^*Crude rate per 10,000 population and SE, standard error.

^†Rate of child physician office 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 physician office 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%. https://ftp.cdc.gov/pub/Health_Statistics/NCHS/Dataset_Documentation/NAMCS/
