 1907, showing a total population of 1,414,177 (Oklahoma Territory, 733,062; Indian Territory, 681,115); results of this special census are included in the Oklahoma table.
