About the project
Why this exists.
One Hundred Years is an independent research and visualization project. Each issue takes a single dataset — one that spans at least a century of American life — and asks what patterns become visible only at that scale.
The project is built by one person. There is no newsroom, no institution, no funding. Every dataset is public. Every methodology is published. Every line of code is open.

Methodology
How the analysis works.
M1Station Anomaly Engine
Per-station daily anomalies computed against a 1901–2000 baseline. Each station scored against its own historical distribution. No interpolation between stations.
Name frequency time series modeled as rise-peak-decay curves. Half-life extraction, contagion modeling, and trigger event detection via changepoint analysis.
Used in · The Given
Each issue publishes its own methodology tab with full technical detail, known limitations, and confidence ratings.
