2006 National and State Estimations Civil Rights Data Collection

These files are state and national estimations for the Civil Rights Data Collection.
The 2006 estimations are based on a rolling stratified sample of approximately 6,000 districts
and 60,000 schools, and on reported data from those districts that responded to the survey.
Documentation is available from OCR which describes the procedures used for the estimations,
including weighting of the sample, imputation for item non-response, standard errors, and
quality control procedures. In addition, documentation is available from OCR for estimations
that should be used with caution due to large statistical uncertainty in the estimate,
including factors which contributed to the extent of this statistical uncertainty for the
Civil Rights Data Collection. This hardcopy documentation, available upon request, is
contained in "Civil Rights Data Collection (CRDC) Estimations and Documentation."
