Monetary values are given in 2015 US dollars. The numbers of people with asthma were estimated by the use of personal weights provided in the 2008-2013 Medical Expenditure Panel Survey samples. Confidence intervals were estimated assuming that prevalence and per-person medical cost are independent random variables.
