NCIt definition : Since its inception in 1957, the NHIS has been a continuing nationwide sample survey
in which data are collected through personal interviews with household members by
U.S. Bureau of the Census interviewers. Data are used to provide national estimates
on the incidence of acute conditions, the prevalence of chronic conditions and impairments,
