National Health Interview Survey, 1993

The purpose of the National Health Interview Survey (NHIS)
is to obtain information about the amount and the distribution of
illness, its effects in terms of disability and chronic impairments,
and the kinds of health services people receive. Household Record
variables in this data collection include type of living quarters, size
of family, number of families in the household, and geographic
location. Person Record variables include sex, age, race, marital
status, veteran status, education, income, industry and occupation
codes, and limitations on activity. The Condition Record file contains
information for each reported health condition, with specifics on
injury and accident reports. The Doctor Visit Record file documents
doctor visits within the time period and identifies acute or chronic
conditions. The Hospital Episode Record file contains all recalled
accounts of hospitalizations in the 12-month period.
