Origin
The surname Dalrymple is of Scottish origin and dates back to the 12th century. It is derived from the lands of Dalrymple, near Ayr, in the county of Ayrshire. The name is believed to come from the Gaelic "dail" meaning "meadow" or "haugh" and the Scots word "rympill" meaning a small stream or rivulet.
The earliest recorded spelling of the name was in the year 1240, when John de Dalrymple was granted lands in the parish of Dalrymple. By the 13th century, the Dalrymples had established themselves as a prominent landowning family in Ayrshire.
The Dalrymple name appears in various historical records, including the Ragman Rolls of 1296, which list several individuals with the surname who swore fealty to King Edward I of England. In the 14th century, the Dalrymples were involved in the Wars of Scottish Independence, supporting the cause of Robert the Bruce.
One of the earliest notable members of the Dalrymple family was Sir John Dalrymple (1448-1512), who served as Lord Provost of Edinburgh and played a key role in the construction of the city's famous Royal Mile.
Another famous Dalrymple was James Dalrymple (1619-1695), who rose to become the 1st Viscount of Stair and served as Lord President of the Court of Session, Scotland's highest civil court. His son, John Dalrymple (1673-1747), was also a prominent figure, known as the 2nd Earl of Stair and serving as a distinguished military commander during the War of the Spanish Succession.
In the 18th century, Sir David Dalrymple (1726-1792) made significant contributions to Scottish history and antiquities as a lawyer, judge, and author. He was also a notable figure in the Scottish Enlightenment.
The Dalrymple surname has been associated with various place names throughout Scotland, such as Dalrymple Castle in Ayrshire and the town of Dalrymple, which was once the family's ancestral seat.
Demographics
Among Census respondents with the surname Dalrymple, the largest self-reported group is White at 87.6%. The next largest groups are Black (4.6%) and Two or More Races (3.6%).
The bar chart below shows how Dalrymple 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 Dalrymple 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 Dalrymple (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.
