Compound Signal Status
No compound signal at the 70th-percentile threshold
Clay County, South Dakota does not show a compound signal, but its provider gap score of 70 (70th percentile nationally) is notably above the median. This reflects elevated healthcare specialist shortages relative to population need. 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.
