Buchanan County Census Records:

Missouri did not become a state until 1821 and the geographic area where Buchanan County, Missouri is located did not become part of the state until the Platte Purchase which occurred in 1837. Census records for Buchanan County are available from 1840 to 1930. 


The area where Buchanan County is located was not part of Missouri at this time; therefore there was no census enumeration for Buchanan County recorded in 1810. At this time period, Buchanan County was part of unsettled Indian Lands. Also, all Federal census records for the other districts were lost.


This area was still not part of Missouri; therefore there was no census record in 1820 for Buchanan County. It was still part of the Indian Lands. Census records for all existing counties were lost.


This area was still not part of Missouri; therefore, no 1830 census records exist for Buchanan County. The 6 most northwest counties were part of the unorganized territories. The Platte Purchase of 1837 added this region to the state at that time and opened up the area to settlers. The census records for the counties that had been created by 1830 are available. Clay County was the western most county and ran from the Missouri River north to the Iowa border.
