Design and Implementation of the Interview Survey

Sampling Frame and Sample Size for the Interview Survey

The sample for the Interview survey begins with a selection of 91 area-based primary sampling units (PSUs). The PSUs may be individual counties, groups of counties, or “core-based statistical areas” (CBSAs) identified by the Census Bureau. Of these 91 PSUs, 21 are metropolitan CBSAs with over 2.7 million people, while 16 are considered “rural.” The rest fall somewhere in between (Bureau of Labor Statistics, 2012) as indicated in Box 3-2.

Each year the Census Bureau selects approximately 15,000 addresses from these PSUs for contact on the Interview survey using the augmented 2000 Census 100-Percent Detail File. The bureau uses a rotating panel design with sampled households contacted quarterly for five quarters. This process results in a usable sample size of approximately 7,100 interviews per quarter.
