• Summary of rejected FSCPE records:• All 15 were currently on MAF as GQ• No new data added to existing MAF record

Evaluating the FSCPE Results

• FSCPE records had high rate of new addresses good “bang for the buck”

• Low MAF rejection rate = high quality data

• Census ad hoc GQ follow up confirmed high FSCPE quality

• FSCPE verification confirmed high quality
