Origin
Meaning and origin of Lapworth
The surname LAPWORTH is of English origin and dates back to the medieval period. It is a locational surname, derived from the place name Lapworth, a village in Warwickshire, England. The name is thought to be derived from the Old English words "laeppe" meaning "a loop or bend" and "worth" meaning "an enclosure or homestead," suggesting it referred to a homestead near a bend in a river or road.
The earliest recorded instance of the surname LAPWORTH appears in the Domesday Book of 1086, where it is spelled "Lapeworde." This suggests the name was already well-established by the time of the Norman Conquest in 1066. Other early spellings include "Lapeworth," "Lappeworth," and "Lapeworthe."
In the 13th century, records show a Roger de Lapworth who was a landowner in Warwickshire. In the 14th century, a John Lapworth is mentioned in the Court Rolls of the Manor of Wakefield in Yorkshire, indicating the name had spread beyond its place of origin.
One notable bearer of the LAPWORTH name was Samuel Lapworth (1647-1707), an English clergyman and chaplain to King William III. Another was Charles Lapworth (1842-1920), a pioneering British geologist who made significant contributions to the study of graptolites and the stratigraphy of the Ordovician and Silurian periods.
Other historical figures with the surname LAPWORTH include Edward Lapworth (1819-1880), a British architect responsible for designing several churches and public buildings in Warwickshire, and Ralph Lapworth (1873-1943), a British chemist who made important discoveries in stereochemistry.
The LAPWORTH name has also been associated with several place names in England, such as Lapworth Street in Warwickshire and Lapworth Green in Staffordshire, further reinforcing its locational origins.

The bar chart below shows how Lapworth 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 Lapworth surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
