What Is a Name Popularity Calculator — How Popular Is Your Name??

See how popular any first name is in the US by decade. Rankings from SSA data (1900–2020s). Find peak popularity, current rank, and trend direction. This calculator runs entirely in your browser — your data stays private, and no account is required.

How Name Popularity Is Measured

The Social Security Administration (SSA) tracks every name given to babies born in the United States and has published this data since 1900. Rankings are based on the total number of babies given a particular name in each decade. A rank of #1 means that name was the single most popular name for that decade. The SSA excludes names with fewer than 5 occurrences in a given year for privacy reasons, so very rare names won't appear in the rankings.

Trends in American Names

American naming patterns have shifted dramatically over the decades. In the early 1900s, a handful of names dominated — John, James, Mary, and Helen accounted for a huge share of all babies. By the 2000s, naming had diversified enormously, and even the #1 name represents a much smaller percentage of total births. Traditional names like Henry, Evelyn, and Theodore have staged comebacks after decades of obscurity. To find what day of the week you were born, try the Day of the Week Calculator.

Using This for Baby Names

If you're choosing a baby name, this tool helps you understand whether a name is trending up (becoming more common) or fading (becoming more unique). Some parents prefer classic names that have held steady for decades. Others want something that was once popular but is now rare — giving their child a familiar-sounding name that won't have three classmates with the same one. Check the trend indicator to see which direction a name is heading. For more birthday facts, try the Date Pattern Calculator.

Pop Culture Effects

Names are heavily influenced by celebrities, movies, TV shows, and current events. Jennifer was barely ranked before 1960 but became #1 in the 1970s, widely attributed to the 1970 film Love Story. Madison appeared after the 1984 movie Splash. Arya and Khaleesi surged during Game of Thrones. The On This Day in History tool can show you what was happening culturally in the decade your name peaked.

Most Popular Baby Names in the U.S. (2025)

How Baby Name Popularity Is Measured

In the United States, baby name popularity data comes from the Social Security Administration (SSA), which has published annual baby name frequency data since 1880. The SSA tracks every name given to five or more babies of the same sex in a given year, covering approximately 98% of all births. Popularity is expressed as a rank (the most common name is rank 1) and as a frequency (the number of babies given that name per million births). These two metrics can diverge: a name might maintain the same rank while its frequency drops if all popular names are becoming less common — which is exactly what has been happening since the mid-20th century as naming culture has diversified.

In the 1950s, the top 10 boy names accounted for approximately 30% of all male births. By 2024, the top 10 account for less than 8%. This dramatic shift reflects a cultural movement toward individuality in naming — parents increasingly choose distinctive names rather than defaulting to traditional popular options. The practical consequence is that a name ranked 50th today is proportionally rarer than a name ranked 50th in 1960. A boy named James in 1955 shared his name with about 4.5% of all boys born that year. A boy named the 50th-most-popular name today shares it with approximately 0.2% of boys — over twenty times rarer in proportional terms despite holding the same rank position.

Naming Trends and Patterns

Name popularity follows identifiable patterns that sociologists and linguists have studied extensively. The "100-year rule" observes that names popular a century ago often experience revivals — names like Eleanor, Henry, Violet, and Theodore that peaked around 1910-1920 have surged back into the top 50 over the past decade. This cycle occurs because grandparents' names sound dated, great-grandparents' names sound old-fashioned, but great-great-grandparents' names sound vintage and fresh. Meanwhile, parents' generation names (Jennifer, Jason, Jessica, Brandon) feel too recent and common to seem distinctive.

Cultural influences create rapid spikes in name popularity. The name Arya was rarely used before the television series Game of Thrones premiered in 2011 — by 2019 it ranked among the top 100 girls' names. Khaleesi, another character name from the same series, entered the top 1000 despite being a fictional title in a constructed language. Similarly, the name Madison barely appeared in SSA data before the 1984 film Splash used it as a joke (the mermaid character names herself after Madison Avenue), after which it climbed to the second most popular girls' name by 2001. These pop-culture driven spikes typically last 10-15 years before declining, leaving a generational fingerprint — much like how Shirley, Scarlett, and Rhett trace back to Gone with the Wind (1939).

Geographic and Demographic Variation

Name popularity varies significantly by region, ethnicity, religion, and socioeconomic status. Names popular in the American South (such as Waylon, Colton, and Paisley) differ from those popular in the Northeast (such as Theodore, Charlotte, and Sebastian). Hispanic naming traditions favor Juan, Mateo, Sofia, and Valentina — names that have risen in overall US popularity as the Hispanic population has grown. Religious naming traditions produce geographic clusters: Hebrew names like Moshe and Rivka are concentrated in areas with large Orthodox Jewish communities, while Arabic names like Muhammad (which has been the most popular name for baby boys in England and Wales in several recent years) reflect both immigration patterns and religious practice.

Spelling variations create tracking challenges. Is Kaitlyn the same name as Caitlin, Katelyn, Katelynn, and Caitlyn? Phonetically yes, but the SSA counts each spelling separately. When spellings are combined, many names rank significantly higher than any individual spelling suggests. The name Aiden/Aidan/Ayden/Aden collectively would rank among the top 5 boys' names in several recent years, but split across four or more spellings, no single variant cracks the top 10. This fragmentation makes it appear that naming culture is more diverse than it actually is — the sounds parents choose are more concentrated than the spellings suggest.

Using Name Data for Research and Genealogy

Historical name frequency data is a powerful tool for genealogical research, helping narrow search windows when census or vital records are incomplete. A person named Brittany is almost certainly born between 1985 and 2000 (the name was virtually nonexistent before 1980 and has declined sharply since). A woman named Ethel was very likely born between 1890 and 1930. These temporal signatures can confirm or challenge family stories about birth years and help distinguish between multiple individuals with common surnames. Name popularity data also reveals immigration patterns — spikes in names like Giuseppe, Giovanni, and Maria correspond to periods of Italian immigration, while increases in Wei, Mei, and Jian reflect Chinese immigration waves.
