Click a block group to inspect it. Drag to pan; scroll or use + / − to zoom. Keyboard: Tab into the map, arrow keys to pan, Home to reset. Tab again to reach block groups; arrow keys move between them, Enter or Space selects.

Selected block group

Choose a block group on the map. A group label describes this partition only.

Groups in this partition

Each number is a group ID, not a rank. Counts are block groups.

What the scores mean

Louvain uses weighted edges; Leiden uses unweighted edges.

Their modularity scores measure different objectives and should not be ranked against each other. Graph edges connect similar demographics, not necessarily adjacent places.

I treated negative ACS estimate codes as missing before calculating rates, then median-imputed missing features. The map shows those corrected runs.
