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.The ARDA has added five additional variables to the original data set to enhance the users' experience on our site.
Data File
Cases: 1221Variables: 309
Weight Variable: PWATE, HWATE
Although unweighted samples are close to the 1980 U.S. Census data, the southeast region and females are overrepresented in the telephone survey, consistent with other NASIS years, and both the telephone and mail samples underestimate persons under 35 years of age and overestimate persons over 65 years of age.
To produce a representative sample of individuals 18 and over living in households in the state, use PWATE. This variable contains adjustments for age and sex 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 HWATE. This variable contains an adjustment for region.

Telephone interview, mail surveySampling Procedures
For telephone interviews, 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 18 years of age, persons in custodial institutions, persons in group living quarters, persons on military reservations, and transient visitors were excluded from this sample. Students in an Advance Research Methodology class and professional interviewers hired by the Bureau of Sociological Research conducted the interviews.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.
Mail surveys were sent to one out of every 571 households listed in Nebraska telephone directories. A template method was used to select these households from pages at random, totaling 1048 addresses. Questionnaires were mailed to these addresses with a postage-paid business reply envelope and cover letter explaining the purposes and sponsor of the study. To increase response rate, a total of four mailings were sent.
