Data for this chart pack come from a variety of nationally-representative datasets, including the 2015 Current Population Survey, March Annual Social and Economic Supplement, the 2014 Behavioral Risk Factor Surveillance System, the 2014 National Health Interview Survey, the 2011-2014 National Health and Nutrition Examination Survey, and the 2014 National Survey on Drug Use and Health, as well as from several online reports and databases, including the 2014 Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report (MMWR) on vaccination coverage, the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) Atlas, the United States Cancer Statistics Incidence and Mortality Web-based Report, the 2014 CDC Natality Public Use File, and the CDC WONDER online database.

Unless otherwise noted, race/ethnicity was categorized by non-Hispanic White (White), non-Hispanic Asian (Asian), Hispanic, non-Hispanic Black (Black), non-Hispanic American Indian and Alaska Native (AIAN), and non-Hispanic Native Hawaiian or Other Pacific Islander (NHOPI). Asian and NHOPI race categories were combined when they could not be separately identified. “N/A” indicates that data for a racial/ethnic group could not be separated from an “other” category in that data source or cases in which point estimates have relative standard errors greater than 30 and do not meet minimum standards for statistical reliability. Non-Hispanic Whites were the reference group for all significance testing.
