ORB International Weighting Consultation

CSR consulted with ORB on sample design for multi-stage area probability samples to be drawn in three African countries. After data were collected by local vendors on behalf of ORB, CSR applied base weights and post-stratification weights (using iterative rim weighting, also known as raking methods) to results from each country. Final, weighted data files were delivered to ORB, for delivery to the project sponsor.
