Nebraska Annual Social Indicators Survey, 1990

Data Archive > U.S. Surveys > General Population > Local/Regional > Others > Summary

This project aims to survey quality of life in the state of Nebraska, covering topics such as the environment, housing, health, recreation, occupation, education, family life, among others. A set of core questions are repeated each year, and additional questions are purchased by those interested in gathering additional data. It is conducted by the Bureau of Sociological Research of the University of Nebraska-Lincoln in collaboration with state agencies and educational and research organizations.
Data File
Cases: 2,042
Variables: 634
Unweighted samples are close to the 1980 U.S. Census data, but deviations included an overrepresentation of the southeast region and underrepresentation of the Omaha and South Central areas. The sample is furthermore fairly close in age distribution, but has an overrepresentation of women.

To produce a representative sample of individuals 19 and over living in households in the state, use PWEIGHT. This variable contains adjustments for region, sex, and age bias and compensates for differential probability of selection of respondents within households with varying numbers of adults present.

When analyzing at the household level, such as number of households where income is below a certain level, use the variable HWEIGHT. This variable contains the same adjustments for region, sex, and age, but does not make adjustments for number of adults in the household.

Sampling Procedures
Random digit dialing (RDD) was used to gain a representative sample of noninstitutionalized persons in households with telephones in the state of Nebraska. Persons under 19 years of age, persons in custodial institutions, persons in group living quarters, persons on military reservations, and transient visitors were excluded from this sample.

To ensure a random sample of persons rather than households, selection of eligible respondents within a household was based upon a random selection table printed on the label containing the telephone number to be dialed. Each table noted a randomly assigned respondent number for each household size; thus, if a household had three eligible respondents, one-third of the selection tables called for interviewing the first adult, one-third called for interviewing the second adult, and one-third called for interviewing the third adult. However, because the probability of inclusion in the sample is smaller in larger households, a weighting procedure is used to account for this bias.
