Reading the field
The halo is mid-pack to small by raw 5-year gain (rank 24 of 69). Growth is healthy (19% in five years) — the field is expanding, not flat. Demographically the halo reads as majority-Hispanic (46% Hispanic, 17% under 18, median income $66,281). Posture: bilingual reach is a fit here given the demographic trajectory. Worth checking against the Lens C / D priority briefing for ministry-siting overlap.

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.
