Origin
Meaning and origin of Decarteret
The surname DECARTERET is of French origin, derived from the Norman French phrase "de Carteret" meaning "of Carteret." This name is believed to have originated in the Channel Islands during the 11th or 12th century.
The Carteret family was a prominent Norman family who held lands and titles in the Channel Islands, particularly on the island of Jersey. The name likely referred to their estate or landholdings in the village of Carteret on Jersey.
One of the earliest recorded instances of the name appears in the 1165 Assize Roll of Jersey, which mentions a "Rainaldus de Carteret." In the 13th century, the Carteret family was granted the title of Seigneur de Carteret, a feudal lordship over the parish of St. Ouen on Jersey.
Sir Renaud de Carteret (c. 1235-1298) was a notable member of the family who served as a knight and fought in the Seventh Crusade. He was granted additional lands in Jersey for his service.
The name DECARTERET was later adopted by branches of the family who settled in other parts of France, as well as in England and the British colonies. Variations of the spelling included Carteret, Cartrett, and Carterett.
In the 17th century, Sir George Carteret (1610-1680) was a prominent figure in the English court and served as a Royalist during the English Civil War. He later became one of the proprietors of the Province of New Jersey in America, which was named in his honor.
Another notable bearer of the name was John Carteret, 2nd Earl Granville (1690-1763), a British statesman and diplomat who served as Secretary of State and Lord President of the Council.
Philip Carteret (1639-1693) was a British naval officer and the first governor of New Jersey, appointed by the proprietors in 1665. He established the first capital of the colony at Elizabethtown.
These are just a few examples of the historical figures who bore the surname DECARTERET, which has a rich legacy tracing back to its Norman roots in the Channel Islands.

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 Decarteret 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.
