Incorporates NCEI-designated Billion-Dollar Disasters only
Significant interaction between exposure and race (Wald interaction test P < 0.05)
Linear Regression Test for Trend, P < 0.05
For each participant, a score of one was assigned if they were categorized in the top quartile for each individual exposure parameter of severity: fatalities per capita, injuries per capita, property losses per capita, crop losses per capita. Level 0 = score of 0, Level 1 = scores of 1-2, Level 2 = scores of 3-4
Values of $4 million were assigned to each fatality and $600,000 to each injury. Dollar amounts for fatalities per capita, injuries per capita, property losses per capita and crop losses per capita were added together, and participants were categorized into quartiles per losses in dollar amounts.
