Part B - Collections of Information Employing Statistical Methods
Question 1. Universe and Respondent Selection
The Basic CPS universe is 114 million households. From the universe of 114
million, we select a sample of approximately 60,500 households. With the SCHIP
general expansion, this increased to 72,000 households each month. Of these,
approximately 59,000 households will be eligible for interview; and we will
actually interview approximately 55,000 households.
The ASEC sample expands upon the Basic CPS sample by adding select
households. Approximately 6,000 Hispanic households interviewed in the
previous November CPS will be added. We expect to interview approximately
4,500 of these households. Additionally, we will add approximately 8,800
minority and White (with children) households that were interviewed in
November. We expect to interview about 6,500 of these households. Finally, we
will conduct the ASEC to selected minority and White (with children) households
during February and April. These households will be “borrowed” from the
February outgoing and the April incoming rotation groups. We expect to select
approximately 12,800 such households, with about 12,000 actually being
interviewed. This brings us to a total of approximately 78,000 households planned
for interview in fiscal year 2019.
We use a household respondent to answer the supplement items for all household
members 15 years of age or older. The response rate for the ASEC averages 85
percent.
Question 2. Procedures for Collecting Information
This is a supplemental survey associated with the CPS. Attachment B gives an
overview of the CPS sample, design, weighting methodology, and response rates.
The statistical properties of these supplemental items will fall within those
associated with the CPS itself.
Question 3. Methods to Maximize Response
Response rates and data accuracy for the CPS are maintained at high levels
through computer edits, interviewer instruction and training, and close monitoring
of the data. Refer to "Overview of CPS Design and Methodology," item 5, for a
discussion of CPS nonresponse (Attachment B).

2
Some amount of allocation for item nonresponse is done within the ASEC
supplement for eligible people. Item nonresponse rates range from less than
2 percent for the work experience items to more than 40 percent for some of the
income items, such as interest and dividends. For the cases eligible for the 2017
ASEC, the basic CPS household-level nonresponse rate was 13.5 percent. The
household-level nonresponse rate for the ASEC was an additional 14.0 percent.
These two non-response rates lead to a combined supplement nonresponse rate of
25.6 percent.
Question 4. Tests of Procedures or Methods
There are currently no methodological or questionnaire tests in progress.
