PDQ:

  • Is a stand-alone data capture tool, used in the

Census 2010 Decennial Response Integration System (DRIS) to measure data capture quality

  • Uses different OMR & OCR software from the

Census DRIS data capture system

  • Independently evaluated over 800,000 sampled

DRIS form images and production data in near- real time

  • Reported on the mark recognition, character

recognition, and keying data accuracy of the Census 2010 DRIS data capture system

PDQ Was Important to Census

1. PDQ provided an independent measure of DRIS data quality in a timely manner 2. PDQ provided the capability to detect systemic anomalies in the DRIS production system, such as an accuracy shortfall due to a processing or template definition problem 3. PDQ provided precise evidence to Census that the Prime contractor (LM) met their Service Level Agreements (SLAs)

Conclusions

  • PDQ was used very successfully for

2010 Census data capture to measure Production Data Quality

  • It could be applied to any production

forms processing system to do a data quality audit or to guide continuous improvement

  • This technology is extensible to other

types of classifier systems, such as Record Linkage
