Origin
The surname LAY originates from the Old English word "læc" meaning "meadow". It is an ancient Anglo-Saxon name that first appeared in England during the medieval period. The earliest recorded instances of the name date back to the 12th century in the counties of Somerset, Gloucestershire, and Wiltshire in the southwest of England.
LAY is believed to have derived from a topographic name for someone who lived near a meadow or open field. It may also be an occupational surname for someone who worked as a shepherd or farmer on such lands. The name is closely related to the place name "Ley" or "Lea", which refers to a meadow or clearing in a forest.
One of the earliest recorded bearers of the name is Robert de la Leye, who is mentioned in the Pipe Rolls of Gloucestershire in 1195. Another early reference is found in the Curia Regis Rolls of Wiltshire from 1208, where a William de la Leye is listed.
In the Hundredorum Rolls of 1273, which were records of landowners in England, there are several entries for individuals with the surname LAY or variations such as Leye, Laye, and Ley. These include Walter de la Leye in Oxfordshire, Richard de la Leye in Berkshire, and John de la Leye in Cambridgeshire.
The LAY surname continued to be prominent in the southwest of England throughout the medieval and early modern periods. Notable individuals with this surname include:
1. William Ley (c. 1497-1568), an English judge and Member of Parliament during the reign of Queen Elizabeth I.
2. James Ley (c. 1552-1629), an English clergyman who served as the Bishop of Bath and Wells.
3. Sir James Ley (1598-1662), an English judge and politician who served as Lord Chief Justice of the King's Bench.
4. John Lay (1583-1645), an English clergyman and religious writer who published several books on theology.
5. Benjamin Lay (1677-1759), a Quaker philanthropist and abolitionist from England who became a prominent voice against slavery in the American colonies.
The LAY surname has also been found in various place names throughout England, such as Layfield in Wiltshire, Laycock in Shropshire, and Layham in Suffolk. These places likely took their names from individuals with the surname who were early settlers or landowners in those areas.
Demographics
Among Census respondents with the surname Lay, the largest self-reported group is White at 64.3%. The next largest groups are Asian/Pacific Islander (19.0%) and Black (7.8%).
The bar chart below shows how Lay 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 Lay 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 Lay (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.
