Four principles
Most “crime maps” are just heatmaps of arrest counts. We built this because we wanted something that could tell us whether last month was actually different — and where.
Trend, not totals
Counts mislead. We index on month-over-month change, seasonality, and direction — what's actually moving.
Anomaly-first
Statistical signals surface unusual movement before you notice it. No more reading rank-order tables.
Neighborhood scale
City totals hide everything. We aggregate to neighborhoods so the story is locally legible.
Methodology open
Every signal, every forecast, every backtest — fully documented. Read the rules; reproduce the numbers.
