  "alt": "A nine by nine grid of correlations between the tract prevalence of nine chronic conditions. Stroke, diabetes, COPD, coronary heart disease and arthritis correlate strongly and positively with one another. Asthma and obesity correlate moderately with those conditions and with each other. Cancer and depression have the weakest correlations with the other conditions, and cancer is slightly negative against asthma and obesity.",
  "caption": "Cells toward the teal end of the key are positive correlations and cells toward the brown end negative ones. The strongest cells join stroke, diabetes, COPD, heart disease and arthritis, and the weakest cells all involve cancer or depression, with cancer negative against asthma and obesity. Each cell is the correlation between two conditions across tracts, weighted by adults, with a 95% interval from a bootstrap over counties. Rows and columns share one order that places similar conditions together.",

    "PLACES values are modeled estimates. A model fitted to survey responses is applied to each tract's census population, so every condition's estimate depends on the same age, sex, race, ethnicity and education inputs and on county and state effects, and correlations across tracts are partly built in. The tract file carries no intervals, and the intervals shown here come from a bootstrap over counties.",
    "The diagonal is one by construction and has no interval. Values are crude prevalence among adults, not adjusted for age, so the age mix of a tract moves them.",
    "The nine conditions are the PLACES health outcome measures that cover all adults and have an estimate in every state. High blood pressure and high cholesterol are left out because the 2024 tract release has no estimate of either for {fact:bp_florida} Florida tracts; outside Florida the mean correlation of high blood pressure with the nine is {fact:bp_r}."
