Research note
Why trend pages matter
This page answers a different question than the static city ranking: not just where violent crime is highest today, but which city trend lines are moving most.
Statewide directional ranking showing which supported Iowa cities are improving or worsening fastest on violent crime, using the current coarse statewide safety context with low-base safeguards so the order stays readable instead of sensational.
Ranked rows are precomputed and served as static HTML from R2.

This page answers a different question than the static city ranking: not just where violent crime is highest today, but which city trend lines are moving most.
Treat the page as a directional screen, then open the linked city brief to inspect current level, neighborhood spread, and broader local conditions. When the starting period is unusually small, the page switches to absolute-rate change instead of a misleading percentage.
