Columns (1) to (5) represents marginal effects from five separate logistic regressions. Standard errors are clustered at the county level in parentheses. State-month is the interaction of state and month dummies to control for local seasonality; county, day-of-year, and year are dummies that control for unobserved differences across counties, days of the year, and year. All regressions control for individual covariates (age and its squared, gender, income, marital status, number of children, education, employment, health plan) as well as average precipitation for the past 30 days. Both sunlight and dewpoint temperature are added as average on previous 30 days. Survey weights are applied. Bin of 60–70°F is omitted as the reference and the dotted line separates temperature cooler/hotter than the reference.
