The surname Kemp originated in England during the medieval period, deriving from the Old English word "cempa" or "kempa," meaning a soldier, warrior, or champion. The name first emerged in areas such as Kent, Surrey, and Essex, which were strongholds of the Anglo-Saxon settlers.

The surname Kemp also has connections to place names in England, such as Kemp Town, a coastal area in Brighton, and Kempton Park in Middlesex.

Demographics
Among Census respondents with the surname Kemp, the largest self-reported group is White at 69.5%. The next largest groups are Black (21.7%) and Two or More Races (4.7%).
The bar chart below shows how Kemp 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 Kemp surname at the time of the 2020 Census, not any inherent property of the name itself.
