Compare Hadley →Living-age distribution
The median living Hadley is 10. If you meet a Hadley, there's about a 70% chance they're between 4 and 17 years old.
Popularity arc
Peak Hadley: 2018. Down 13% from peak.
Projected: the dashed 10-year forecast (Holt damped-trend exponential smoothing, fit to recent years), with a shaded 95% interval.
Gender balance
3.1% male, 96.9% female.
Rarity
Hadley ranks #1,121 out of 105,966 names ever recorded by the SSA.
Geographic fingerprint
Hadleys are 1.2x more common in the Midwest than the national average.
Predictive modeling
Three statistical models, all fit to Hadley's own SSA history plus the historical behavior of every other name in the dataset.
Peak popularity prediction
Hadley's modeled peak was #238 in 2014 — its trend isn't projected to beat that.
Projects the trend forward, then converts share into rank using this year's popularity distribution.
This forecasts Hadley's share of births by fitting a damped-trend model to its last 119 years of data and projecting 10 years forward with a widening uncertainty band. Each projected share is then translated into a rank by comparing it against 2025's actual name-popularity distribution — so the model implicitly assumes the overall shape of that distribution doesn't shift much over the forecast window. Its trend is projected to stay below its historic best over the next 10 years, so the model treats 2014 as its peak. Milestone probabilities come from how much of each year's uncertainty band clears that milestone's rank, combined across years as if they were independent — which slightly overstates the odds for names sitting right at a threshold, since a good year is usually followed by another good year rather than an independent coin flip.Name life-cycle stage
A rule-based classifier over recent growth, momentum, and peak proximity.
Hadley is holding within 13% of its all-time peak share and growth has flattened out — it's plateaued near the top rather than still climbing or sliding.
Popularity survival model
Once a name reaches a rank tier, how long does it typically stay there before falling out?
Built from a Kaplan-Meier survival curve: every historical run any name has ever had above this tier, with runs still ongoing today counted as still in progress rather than as an exit.Hadley isn't currently in the Top 100 tier. Estimated chance of entering it in the forecast window: 0%.
If Hadley enters Top 100, chance it's still there after:
Names that do enter Top 100 have historically stayed a median of ~19 years. Based on 668 historical Top 100 runs across every name in the dataset.
