Decade snapshots, explained

The name generator has an era dropdown with 8 entries: the 2025 data and 7 decade eras. A decade era is not a decade of data. It is one SSA year file — 1955, 1965, 1975, 1985, 1995, 2005, and 2015 — cut to the top 200 names per sex. Every figure below is computed at build time from the committed files, so it cannot disagree with the tables the generator reads.

Why each decade is one year

The site's rank convention, set out on the methodology page, is that a rank is a name's position within one sex for one year, ordered by descending count — the SSA's own ordering, with count ties broken alphabetically. A decade era keeps that convention only if it is drawn from one year, so the committed pipeline selects one SSA year file per decade and attaches the SSA's ranks unchanged. The result is 7 snapshot years: 1955, 1965, 1975, 1985, 1995, 2005, and 2015. Each snapshot year ends in 5. The snapshots are spaced 10 years apart, and the newest, 2015, sits 10 years before the 2025 data.

A single year is not an average, a sum, or a count of "the decade's most common names" across ten years. The committed files hold no other year between 1955 and 2025, so the site makes no statement about those years at all. The label "2010s (2015 snapshot)" is read literally: it means the top 200 names registered in 2015.

The 7 snapshots at a glance

The table lists each snapshot's #1 boy and girl name with its birth count, and the name at rank #200, the floor of the committed data for that year.

Decade snapshots: #1 and rank-200 names with counts
Era label Year #1 boy #1 girl #200 boy #200 girl
Classic 1950s (1955 snapshot) 1955 Michael (88,355) Mary (63,174) Harvey (1,289) Lydia (1,585)
Classic 1960s (1965 snapshot) 1965 Michael (80,992) Lisa (60,271) Alex (1,246) Audrey (1,660)
Classic 1970s (1975 snapshot) 1975 Michael (68,418) Jennifer (58,190) Javier (1,110) Tracie (1,225)
1980s (1985 snapshot) 1985 Michael (64,934) Jessica (48,345) Jerome (1,211) Latasha (1,323)
1990s (1995 snapshot) 1995 Michael (41,409) Jessica (27,941) Jerry (1,516) Yesenia (1,495)
2000s (2005 snapshot) 2005 Jacob (25,851) Emily (23,952) Damien (1,939) Chelsea (1,734)
2010s (2015 snapshot) 2015 Noah (19,680) Emma (20,487) Paul (2,032) Arya (1,645)

Summed, the 1955 boys' top 200 holds 1,800,948 births and the girls' 1,547,892; in 2015 the same depth sums to 1,121,667 boys and 828,605 girls. The largest #1 count in any snapshot is Michael's 88,355 boys in 1955; the smallest boys' #1 count is Noah's 19,680 in 2015. For girls the #1 count runs from Mary's 63,174 in 1955 down to Emma's 20,487 in 2015. For comparison, the 2025 #1 names are Liam (20,818 boys, #1 in no snapshot year) and Olivia (13,544 girls, #1 in no snapshot year), from a list that goes 1,000 deep.

How deep a snapshot goes

Each snapshot carries exactly 200 names per sex, and the 2025 list carries 1,000. The floor is a real name with a real count — the table above shows it for every year — and across all 7 snapshots no name inside the committed depth was registered fewer than 1,110 times in its year. Below rank #200 the committed data stops. A name absent from a snapshot's list is not necessarily absent from that year's SSA file — it may sit below the floor, which the committed files do not cover, or below the SSA's fewer-than-5 threshold — so the site describes such a name as outside the committed depth rather than as unused.

The era labels in the generator

The dropdown lists the eras newest first; every decade label names its snapshot year:

  • 2025 — latest data — top 1,000
  • 2010s (2015 snapshot) — 2015, top 200
  • 2000s (2005 snapshot) — 2005, top 200
  • 1990s (1995 snapshot) — 1995, top 200
  • 1980s (1985 snapshot) — 1985, top 200
  • Classic 1970s (1975 snapshot) — 1975, top 200
  • Classic 1960s (1965 snapshot) — 1965, top 200
  • Classic 1950s (1955 snapshot) — 1955, top 200

3 of the labels begin with the word "Classic" (1950s, 1960s, and 1970s). It is a dropdown label for the oldest snapshots and carries no claim about the names inside those lists.

Names in every snapshot's top 200

Comparing the 7 lists name by name, 43 boy names and 19 girl names sit inside the top 200 for their sex in every snapshot from 1955 to 2015. The tables give each name's best rank (the smallest rank number it reached) and lowest rank, each with its snapshot year; names are ordered by their 2025 rank.

All 43 ever-present boy names chart in the 2025 top 1,000, and 21 of them sit inside the 2025 top 100. The best-placed in 2025 is Henry at #5 (12,020 births); the lowest-placed that still charts is Bradley at #403 (794). All 19 ever-present girl names chart in the 2025 top 1,000, and 4 of them sit inside the 2025 top 100. The best-placed in 2025 is Elizabeth at #17 (6,760 births); the lowest-placed that still charts is Michelle at #465 (661).

Measured end to end rather than snapshot by snapshot, 47 of the 1955 boys' top 200 names also appear in the 2015 top 200, and 115 of them appear somewhere in the 2025 top 1,000; for girls the figures are 32 and 83.

Tiers that a snapshot cannot fill

The generator's popularity tiers are rank ranges inside the selected era's own list. Because a snapshot stops at rank 200, any tier that begins below that rank is structurally empty for every decade era, and the generator says so instead of refilling the draw from outside the filter. The counts below come from the 1955 snapshot and the 2025 list with no letter or length filter; they are identical for boys and girls, which share one depth.

Popularity tiers against the snapshot depth and the 2025 list
Tier Rank range Names in a 1955 list Names in the 2025 list Status in a decade era
Top 10 #1–#10 10 10 fully covered
Top 100 #1–#100 100 100 fully covered
Less common #101–#500 100 400 partial — reaches rank #200 only
Uncommon #501–#1,000 0 500 structurally empty

"Uncommon" (ranks 501–1,000) is empty for every decade era, by construction. "Less common" (ranks 101–500) is cut off at the snapshot floor, so in 1955 it yields 100 names per sex rather than the 400 the 2025 list provides. An empty or short result from a decade era is a statement about the committed depth, not a generator fault.

First letters, snapshot by snapshot

The same 7 lists support a per-initial reading. In 1955, the initial carrying the largest share of top-200 boy births was J at 16.2%, and for girls D at 13.8%; in the 2015 snapshot the leading initials were J (17.0%) for boys and A (20.2%) for girls. The first-letter guide tabulates all 26 initials for every snapshot and both sexes.

What a snapshot cannot tell you

  • Nothing between the years. The committed files contain the 7 snapshot years and 2025; the site does not estimate, interpolate, or describe any other year.
  • Nothing below rank #200. The ranks the 2025 list reaches past that point (down to #1,000) have no counterpart in any decade era.
  • Exact spellings only. The SSA ranks every spelling separately and strips hyphens and spaces before counting, so snapshots compare spellings, not merged variants.
  • U.S. births, card applications, per-sex ranks. The 50-states-and-D.C. scope, the fewer-than-5 exclusion, alphabetical tie breaks, and separate rankings for each sex apply to every snapshot year as they do to 2025; see the data guide and the ranks-and-counts guide.
  • No labels. The site reports a name's rank and count in each snapshot year and stops there.

Frequently asked questions

Why is each decade era a single year rather than ten?

Because every rank on this site is the SSA's own rank within one sex for one year. The committed decade file holds one SSA year per decade — 1955, 1965, 1975, 1985, 1995, 2005, and 2015 — and nothing in between. Summing ten years would produce positions that appear in no SSA file, so each era is labeled with the year it comes from: "2010s (2015 snapshot)" means names registered in 2015.

How deep does a decade snapshot go?

Exactly 200 names per sex. In 1955 the boys' list ends at #200 with Harvey (1,289 births) and the girls' with Lydia (1,585); the 2025 list is deeper, at 1,000 per sex. Anything below rank 200 in a snapshot year is outside the committed depth.

Why does the "Uncommon" tier return nothing for a decade era?

The "Uncommon" tier is ranks 501–1,000, and a snapshot stops at rank 200, so no name in any decade era can satisfy it. The generator reports that as an empty result instead of substituting other names. The "Less common" tier (ranks 101–500) is only partly covered — ranks 101–200 — and in the 1955 snapshot it holds 100 names per sex.

Was the #1 name the same in every snapshot?

For boys, 3 different names held #1 across the 7 snapshots: Michael (1955, 1965, 1975, 1985, and 1995), Jacob (2005), and Noah (2015). For girls, 6 different names held #1: Mary (1955), Lisa (1965), Jennifer (1975), Jessica (1985 and 1995), Emily (2005), and Emma (2015). In the 2025 data the #1 names are Liam (20,818 boys) and Olivia (13,544 girls).

Can I look up a year that is not a snapshot?

Not on this site. The SSA archive publishes one file per birth year, but the committed data holds only 2025 (top 1,000 per sex) and the 7 snapshot years (top 200 per sex). The site states nothing about other years.

Does appearing in all 7 snapshots mean anything beyond the data?

Only what it literally states: the name sat inside the top 200 for its sex in each of 1955, 1965, 1975, 1985, 1995, 2005, and 2015. 43 boy names and 19 girl names meet that test. The site attaches no label to the result.

Source: every name, rank, and count on this page comes from the U.S. Social Security Administration's national baby-names dataset (1955, 1965, 1975, 1985, 1995, 2005, 2015 and 2025 data, from Social Security card applications). It is public-domain U.S. government data; names given fewer than 5 times in a year are excluded by the SSA, spelling variants are counted separately, and the data covers U.S. births only. Full caveats on the methodology page.
