2Crude rate per 10,000 population.
3Rate was calculated using the weighted number of visits for children aged 0-17 years divided by the civilian non-institutionalized population (for emergency department visit rate) or resident population (for hospitalization rate) for children aged 0-17 years and multiplied by 10,000.
4Rate was calculated using the weighted number of visits for adults aged 18+ years divided by the civilian non-institutionalized population (for emergency department visit rate) or resident population (for hospitalization rate) for adults aged 18+ years and multiplied by 10,000.
