Origin
The surname ISITT has its origins in England, traceable back to the 13th century. It is a locational name derived from the village of Isitt in Derbyshire. The earliest recorded spelling of the place name was "Isshete" in the Domesday Book of 1086.
ISITT is believed to have evolved from the Old English words "isic" meaning "a small stream" and "sete" meaning "a dwelling". This suggests the name originated from a settlement situated near a small stream or brook.
One of the earliest recorded bearers of the name was Roger de Isshete, mentioned in the Pipe Rolls of Derbyshire in 1273. In the 14th century, the name was found in various spellings such as Isshite, Isshed, and Isshet.
The ISITT surname is also linked to several notable historical figures. Among them was Sir John Isitt (1518-1596), a prominent landowner and Member of Parliament for Derbyshire during the reign of Queen Elizabeth I.
Another notable bearer of the name was Thomas Isitt (1645-1711), a respected clergyman who served as the Rector of St. Peter's Church in Nottingham for over 40 years.
In the 18th century, the name was associated with Benjamin Isitt (1725-1795), a successful merchant and philanthropist from Bristol, who made significant contributions to the city's development.
The ISITT surname also gained recognition in the literary world through the works of poet and writer John Isitt (1778-1857), whose poems and essays were widely published in his time.
One of the earliest recorded examples of the surname in its modern spelling appeared in the parish records of Derbyshire in the late 16th century, where a family by the name of ISITT was documented.
Demographics
Among Census respondents with the surname Isitt, the largest self-reported group is White at 88.2%. The next largest groups are Hispanic (6.3%) and Two or More Races (4.7%).
The bar chart below shows how Isitt 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 Isitt 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.
