Origin
The surname MacDonald has its origins in Scotland, where it first appeared in the 13th century. The name is derived from the Gaelic "Mac Dhòmhnaill," meaning "son of Donald." This suggests that the earliest bearers of the name were descendants of a man named Donald.
One of the earliest recorded instances of the name can be found in the Exchequer Rolls of Scotland, which mention a "Donald MacDonald" in 1292. The name was also present in other medieval Scottish records, such as the Ragman Rolls of 1296, which lists several individuals with the surname MacDonald who swore fealty to King Edward I of England.
The MacDonalds were a powerful clan in the Western Isles of Scotland, and their history is closely intertwined with the region's turbulent past. In the 14th century, the clan was led by John MacDonald, who was granted the title of Lord of the Isles by King Robert II. This marked the beginning of the MacDonalds' prominence as a dominant force in the region.
Notable historical figures bearing the MacDonald surname include:
1. Somerled MacDonald (c. 1100-1164), a Norse-Gaelic military leader and progenitor of the Clan Donald.
2. John MacDonald, Lord of the Isles (c. 1337-1386), a powerful Scottish nobleman and chief of the Clan Donald.
3. Flora MacDonald (1722-1790), a Scottish heroine who famously aided Bonnie Prince Charlie's escape after the Battle of Culloden in 1746.
4. Ramsay MacDonald (1866-1937), a British politician who served as Prime Minister of the United Kingdom on two occasions.
5. John A. MacDonald (1815-1891), a Canadian statesman and the first Prime Minister of Canada.
The name MacDonald has also been associated with various place names, particularly in Scotland, such as Islay, where the Clan Donald had a strong presence. Over time, the spelling of the name has evolved, with variations like McDonald, MacDonell, and McDonnell emerging in different regions.
Demographics
Among Census respondents with the surname Macdonald, the largest self-reported group is White at 90.5%. The next largest groups are Hispanic (3.6%) and Two or More Races (3.2%).
The bar chart below shows how Macdonald 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 Macdonald surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Macdonald (2000, 2010, 2020).
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.
