Peak popularity prediction
Trending toward a peak rank around #764 (95% range 619–1,050) in 2035.
Projects the trend forward, then converts share into rank using this year's popularity distribution.
This forecasts Quincy's share of births by fitting a damped-trend model to its last 143 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 current trend is projected to set a new all-time high within the next 10 years. 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.
Births have grown roughly 3% a year on average over the last 5 years, and Quincy hasn't yet revisited its historic peak.
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.Quincy isn't currently in the Top 100 tier. Estimated chance of entering it in the forecast window: 0%.
If Quincy 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.
