Compound Signal Status
No compound signal at the 70th-percentile threshold
Fairfield County, South Carolina does not show a compound signal, but its SDOH stress score of 70 (70th percentile nationally) is notably above the median. This reflects elevated social vulnerability including poverty, housing instability, transportation barriers, and insurance gaps. The other dimensions remain below the 70th-percentile compound-signal threshold, so the pattern here is concentrated risk in one area rather than converging multi-dimensional stress.
