Quarterly satellite-derived activity at candidate market locations, detected and measured via the Market Activity Index (MAI) method described in Doran, Boehnke & Krusell (2024). Data source: MAI replication package.
Circle color/size = activity index for the selected quarter (mean across satellite images observed that quarter). ~0 = typical non-market-day baseline · ~100 = typical market-day activity for that market/year. Click a circle for details.
Squares = ACLED conflict events in that quarter. Each market's popup also plots nearby conflict counts against its activity history.
Zoomed out, markets are summarized as hexagons (~25 km across) colored by the mean activity index of the markets inside. Zoom in past level 8 to reveal the individual market points underneath. Conflict squares stay visible on top at every zoom.
The purple choropleth is measles-vaccination (MCV1) coverage by admin-2 zone from the 2024-25 EDHS (children 12-23 mo) — a single 2024-25 snapshot, so it does not change with the slider. Darker = lower coverage. Click a zone for its vaccination, market, and conflict summary.
