Origin
The surname CODER is of English origin, arising in the late 16th century. It is an occupational name derived from the Middle English word "codder", which referred to a person who made or sold cod, a type of fish. The name likely emerged in coastal regions where fishing was a major industry.
In its earliest recorded appearances, the name was often spelled as "Codder". For instance, a John Codder was listed in parish records from Whitby, Yorkshire in 1592. Over time, the spelling evolved to its modern form, CODER, reflecting changes in pronunciation.
While not a particularly common surname, CODER can be found in historical documents from various parts of England. One notable early bearer of the name was William CODER (c.1620-1689), a merchant and shipowner from Bristol who played a role in the city's maritime trade.
Another individual of note was Thomas CODER (1701-1778), a farmer and landowner from Lincolnshire. Records indicate he owned substantial estates in the village of Tattershall.
During the 17th and 18th centuries, some bearers of the CODER surname migrated to the American colonies. One of the earliest recorded instances was that of John CODER, who arrived in Virginia from London in 1635.
As the name spread across England and later to other parts of the English-speaking world, it occasionally took on variant spellings. For example, the birth of a Samuel COADER was recorded in Devon in 1712.
Other notable historical figures with the CODER surname include:
- James CODER (1775-1849), a British naval officer who served during the Napoleonic Wars.
- Henry CODER (1829-1905), an English architect who designed several churches and public buildings in London.
- Elizabeth CODER (1860-1942), an American educator and advocate for women's rights, born in Ohio.
- Charles CODER (1887-1961), a Canadian politician who served as a member of the House of Commons.
While not among the most prevalent surnames, CODER has a long and interesting history, reflecting its origins in the coastal fishing communities of medieval England.
Demographics
Among Census respondents with the surname Coder, the largest self-reported group is White at 89.2%. The next largest groups are Two or More Races (3.9%) and Hispanic (3.8%).
The bar chart below shows how Coder 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 Coder 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.
