Origin
Meaning and origin of Thropp
The surname Thropp is of English origin, emerging in the late medieval period around the 13th century. It is believed to have derived from the Old English word "throp," meaning a small village or hamlet. This suggests that the name may have initially referred to someone who lived in a small settlement or hamlet.
One of the earliest recorded instances of the name Thropp can be found in the Subsidy Rolls of Worcestershire, England, dating back to 1327. In these records, a certain John Thropp was listed as a taxpayer in the village of Droitwich.
During the 16th century, the name appears to have been concentrated primarily in the counties of Worcestershire and Gloucestershire in the West Midlands region of England. An entry in the parish records of St. Michael's Church in Gloucester from 1572 mentions the baptism of a child named Alice Thropp, daughter of Thomas and Alice Thropp.
In the 17th century, the Thropp name gained some prominence with the birth of Sir William Thropp (1609-1679), a notable English lawyer and Member of Parliament. He served as a judge during the reign of Oliver Cromwell and was later knighted by King Charles II.
The surname Thropp is also linked to several place names in England, such as Thropp Green in Herefordshire and Thropp Mill in Worcestershire. These place names likely derived from the same Old English word that gave rise to the surname.
Another notable individual with the Thropp surname was John Thropp (1718-1792), a British naval officer who served during the American Revolutionary War. He achieved the rank of Captain and was involved in several naval engagements against the French and Spanish fleets.
In the 19th century, the name Thropp is recorded in various census records and parish registers across England, particularly in the West Midlands region. One notable figure was Elizabeth Thropp (1821-1906), a renowned educator and philanthropist who founded several schools for underprivileged children in Gloucestershire.
While the surname Thropp may not be as widely known as some other English surnames, it has a long and rich history that can be traced back to the medieval period. The name's origins reflect the rural settlements and villages that dotted the English countryside, providing a glimpse into the lives of those who bore this distinctive surname.
Demographics
Ancestry and ethnicity for Thropp

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 Thropp surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
