Compound Signal Status
No compound signal at the 70th-percentile threshold
Lake County, California does not show a compound signal, but its disease burden score of 68 (68th percentile nationally) is notably above the median. This reflects elevated chronic disease prevalence across respiratory, cardiovascular, oncology, and behavioral health conditions. 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.
