SUPPORTING STATEMENT
B. COLLECTION OF INFORMATION EMPLOYING STATISTICAL METHODS
1. Universe and Respondent Selection
We conduct the June Fertility Supplement in conjunction with the CPS, for which the universe is 16 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 interview.
We actually interview about 57,000 households each month. We ask the items in the June supplement, as appropriate, for members of these households. Based on previous response rates for similar questions, we expect the supplement response rate to be approximately 94.7 percent.
2. Procedures for Collecting Information
The Fertility Supplement is a supplemental survey associated with the June CPS. Attachment E gives an overview of the CPS sample design and weighting methodology. The statistical properties of these supplemental items will fall within those associated with the CPS itself.
3. Methods to Maximize Response
We maintain response rates and data accuracy for the CPS at high levels through computer edits, interviewer instruction and training, and close monitoring of these data. (Refer to paragraph 5 of Attachment E for a discussion of the CPS nonresponse.) Some amount of allocation for item nonresponse is done within the June supplement for eligible people.
4. Testing of Procedures
We do not require testing of procedures and methods given that we have conducted the June Fertility Supplement since 1971. Attachment F discusses the reliability of estimates produced by the June 2008 supplement.
