Data

The data consists of variables that assess the relationship between the county-level measure of SDoH and county-level fatal crash counts among geriatric and non-geriatric road users. We pooled data from the Fatality Analysis Reporting System and limited our analyses to the 3,108 contiguous US counties. The outcome measures were county-level fatal crash counts involving (1) geriatric (65 years and older) road users, (2) non-geriatric road users, and (3) the general population. The predictor variable was the Multidimensional Deprivation Index (MDI), a three-level categorical variable defined as: very highly deprived, highly deprived, and average-to-low deprivation.
