Origin
The surname Laidlaw originated in the Borders region of Scotland. It is a locational name, derived from the lands of Laidlaw near Jedburgh in Roxburghshire. The name is thought to come from the Old English words "lad" meaning a path and "hlaw" meaning a hill, thus describing a path over a hill.
The earliest recorded spelling of the name is believed to be William de Laidlau, which appears in the Ragman Rolls of 1296. These were the rolls of homage to Edward I of England, and included many Scottish names. This suggests the Laidlaw family held lands in this area as far back as the late 13th century.
In 1535, a John Laidlaw is mentioned in the records of the Burgh Court of Jedburgh. He is recorded as being a burgess, or freeman, of the town. This indicates the family had achieved a level of status and prominence by this time.
William Laidlaw (1780-1845) was a renowned Scottish author and scholar. He worked as an amanuensis for Sir Walter Scott and assisted him with several of his works, including Ivanhoe and The Heart of Midlothian. Laidlaw is also known for his own poetry and writings on Scottish culture and history.
Another famous bearer of the name was Thomas Laidlaw (1829-1904), a Scottish-born civil engineer. He emigrated to Australia in the mid-19th century and oversaw the construction of several major railway lines, including the Victorian Railways system.
In the United States, James Laidlaw (1795-1859) was an early settler in Illinois. He emigrated from Scotland in the 1830s and founded the town of Laidlaw, which was later renamed Kankakee. His descendants became prominent landowners and businessmen in the region.
The Laidlaw name can also be found in other parts of the world where Scottish emigrants settled, such as Canada, New Zealand, and South Africa. Notable bearers include Sir Patrick Laidlaw (1831-1916), a Scottish-born businessman and politician who served as Mayor of Cape Town.
Demographics
Among Census respondents with the surname Laidlaw, the largest self-reported group is White at 83.2%. The next largest groups are Black (8.0%) and Two or More Races (4.1%).
The bar chart below shows how Laidlaw 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 Laidlaw 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 Laidlaw (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.
