Origin
The surname Chadwick originates from the Old English language and can be traced back to the regions of Lancashire and Yorkshire in England during the late 11th century. It is derived from two words, "ceade" meaning "valley" and "wic" meaning "dwelling" or "village". The earliest recorded spelling of the name was "Cadewic" in the Domesday Book of 1086, referring to a place name in the region.
Chadwick is primarily a locational surname, indicating that the original bearers of the name hailed from a settlement or village situated in a valley. The name evolved over time, with variations such as Chadwyck, Chadwicke, and Chadwyk appearing in historical records.
One of the earliest documented references to the name is found in the Pipe Rolls of Lancashire from 1176, where a Robert de Chadewic is mentioned. In the 13th century, a William de Chadwyk appears in the Assize Court Rolls of Yorkshire in 1285.
During the Middle Ages, the Chadwick family established themselves as prominent landowners and gentry in Lancashire and Yorkshire. Notable individuals from this period include Sir Andrew Chadwick (c. 1390-1460), a prominent knight who fought in the Wars of the Roses, and Thomas Chadwick (c. 1510-1580), a wealthy merchant and landowner in Lancashire.
In the 16th and 17th centuries, the name continued to be well-represented in the region, with several Chadwicks serving as local officials and members of the gentry class. One notable figure was John Chadwick (1572-1648), a successful lawyer and Member of Parliament for Lancashire during the reign of King Charles I.
As the British Empire expanded, the Chadwick name spread to other parts of the world, including North America and Australia. Sir Edwin Chadwick (1800-1890), a renowned social reformer and pioneer of public health, was an influential figure in Victorian England and played a significant role in improving sanitation and living conditions for the working class.
Other notable individuals with the surname Chadwick include James Chadwick (1891-1974), a Nobel Prize-winning physicist who discovered the neutron, and Lynn Chadwick (1914-2003), a renowned British sculptor known for his abstract metal sculptures.
Demographics
Among Census respondents with the surname Chadwick, the largest self-reported group is White at 86.0%. The next largest groups are Black (5.1%) and Two or More Races (3.9%).
The bar chart below shows how Chadwick 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 Chadwick 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.
