One in Three American Boys Got a Name Ending in N. That Just Peaked.
The share of American boys given a name ending in the letter N rose from 13% in the 1940s to 35% in the 2010s. In the 2020s it fell for the first time in eighty years.
Naming trends are normally discussed as individual names rising and falling. Underneath that there is a slower layer that almost nobody tracks: the shape of names. Aggregate every birth by the last letter of the name and a pattern appears that no single name would reveal.
One letter, eight decades

The boys’ line is one of the largest structural shifts in the whole dataset, and it is entirely invisible if you look at individual names: no single N-ending name is responsible for it. It is the cumulative effect of a very large number of separate choices that happened to share a sound — and, on the evidence of the most recent decade, it has now turned over.
The girls’ line is the more surprising half. Roughly two girls in five have been given an A-ending name in every decade on record, through enormous turnover in which names those were. The individual names churn completely; the sound does not. That combination — near-total instability in names, near-total stability in their shape — is the single strongest argument that naming fashion operates on sound rather than on names.

Names also got longer, then started shrinking
Weighted by births, the average American boy’s name has moved from 5.57 letters in the 1880s to 5.69 in the 2020s, peaking in between rather than climbing steadily. The full series is in the table above. It is a small range in absolute terms, but it moves with the same timing as the N curve, which suggests both are reflections of one underlying fashion cycle rather than two independent ones.
Method, and what this cannot tell you
- What is computed. Every recorded birth is grouped by decade, sex and the final character of the name, and reported as a share of all recorded births for that decade and sex. Figures are birth-weighted, not name-weighted: a name given to 30,000 babies counts 30,000 times, which is the only way to describe what children were actually called.
- Letters, not sounds. This measures orthography. The final letter is a decent proxy for the final sound in English but not a reliable one, and this study makes no phonetic claim. We deliberately do not report syllable counts here: the syllable figures elsewhere on this site are produced by an algorithm rather than by phonetic transcription, and they are not solid enough to carry a finding.
- Length is exact. Mean length is a straightforward character count of the recorded spelling, birth-weighted.
- The most recent decade is incomplete. The final decade in the table covers only the years so far, so it is a smaller sample than the others and could still move.
- US records before about 1937 are not a birth register. The Social Security Administration’s name data comes from card applications, so the early years count only people who later applied for a card — which understates births and skews toward people who lived long enough to need one. Figures before 1937 should be read as indicative of relative popularity, not as complete counts.
- This study reports timing only. We make no claim about what caused any movement in the data: attributing a naming shift to a film, a public figure or an event is an interpretation, not a measurement, and this page does not make one.

Other studies in this series
- The end of the shared nameIn 1880 the ten most popular boys’ names covered 44% of all American newborn boys. Today they cover 8%. The same collapse appears in every country whose birth register is deep enough to measure it.
- How fast names travelOn a fixed panel of nine national registers with an equal observation window, the median time for a name to spread from its first country to its fourth fell from 113 years to 7.
- Names that changed genderTwenty-eight American names crossed decisively from boys to girls over 146 years of birth records. Under the same test, none crossed the other way.
- When a spelling overtook its rivalSteven passed Stephen in 1949 and never gave it back. US birth records let us date the exact year one spelling of a name overtook another — something a single name page structurally cannot show.
- The biggest one-year jumpsSome names do not climb. They detonate. These are the largest single-year multiplications in 146 years of US birth records — reported without any claim about what caused them.
- Names that came back after a centuryThe folk claim is that a name needs roughly a century out of fashion before it can return. It can be tested: a set of names were common before 1930, effectively disappeared for forty years, and are common again now.
- How long number one lastsIn 146 years of US birth records there have been only 24 runs at number one. The runs are getting shorter, for the same reason behind almost every other finding in this series.
All of these draw on the same normalised registry described on the research index, and the underlying figures are queryable through the free Baby Name API.
