IR= incidence rate per 100,000 population.
aIncidence rates (IR) are calculated per 100,000 population. Population data are projected population from Texas Demographic Center’s Texas Populations Projections Program; 2020 and 2019 population projections were updated March 2022, and 2018 & earlier population projections were from the prior version.
