Abbreviation: CI = confidence interval.
* Active epilepsy cases in children are estimated from the current epilepsy prevalence in children (2011–2012 National Survey of Children's Health) and the population of children, accounting for the ratios of family income to poverty thresholds.
† Active epilepsy cases in adults are estimated from the prevalence of active epilepsy (taking medication, having had a seizure in the past year, or both) in adults (2015 National Health Interview Survey) and the population of adults, accounting for the ratios of family income to poverty thresholds. The total population estimates come from the 2014 weighted person counts of the Current Population Survey, 2015 Annual Social and Economic Supplement of the civilian noninstitutionalized population living in houses and military population living in houses.
§ Confidence interval represents only sampling uncertainty from the sampling uncertainties in the prevalence estimates and in the state-specific and age-specific ratios of family income to poverty thresholds.
