Compound Signal Status
No compound signal at the 70th-percentile threshold
Tuolumne County, California does not show a compound signal, but its environmental risk score of 61 (61st percentile nationally) is notably above the median. This reflects elevated air quality, water contamination, toxic releases, or climate exposure. 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.
