Survey of Public Participation in the Arts 1982-2012 Combined File [United States]

The data file includes two weight variables: WEIGHT is used when producing estimates for a particular year or comparing years, and WEIGHT_NORMALIXED is used when pooling or combing data across years. The data file also has two variables -- VARSTRAT and VARUNIT --that are included to help people estimate the variance or standard error associated with the estimates. Users are encouraged to see the appendix to the data dictionary (available in PDF as part of this collection) that describes in detail the weighting and variance estimation procedures.
