Names That Died — How the 20th-Century Top Names Faded by 2024

Key Findings

Each finding verifiable from the SSA dataset. "Died" = ranked outside top 500 in 2025.

The Killing Decades — Where the Casualties Cluster

For each decade between 1900 and 1979, this is the share of that decade's top-20 girls' names that are now ranked outside the top 500 (or absent from the SSA record entirely) in 2025.

Boys: a different story

The boys' table reads as the photonegative of the girls'. The 1900s and 1910s have more casualties than the post-1930s — but those casualties are largely Edwardian-flavored names (Earl, Clarence, Howard, Ralph) from a different cultural register. From the 1930s onward, boys' top-20 names die at a fraction of the girls' rate. The 1970s top-20 boys' list has just 1 casualty out of 20.

Side by Side — 1950s Top 20, Then and Now

The single starkest demonstration of the asymmetry. Same decade. Same top-20 cutoff. Different fate.

Look at the colors: the girls' list is almost entirely red (dead). The boys' list is mostly green (alive). Same decade. Same families giving these names. Same culture. But by 2024, only one of the girls' top-20 still ranks in the top 200, while twelve of the boys' top-20 do. The pattern is not subtle and not new — but seeing both lists side-by-side makes the structural difference unavoidable.

The Trajectories — Six Names That Defined Mid-Century Girls' Naming

Year-by-year rank for six representative names from the post-war girls' canon. Names off the top 100 in a given year are clipped.

The shapes are remarkably similar to each other: a sharp climb to the top 10 (or top 1), a plateau lasting 10–15 years, then an equally sharp descent. Linda climbed in the 1940s, peaked at #1 1947–1952, then fell continuously for 70 years. Jennifer climbed in the late 1960s, held #1 from 1970–1984, then began the same descent. The mathematical shape is recognizable in advance: a girls' name peaks, plateaus, and falls. It is not a sustainable steady-state.

The Longest Falls

The 15 names with the largest individual fall from peak rank (1900–1979) to 2025 rank.

The pattern in the longest-falls list is clear: it is overwhelmingly girls' names from the 1940s and 1950s. Where boys' names appear at all in this list, they tend to be names whose cultural register (working-class Edwardian, mid-century military) has become specifically dated.

Why Boys' Names Persist and Girls' Names Don't

The dataset doesn't explain causation, but it constrains the explanations. Three factors are consistent with what the data shows:

• The "biblical canon" effect. Boys' names have a longer-tenured set of names rooted in religious, royal, and historical traditions — John, James, William, Michael, Robert, David — that have been in continuous use for centuries. New parents picking these names are choosing tradition; the names don't get associated with any single decade, so they don't trigger generational rejection.
• Generational over-saturation triggers rejection. When a girls' name reaches very high market share (5%+) in a single decade, it becomes the "mother's generation" name for the next cohort and gets actively avoided. The data shows the highest-peaked girls' names (Linda 8.5% in 1947, Jennifer 4% in the 1970s) experience the steepest subsequent falls. Boys' names rarely concentrate at that level.
• Different cultural function. Sociolinguists have observed for decades that girls' names are treated more as fashion items and boys' names more as family-tradition markers in Western naming conventions. A girls' name's job is partly to feel "current"; a boys' name's job is partly to feel "established." These differing job descriptions produce different decay rates.

What This Predicts for 2024 Names

Three implications follow from the historical data:

• Today's #1 girls' names will fade within 30 years. Every #1 girls' name in the dataset has eventually fallen out of the top 100 within 30–60 years of its #1 reign — every single one without exception. Olivia is currently at peak; under the historical pattern, Olivia will likely begin its descent within the 2030s.
• The 1980s/1990s girls' names are the next to die. Names like Jessica, Ashley, Amanda, Stephanie, Heather, Nicole — the dominant 1980s/90s cohort — are currently in their decline phase. By the 2030s/2040s these will read as "mother-generation" names and accelerate their fall.
• Today's top boys' names will mostly survive. Liam, Michael, William, James, Henry — these have the structural patterns of names that persist. Even Liam, currently at peak, is unlikely to crash the way Lisa or Jennifer did. Liam's 2010s ascent looks more like Michael's 1950s ascent than Lisa's 1960s ascent.
