The Eleventh United States Census was taken June 2, 1890. The data was tabulated by machine for the first time. The data reported that the distribution of the population had resulted in the disappearance of the American frontier. Most of the 1890 census materials were destroyed in a 1921 fire.
The 1890 census announced that the frontier region of the United States no longer existed, and that the Census Bureau would no longer track the westward migration of the U.S. population. Up to and including the 1880 census, the country had a frontier of settlement. By 1890, isolated bodies of settlement had broken into the unsettled area to the extent that there was hardly a frontier line. This prompted Frederick Jackson Turner to develop his Frontier Thesis.
The original data for the 1890 Census is no longer available. Almost all the population schedules were damaged in a fire in the basement of the Commerce Building in Washington, D.C. in 1921. Some 25% of the materials were presumed destroyed and another 50% damaged by smoke and water (although the actual damage may have been closer to 15–25%). The damage to the records led to an outcry for a permanent National Archives. In December 1932, following standard Federal record-keeping procedures, the Chief Clerk of the Bureau of the Census sent the Librarian of Congress a list of papers to be destroyed, including the original 1890 census schedules. The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, but the Librarian did not accept the census records. Congress authorized destruction of that list of records on February 21, 1933, and the surviving original 1890 census records were destroyed by government order by 1934 or 1935. The other censuses for which some information has been lost are the 1800 and 1810 enumerations.

The data yielded by this census provided strong evidence that the United States' policies towards Native Americans had had a significant impact on the enumeration of the census in the second half of the 19th century. US domestic policy combined with wars, genocide, famine, disease, a declining birthrate, and exogamy (with the children of biracial families declaring themselves to be white rather than Indian) accounted for the decrease in the enumeration of the census.
