The surname Rainey is of Anglo-Saxon origin, derived from the Old English word "regn" meaning rain. It was originally a descriptive name given to someone who lived near a rainy area or whose land was prone to heavy rainfall.
One of the earliest recorded instances of the name Rainey can be found in the Domesday Book of 1086, where it appears as "Reigni" and "Reigney". This suggests that the name was well-established in parts of England by the 11th century.
During the Middle Ages, the name was commonly spelled as "Rayne", "Raynee", and "Rayney". It was particularly prevalent in the counties of Yorkshire, Lancashire, and Staffordshire, where many places bore names derived from the Old English word "regn", such as Rainhill, Rainford, and Rainow.
Noteworthy historical figures with the surname Rainey include Sir Thomas Rainey (c. 1510-1582), an English politician who served as Lord Mayor of London in 1573. Another prominent bearer of the name was Sir William Rainey (1587-1655), an English landowner and Member of Parliament for Aldborough.
In Scotland, the Rainey family can trace their roots to the 16th century, with records indicating that a John Rainey was a burgess of Aberdeen in 1568. The name was also present in Ireland, where it is believed to have been introduced by English settlers during the Plantation of Ulster in the 17th century.
One of the most famous individuals with the surname Rainey was Sir William Rainey Harper (1856-1906), an American academic and the first president of the University of Chicago. Other notable Raineys include Thomas Rainey (1843-1876), an American soldier and recipient of the Medal of Honor during the American Civil War, and Freda Rainey (1887-1963), an American archaeologist and anthropologist who conducted extensive research in Alaska.

Demographics
Among Census respondents with the surname Rainey, the largest self-reported group is White at 60.5%. The next largest groups are Black (30.8%) and Two or More Races (4.3%).
The bar chart below shows how Rainey bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Rainey surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
