†Rate of child hospital inpatient stays was calculated using the weighted number of visits for children aged 0-17 years and dividing it by the civilian non-institutionalized population for children aged 0-17 years per 10,000.

•Rate of adult hospital visits was calculated using the weighted number of visits for adults aged 18+ years divided by the civilian non-institutionalized population for adults aged 18+ years per 10,000.

^¶Rate of MSA hospital inpatient stays was calculated by combining the weighted number of visits for large central metro, large fringe metro (suburbs), medium and small metro categories and dividing it by the civilian non-institutionalized population for MSA per 10,000.Rate of non-MSA hospital inpatient stays was calculated using the weighted number of visits for the micropolitan and noncore (rural) category and dividing it by the civilian non-institutionalized population for non- MSA per 10,000.
