Reading the field
The halo is mid-pack to small by raw 5-year gain (rank 40 of 69). Demographically the halo reads as family-heavy, affluent (23% Hispanic, 25% under 18, median income $111,621). Most of that growth is concentrated in Williamson County (rural), which alone added 4,851 of the halo's 2,589 new residents — keep that geography in view when planning outreach.

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.
