SUPPORTING STATEMENT

B. COLLECTION OF INFORMATION EMPLOYING STATISTICAL METHODS

1. Respondent Universe

The May 2012 supplement will be conducted in conjunction with the CPS, for which the universe is 111 million households. From this universe, the Census Bureau selects a sample of approximately 72,000 households each month, of which approximately 60,000 households are eligible for interviews. The Census Bureau actually interviews about 55,000 households each month. The items in the supplement are asked, as appropriate, for members of the households.

2. Procedures for Collecting Information

This is a supplemental survey associated with the CPS. The statistical properties of these supplemental items will fall within those associated with the CPS itself. For additional information on the design of and preparation of the CPS sample, see Chapters 3 and 4 of Technical Paper 66. Weighting is discussed in Chapter 10. Technical Paper 66 is available at http://www.census.gov/prod/2006pubs/tp-66.pdf.

3. Methods to Maximize Response

Response rates and data accuracy for the CPS are maintained at high levels through internal consistency edits in the computerized instrument, interviewer instructions, training, and close monitoring of these data. For additional information, see Chapter 7 and Appendix D of Technical Paper 66, available at http://www.census.gov/prod/2006pubs/tp-66.pdf.

4. Testing of Procedures

The development of the CPS Disability Supplement began with a public outreach effort coordinated by the US Department of Labor’s Office of Disability Employment Policy (ODEP) and the Bureau of Labor Statistics (BLS) and conducted by Economic Systems, Incorporated. The questions that resulted from the outreach were reviewed and pared down based on the focus of the project and the size limitations of the supplement. This question set was then subjected to two rounds of cognitive testing in which the effectiveness of each question was examined (Attachments F and G).
