Rate of child emergency department visits 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 emergency department 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.

Estimate is suppressed because relative standard error (RSE) of the estimate is >30%.
