Census
Trevor in the 2020 Census
The 2020 Census recorded 145,682 people with the first name Trevor, which placed it at #384 in the published first-name tables. This is a snapshot of people who already had the name at the time of the Census.
The SSA sections elsewhere on this page answer a different question: how often parents gave the name to babies over time. The "people living today" figure on this page is different again: it is a current estimate built from SSA birth records and age-based survival rates, so the two numbers are not expected to match exactly.

Demographics
Ancestry and ethnicity for Trevor
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Trevor is White at 81.8%. The next largest groups are Black (7.1%) and Two or More Races (4.7%). These figures describe the people who had the name in 2020, not any inherent property of the name itself.
The bar chart below shows how people with the first name Trevor 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 name, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown so the breakdown is easy to read across every published category. Because the 2020 Census first-name file also includes raw headcounts for each group, Name Census can show those alongside the percentages in the legend and hover tooltip.
Keep in mind that these are self-reported numbers. A first name does not determine a person's race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the name Trevor at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Trevor
The name Trevor is of Welsh origin, deriving from the word "tref" meaning "town" or "settlement." It is believed to have emerged during the Middle Ages, around the 12th or 13th century, when Welsh names were becoming more prevalent.
One of the earliest recorded instances of the name Trevor can be found in the Domesday Book, a comprehensive survey of England and Wales commissioned by William the Conqueror in 1086. Here, the name appears as a place name, suggesting it may have initially been used as a surname before transitioning into a given name.
The first known historical figure to bear the name Trevor was Trevor the Monk, a Welsh clergyman and historian who lived in the late 12th century. He is best known for his work "Brut y Tywysogion" (Chronicle of the Princes), a valuable record of Welsh history and events from 682 to 1196.
In the 14th century, Sir Trevor de Blaney, a prominent Welsh landowner and military commander, played a significant role in the Wars of Scottish Independence, fighting alongside Edward I against the Scots.
During the English Renaissance period, Trevor Vaughan (1544-1604) was a renowned Welsh poet and scholar, known for his poetic works in both Welsh and English.
In the 17th century, Trevor Hill (1616-1653) was an English Puritan minister and author who played a prominent role in the English Civil War, supporting the Parliamentarian cause.
Another notable figure was Trevor Barlow (1676-1737), an English clergyman and author who served as the Bishop of Lincoln from 1723 until his death.
Throughout history, the name Trevor has been borne by various individuals from different walks of life, including writers, artists, politicians, and military leaders. Its rich Welsh heritage and historical significance have contributed to its enduring popularity over the centuries.

FAQ
Trevor: questions and answers
How many people in the U.S. are named Trevor?
Name Census puts the figure at roughly 156,205 living Americans. We arrive at this by taking every SSA birth registration for Trevor going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 2,194 US residents.
Is Trevor a common name?
We classify Trevor as "Common". It ranks above 99.7% of all first names in the SSA dataset by living bearers. Across the full history of the data, 161,369 babies have been registered with this name.
When was Trevor most popular?
The single biggest year for Trevor was 1998, when 6,616 babies received the name. The fact that the average living Trevor is about 31 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Trevor in the 2020 Census?
The published 2020 Census first-name tables recorded 145,682 people with the name Trevor, or 48.23 per 100,000 residents. That placed it at #384 in the national Census ranking for first names.
Why is the Census count different from the living estimate?
Because they measure different things. The Census figure is a count of people who had the name Trevor in 2020. The living estimate aims to answer a current question instead: how many people with the name are alive today, based on SSA birth records and age-based survival rates. Since one number is a 2020 snapshot and the other is a present-day estimate, they are not expected to be identical.
What does the Census say about the gender split for Trevor?
In the 2020 Census sex table, Trevor appears almost entirely male. Of the 145,694 people counted with this name, 99.8% were male and only a very small share were female. The Census view is a snapshot of people living with the name in 2020, while the SSA section above tracks births across time.
What does the Census say about the background of people named Trevor?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Trevor is White at 81.8%. The next largest groups are Black (7.1%) and Two or More Races (4.7%). These figures describe the people who had the name in 2020, not any inherent property of the name itself. The percentages in the chart above come from self-reported race and Hispanic-origin responses in the 2020 Census.
Which group reports the name Trevor most often in the Census?
White is the largest reported group for people named Trevor in the 2020 Census, accounting for 81.8% (119,162 people in the published table).
Why can the Census sex total and race total differ slightly?
The Census Bureau published separate 2020 tables for sex and for race/Hispanic origin, and the released figures can differ slightly because of privacy protection in the public files. That is why this page treats the gender section and the race/origin section as two related snapshots instead of forcing them into one identical total.
Does every first name have Census demographic data?
No. The public Census first-name release only includes names that met the Bureau's publication rules, so many rarer names in the SSA files have no Census demographic snapshot. When that happens, the SSA trend, gender history, and state sections still appear, but the 2020 Census demographic sections are omitted.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Trevor in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Trevor a male name?
Yes, 99.6% of people registered as Trevor in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Trevor still being used today?
Yes. The SSA still recorded Trevor in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Trevor can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate.
