Census
Thommy in the 2020 Census
The 2020 Census recorded 148 people with the first name Thommy, which placed it at #45,698 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 Thommy
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thommy is White at 30.4%. The next largest groups are Asian/Pacific Islander (23.6%) and Hispanic (23.0%). 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 Thommy 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 Thommy at the time of the 2020 Census, not any inherent property of the name itself.

Origin
Meaning and history of Thommy
The name Thommy has its origins in the Hebrew name Thomas, which is derived from the Aramaic word "te'oma" meaning "twin." It is believed to have been introduced to Europe through early Christian traditions and the New Testament.
As Christianity spread, the name Thomas became popular throughout the Mediterranean region and Western Europe. In Greek, it was rendered as "Θωμάς" (Thōmas), and in Latin, it became "Thomas."
One of the earliest recorded uses of the name Thomas can be found in the Bible, referring to the apostle Thomas, also known as "Doubting Thomas." This biblical figure played a significant role in the spread of Christianity and the acceptance of the name.
Throughout history, the name Thomas has been borne by numerous notable individuals. One of the most famous was St. Thomas Aquinas (1225-1274), an Italian Dominican friar, philosopher, and theologian whose works had a profound impact on Western thought.
Another important figure was Thomas More (1478-1535), an English lawyer, scholar, and statesman who served as Lord Chancellor under King Henry VIII. He was canonized as a Catholic saint in 1935 for his refusal to accept the king's claim to be the supreme head of the Church of England.
Thomas Edison (1847-1931), the American inventor and businessman, is perhaps one of the most well-known bearers of the name. He is credited with developing many devices that greatly influenced modern life, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb.
In the literary world, Thomas Hardy (1840-1928) was an English novelist and poet who is best known for his novels "Far from the Madding Crowd," "Tess of the d'Urbervilles," and "Jude the Obscure."
The name Thommy is a variant spelling of Thomas, likely originating as a diminutive or nickname form. While not as common as the traditional spelling, it has been used throughout history, particularly in certain regions or cultures.

FAQ
Thommy: questions and answers
How many people in the U.S. are named Thommy?
Name Census puts the figure at roughly 15 living Americans. We arrive at this by taking every SSA birth registration for Thommy 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 22,850,289 US residents.
Is Thommy a common name?
We classify Thommy as "Very Rare". It ranks above 35.3% of all first names in the SSA dataset by living bearers. Across the full history of the data, 17 babies have been registered with this name.
When was Thommy most popular?
The single biggest year for Thommy was 1960, when 6 babies received the name. The fact that the average living Thommy is about 51 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
How common was Thommy in the 2020 Census?
The published 2020 Census first-name tables recorded 148 people with the name Thommy, or 0.05 per 100,000 residents. That placed it at #45,698 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 Thommy 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 Thommy?
In the 2020 Census sex table, Thommy leans strongly male. 150 people counted with this name were male (97.4%), compared with 4 female bearers (2.6%). 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 Thommy?
In the 2020 Census race and Hispanic-origin table, the largest reported group for people named Thommy is White at 30.4%. The next largest groups are Asian/Pacific Islander (23.6%) and Hispanic (23.0%). 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 Thommy most often in the Census?
White is the largest reported group for people named Thommy in the 2020 Census, accounting for 30.4% (45 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 Thommy in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Thommy a male name?
Yes, 100.0% of people registered as Thommy 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 Thommy still being used today?
Yes. The SSA still recorded Thommy 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 Thommy 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.
