Description:In 2021, 140 million emergency department (ED) visits occurred in the United States. During that year, about 4% of children had two or more ED visits in the past 12 months, and 18% of adults had visited the ED in the past 12 months. This report presents characteristics of ED visits by age group, sex, race and ethnicity, insurance, and mentions of COVID-19, using data from the 2021 National Hospital Ambulatory Medical Care Survey (NHAMCS).
