In 1681, a James Deuchar was recorded as a Covenanter, a Protestant group that opposed the religious policies of the Scottish monarchy.
In the 18th and 19th centuries, the Deuchar family continued to be prominent in the Scottish Borders region. William Deuchar (1730-1804), a minister and writer, was born in Melrose and is known for his works on Scottish history and literature.

Demographics
Among Census respondents with the surname Deuchar, the largest self-reported group is White at 88.7%. The next largest groups are American Indian/Alaska Native (5.7%) and Hispanic (4.7%).
The bar chart below shows how Deuchar bearers described their own race and ethnicity on the 2010 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 Deuchar surname at the time of the 2010 Census, not any inherent property of the name itself.

Not necessarily. Deuchar appears here with 2010 Census data, while the latest surname file loaded on Name Census is 2020. When a surname drops below the Census publication threshold, older rows can still be kept for historical reference even if the name no longer appears in the newest file.
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.
