Baby Name Popularity Calculator

Baby name popularity trend analysis uses Social Security Administration (SSA) birth name data to calculate a name’s rank, frequency, and trajectory over time. Understanding popularity trends helps parents choose names that are well-known without being overused, or find names rising in popularity before they peak.

Name frequency formula: Name Frequency (%) = (Babies Given This Name in Year ÷ Total Babies Born that Year) × 100

Rank change formula: Rank Change = Previous Year Rank − Current Year Rank (Positive number = rising in popularity; negative = falling)

Popularity trajectory: Trend = Average Rank Change over Last 5 Years

Where:

• SSA Rank: names are ranked 1 (most popular) through 1,000+ each year, separately for boys and girls
• Frequency: the percentage of babies given a name. A #1 name today takes only about 1% of babies of that sex. In the 1940s and 1950s the leader took three or four times that.
• Vintage Score: a name’s approximate peak decade (helps assess whether it’s classic, retro-trending, or dated)

Name diversity context: The US has become significantly more diverse in name choices over decades:

• 1950: Top 10 names accounted for ~25% of all babies
• 1980: Top 10 names: ~15% of all babies
• 2000: Top 10 names: ~8% of all babies
• 2022: Top 10 names: ~5% of all babies

This means a name ranked #50 today is effectively more common than a name ranked #20 in 1970.

Peak popularity indicator: A name is likely near its peak if:

• Rank improved by 50+ positions in the last 3 years AND
• Celebrities have recently given the name to their children AND
• The name is in the Top 20 for its gender

Worked example: Name: “Olivia” (girls’ list).

• 2018: rank #2, behind Emma
• 2019: rank #1
• 2023: rank #1

Rank change from one year to the next: none. Trend: stable at the top. Olivia has led the girls’ list every year since 2019.

Implication for parents: this is the part people get wrong. Being the single most popular name in the country sounds crowded, but it still means only about one girl in a hundred. In a typical class of 24 there are perhaps a dozen girls, so a second Olivia in the same room is the exception rather than the rule. What you will notice is one or two more in the same school year.

The drop below #1 is steeper than most people expect. The top ten together take about 5% of babies of each sex, but they are not 0.5% apiece: the leader takes roughly twice what #10 does. That is why the calculator gives an individual share for a top-ten name and a band average for everything below it, where the differences between neighbouring ranks stop mattering. All of these figures are approximate and move a little every year.

A name in the 50 to 150 range gives distinctiveness while staying recognizable, and that is where most parents who research this end up.
