Nebraska Annual Social Indicators Survey, 2005
SummaryThe 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 2005 NASIS asks questions about outdoor activities, employment, nursing homes, discrimination, and religion.
The ARDA has added five additional variables to the original data set to enhance the users' experience on our site.
Data FileCases: 1807
Weight Variable: PWEIGHT, HWEIGHT
"Two weights are included in the 2005 data archives. The first weight, called PWEIGHT, produces a
representative sample of individuals 19 and over 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 over-19 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." (2005 NASIS Methodology)
