The Surname Johnson on Both Sides of the Atlantic
Johnson is far more dominant as a surname in the United States than in the United Kingdom, even though the name originated in England.
In the US, the latest Census Bureau surname analysis places Johnson second, behind only Smith. Roughly 1.93 million Americans carry it. That works out to about 580 Johnsons per 100,000 people, making the surname one of the most common identifiers in the country. The high US ranking comes partly from English colonial settlement, partly from formerly enslaved Black Americans adopting the surname after emancipation, and partly from Scandinavian immigrants who simplified Johansson, Johansen, or Johannessen on arrival at Ellis Island.
In the UK, Johnson ranks much lower. The Office for National Statistics analysis of surname frequency places Johnson around 25th to 30th in England and Wales, behind Smith, Jones, Williams, Brown, Taylor, Davies, and others. The total UK count of Johnsons is in the low hundreds of thousands rather than the millions. Most British Johnsons live in northern England, particularly Yorkshire and Lancashire, with a secondary cluster in central Scotland.
The reason for the gap traces back to immigration history. The US accumulated Johnsons from multiple sources, while the UK only ever had the native English-Scottish supply. There were never any Scandinavian Johanssons becoming British Johnsons in large numbers, because the simplification of Scandinavian surnames happened almost entirely on arrival in America.
Thomas as a First Name: UK Leads
The trend reverses sharply when we look at first names.
In the United States, Thomas currently ranks around 50th to 60th for boys born today, according to SSA data. It peaked early in the 20th century, sat in the top 10 from the 1900s through the 1940s, and has been gently declining ever since. About 7,000 American boys were named Thomas in the most recent year of published data.
In the United Kingdom, Thomas remains a top 15 boys' name. ONS data shows roughly 3,500 boys named Thomas born in England and Wales annually, with similar proportional usage in Scotland and Northern Ireland. Per capita, that means a UK newborn boy is roughly twice as likely to be named Thomas as an American newborn boy.
Several factors contribute. British naming traditions skew somewhat more classical and biblical than American trends, where invented or modernized spellings have gained ground. Thomas also has strong associations in British royal and historical contexts (Thomas Becket, Thomas More, Thomas Hardy) that keep the name culturally current in a way the US never quite matched.
Side-by-Side Statistical Comparison
Here is a snapshot comparison of how the name Thomas Johnson registers in each country.
| Metric | United States | United Kingdom |
|---|---|---|
| Surname Johnson rank | 2nd | 25th to 30th |
| Total Johnsons | about 1.93 million | about 280,000 to 330,000 |
| First name Thomas rank | 50th to 60th | Top 15 |
| Annual Thomas births | about 7,000 | about 3,500 (England and Wales) |
| Estimated Thomas Johnsons | 11,000 to 14,000 | fewer than 2,500 |
| Highest regional concentration | Mid-Atlantic, Midwest | Yorkshire, Lancashire, central Scotland |
| Peak usage decade | 1900s to 1920s | 1880s to 1910s |
The estimated total of full-name Thomas Johnsons in each country is calculated by multiplying the first-name frequency by the surname frequency and adjusting for known correlations. The result is approximate but defensible. There are roughly five to six times as many Thomas Johnsons walking around the United States as the United Kingdom, even though the UK actually produces new Thomas babies at a higher per-capita rate.
Regional Patterns Within Each Country
Both countries show clear geographic clustering for the surname Johnson, and the patterns differ in instructive ways.
In the United States, Johnson density is highest in a band stretching from the Mid-Atlantic states (Maryland, Virginia, Pennsylvania) through the Midwest (Ohio, Illinois, Wisconsin, Minnesota). The Maryland cluster reflects early colonial settlement, including the family that produced Thomas Johnson, the state's first governor and a contemporary of George Washington. The Minnesota and Wisconsin clusters reflect later Scandinavian immigration. Southern states have substantial Johnson populations as well, particularly among Black Americans whose families adopted the surname in the 19th century.
In the United Kingdom, the Johnson clusters trace a different history. Yorkshire and Lancashire in northern England have the highest concentrations, reflecting the surname's origins in medieval England. A secondary cluster appears in central Scotland, particularly around Glasgow and Edinburgh, where Lowland Scottish naming customs absorbed English patronymic patterns earlier than Highland regions did.
Within each country, a person named Thomas Johnson is more likely than average to come from these specific regions. Outside those regions, the combination remains possible but proportionally less common.
Historical Trajectory: When the Name Peaked
The combined name Thomas Johnson followed parallel arcs in both countries, with the UK slightly ahead.
British usage of the combined name peaked between the 1880s and 1910s, when both Thomas and Johnson were near their highest combined frequencies. The early 20th century saw a gradual decline as Thomas became somewhat less fashionable and Johnson's relative position among UK surnames slowly drifted downward.
American usage peaked slightly later, with the strongest combined frequencies appearing between 1900 and the 1920s. Census data from this era shows Thomas Johnson appearing repeatedly in industrial cities (Pittsburgh, Detroit, Chicago) where both Anglo-American families and Scandinavian immigrants congregated. Postwar usage declined gradually rather than sharply, and the name has stabilized in recent decades rather than continuing to fall.
Both countries show one common pattern: the combined name is now more often inherited (encountered in middle-aged and older populations) than chosen anew. New parents naming a child Thomas in the UK might pair it with a different surname, and new American Johnsons might choose first names that feel fresher to contemporary ears. The name Thomas Johnson, in short, is doing what most established names do over generations: aging gracefully rather than dying out, but not being newly chosen at the rate it once was.
