Climatic predictions for the Illinois region are for extreme heat, heavy rainfall, and flashfloods, which suggest that
heat-related illness and waterborne disease would be salient public-health concerns. Data analysis reveals that maximum
temperatures in the nonmetro during 1999-2021 have increased at an annual compound growth rate of 0.32%. Specifically,
of the 12,883 deaths that occurred during the summer months of 1999 to 2021, an estimated 5,926 to 6,828 of the deaths
could be attributed to heat-related mortality. Ceteris paribus, heat-related mortality is expected to grow at an ACGR of
1.6% and reach 6,841 to 7,884 deaths by 2030.
