B. Collection of Information Employing Statistical Methods
1. Universe and Respondent Selection
We conduct the HVS in conjunction with the CPS for which the universe is
123 million housing units. We select a sample of approximately 72,000 housing units from this universe each month. We interview a unit for the HVS if it is vacant and intended for year-round occupancy, as determined during the CPS interview. Approximately 7,000 units in the CPS sample meet these criteria each month; these units represent about 13.7 million year-round vacant units (in 2013) across the United States each month. Based on past experience, we expect a response rate of approximately 96.7 percent.
2. Procedures for Collecting Information
Attachment G gives an overview of the CPS sample design and weighting methodology. The HVS weighting procedure is similar to that used by the CPS. The basic weight is the reciprocal of the probability of selection of the unit in the CPS sample. First- and second-stage adjustments similar to those described in Attachment G for the CPS are made to the HVS basic weight. The first-stage adjustment is made to bring the sample estimates into agreement with distributions for vacant units at the state levels as measured in the 2010 decennial census. The second-stage adjustment inflates the weight to account for undercoverage in the CPS sample.
Historically, the coefficient of variation for vacant rental units was approximately 2.8 and 5.5 percent annually at the national and regional levels respectively. We deem this degree of accuracy sufficient for data analysis and publication purposes.
3. Methods to Maximize Response
We maintain response rates and data accuracy for the CPS at high levels through interviewer instruction and training and close monitoring of data output. (Refer to paragraph 5 of Attachment G for a discussion of the CPS nonresponse.) Allocation for item nonresponse is done within the HVS eligible households.
4. Tests of Procedures or Methods
Tests of procedures and methods are not required since we have conducted the HVS for 58 years.
