Elderly share 65+ — MO polygons (2021)
Vulnerability & census
Share of neighbourhood population aged 65+ — polygon choropleth (preferred over kernel/circle summaries). Use this to see who lives in hotter areas and where social sensitivity is highest.

What it shows
Fill colour from elderly_share (0–1). Tooltip/popup include formatted percentage columns. **Off by default** (toggle with population density for comparison).
Data sources

How it was prepared
