1890年美国人口普查(英語:1890 United States Census)以1890年6月2日为普查日,它确定美国常住人口为62,979,766人,比1880年人口普查时统计的50,189,209人增加了25.5%。这些数据是第一次用机器制表。数据表明,人口的分布导致了美国边境的消失。大多数的1890年人口普查资料在1921年的一场大火中被摧毁了,只有阿拉巴马州、佐治亚州、伊利诺伊州、明尼苏达州、新泽西州、纽约州、北卡罗来纳州、俄亥俄州、南达科他州、得克萨斯州和哥伦比亚特区部分数据幸免于难。

The data yielded by this census provided strong evidence that the United States' policies towardsNative 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, andexogamy (with the children of biracial families declaring themselves to be white rather than Indian) accounted for the decrease in the enumeration of the census.Chalk, Frank; Jonassohn, Kurt.The History and Sociology of Genocide: Analyses and Case Studies.
