NATIONAL ACCIDENT SAMPLING SYSTEM SAMPLE DESIGN. PHASES 2 AND 3. EXECUTIVE SUMMARY

The report describes the Phase 2 and 3 sample design for the National Accident Sampling System (NASS). It recommends a procedure for the first-stage selection of Primary Sampling Units (PSU's) and the second-stage design for the selection of accidents for investigation. Cost models are developed to estimate the operating characteristics of the NASS. The design features extensive use of stratification and clustering. Controlled probability selection is used to insure geographic dispersion of the 75 recommended investigation sites, including the initial 10 NASS pilot sites.
