  "alt": "A grouped bar chart of the share of tracts by the number of high conditions, from none to all nine. The observed bars are tallest at none, fall steeply over the first few counts, are nearly level across the middle and high counts and fall again at the last two, and they stay well above the benchmark bars at the high counts. The benchmark bars for independent conditions peak at a low count and shrink to almost nothing toward the right.",
  "caption": "The observed bars are tallest at no high conditions and form a long right tail, while the benchmark bars peak at a low count and vanish toward the right. A tract is high on a condition when its prevalence is in the highest {fact:cut_pct} of tracts. The observed bars are shares of tracts with a 95% interval from a bootstrap over counties; the benchmark applies each condition's observed share of high tracts as if the conditions were unrelated across tracts.",

    "The count is a count of tract prevalences above a cutoff, not a count of conditions in any person. 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.",
    "Tied values fall on one side of the cutoff, so the share of tracts that is high on one condition runs from {fact:high_share_min} to {fact:high_share_max}. The benchmark is a Poisson-binomial distribution with those shares. Shares of adults living in these tracts differ from shares of tracts (for example {fact:none_share_w} of adults live in tracts that are high on none)."
