Nebraska Annual Social Indicators Survey, 2011

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

The Nebraska Annual Social Indicators Survey (NASIS) 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. The 2011 NASIS asks questions about water issues, life processes, crime and the criminal justice system, media and television, vacation and travel, physical and social environment, gender and parenthood, personal feelings, and household finances.

Data File
Cases: 906
Variables: 240
Weight Variable: PWEIGHT, HWEIGHT
"Two weights are included in the 2011 NASIS dataset. The first weight, called PWEIGHT, produces a representative sample of individuals 19 and older living in households in the state. PWEIGHT contains an adjustment for the region, sex, and age bias found in the sample and a correction factor to compensate for differential probability of selection of the respondent within households with varying numbers of adults present. To adjust for this difference, weighting procedures are used in the computerized data file to correct for selection probabilities. The resulting sample is of individuals and should be treated as a simple random sample of the 19 and older population. Users of NASIS data requiring a sample of individuals would use the data weighted by the PWEIGHT variable.

"The second weight, HWEIGHT, is used when the information needed is at the household level. For example, if someone was interested in the number of households in which income is below a certain level, then individual weights would not be appropriate. Because some households, as well as individuals, were under-represented in the sample, some adjustment was needed to compensate for this bias. This was done by using the same age-sex-region weights used in the PWEIGHT variable, but removing the weighting component to compensate for the number of adults in the household. Use of HWEIGHT gives an age-adjusted sample of households in the state." (Source: NASIS 2010-2011 Methodology report - see link above)

Department of Sociology at the University of Nebraska-Lincoln, Bureau of Sociological Research, and other state agencies and educational and research organizations
Collection Procedures
The NASIS for 2011 was conducted using a mail survey. Nebraska households with a known postal address were sampled.
Sampling Procedures
"The sample for the 2011 NASIS was purchased from Survey Sampling International, LLC (SSI). A total 2,498 cases were provided to BOSR by SSI on April 7, 2011. The sample was randomly divided into four equal groups. Each of the groups were given different instructions based on age or birthday for which adult in the household was to fill out the survey. The parameters designated to each group asked for the adult in the household age 19 or older who most recently celebrated a birthday, who will next celebrate a birthday, who is the youngest, or who is the oldest." Prior to 2009, the NASIS was administered as a telephone interview." (Source: NASIS 2010-2011 Methodology report - see link above)
