The aggregated data set

The aggregated data set contains data about each site, aggregated across expert respondents (some redaction applies); one row of data per site. Many of the variable names in this data set are similar to those in the respondent-level data, but with \"_mean\" appended to the end to indicate that it is the mean response across all respondents for a given site. This dataset contains some composite variables that are unavailable in the other data set, but because these data are aggregated, any information about specific experts or from text/open-ended questions are not included. Composite variables were computed based on the full (non-redacted) data set, and thus cannot be reproduced perfectly from the redacted respondent-level data set.
