SUPPORTING STATEMENT

B. Collection of Information Employing Statistical Methods

1. Universe and Respondent Burden

The January 2008 supplement will be conducted in conjunction with the CPS, for which the universe is 111 million households. From this universe, we select a sample of approximately 72,000 households each month, of which approximately 60,000 households are eligible for interviews. About 55,000 households are actually interviewed 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 January 2008 CPS. The statistical properties of these supplemental items will fall within those associated with the CPS itself. (Attachment G)

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.

4. Testing of Procedures

Testing of these supplemental items was not required since the same survey was conducted in January 2004 and January 2006. Attachment H discusses the reliability of the estimates produced from the January 2006 Displaced Worker, Job Tenure, and Occupational Mobility supplement.
