North Dakota Health Insurance Survey, 1998 (ICPSR 3313)

Principal Investigator(s): Knudson-Buresh, Alana, North Dakota Department of Health


The objectives of this survey were (1) to determine who the uninsured were in North Dakota, (2) to show how the 1997 flood affected Grand Forks and other Red River Valley residents, (3) to provide information to help government and private industry respond to the needs of disaster survivors, and (4) to update the results of the 1993 health care survey conducted under the State Initiatives in Health Care Reform Program (ROBERT WOOD JOHNSON FOUNDATION EMPLOYER HEALTH INSURANCE SURVEY, 1993 [ICPSR 6908] and ROBERT WOOD JOHNSON FOUNDATION FAMILY HEALTH INSURANCE SURVEY, 1993 [ICPSR 6894]). The interview collected information on household composition, health insurance status for each member of the household, impact of the flood, and demographic characteristics such as employment status, age, sex, and income. All households with at least one uninsured individual were administered a needs assessment module to collect more detailed information on health care coverage, utilization, and needs, as well as additional demographic information. Data are presented at the person level and the "family insurance unit" (FIU) level, a grouping typically used by insurance carriers. A FIU comprises an adult household member, his or her spouse, if any, and any dependent children 0-17 years of age, or 18-22 years of age if unmarried full-time students.
