Reading this briefing
A halo is every census tract whose population-weighted centroid
sits within 10 straight-line miles of the church location.
"Pop-weighted income" averages tract median household income, weighting
each tract by its population. Tracts where ACS suppresses median income
(small samples) are excluded from this average.
The same tract can sit inside multiple churches' halos — overlapping
halos describe shared mission fields, not exclusive territory.
