Phase-In of a New Design When a newly redesigned sample is introduced into the ongoing CPS rotation scheme, there are a number of reasons not to discard the old CPS sample one month and replace it with a completely redesigned sample the next month. Since redesigned sample contains different sample areas, new field representatives must be hired. Modifications in survey procedures are usually made for a redesigned sample. These factors can cause discontinuity in estimates if the transition is made at one time. Instead, a gradual transition from the old sample design to the new sample design is undertaken. Beginning in April 2004, the 2000 census-based design was phased in through a series of changes completed in July 2005 (U.S. Department of Labor, 2004). REFERENCES Cahoon, L.

Chapter 4. Preparation of the Sample INTRODUCTION The Current Population Survey (CPS) sample preparation operations have been developed to fulfill the following goals: 1. Implement the sampling procedures described in Chapter 3. 2. Produce virtually complete coverage of the eligible population. 3. Ensure that only a trivial number of households will appear in the CPS sample more than once over the course of a decade, or in more than one of the household surveys conducted by the U. S. Census Bureau. 4. Provide cost-efficient data collection by producing most of the sampling materials needed for both the CPS and other household surveys in a single, integrated operation. The CPS is one of many household surveys conducted on a regular basis by the Census Bureau. Insofar as possible, Census Bureau programs have been designed so that survey materials, survey procedures, personnel, and facilities can be used by as many surveys as possible. Sharing personnel and sampling material among a number of programs yields a number of benefits. For example, training costs are reduced when CPS field representatives are employed on non-CPS activities because the sampling materials, listing and coverage instructions, and, to a lesser extent, questionnaire content are similar for a number of different programs. In addition, sharing sampling materials helps ensure that respondents will be in only one sample. The postsampling codes described in Chapter 3 identify, among other information, the sample cases that are scheduled to be interviewed for the first time in each month of the decade and indicate the types of materials (maps, listing of addresses, etc.) needed by the census field representative to locate the sample addresses. This chapter describes how these materials are put together. The next section is an overview, while subsequent sections provide a more in-depth description of the CPS sample preparation. The successful completion of the CPS data collection rests on the combined efforts of headquarters and regional staff. Census Bureau headquarters are located in the Washington, DC, area. Staff at headquarters coordinate Current Population Survey TP66 U.S. Bureau of Labor Statistics and U.S. Census Bureau CPS functions ranging from sample design, sample selection, and resolution of subject matter issues to administration of the interviewing staffs maintained under the 12 regional offices, and data processing. Census Bureau staff located in Jeffersonville, IN, also participate in CPS planning and administration. Their responsibilities include preparation and dissemination of interviewing materials, such as maps and segment folders. The regional offices coordinate the interview activities of the interviewing staff. Monthly sample preparation of the CPS has three major components: 1. Identifying addresses. 2. Listing living quarters. 3. Assigning sample to field representatives. The within-PSU sample described in Chapter 3 is selected from four distinct sampling frames, not all of which consist of specific addresses. Since the field representatives need to know the exact location of the households or group quarters they are going to interview, much of sample preparation involves the conversion of selected sample information (e.g., maps, lists of building permits) to a set of addresses. This conversion is described below. Address Identification in the Unit Frame About 80 percent of the CPS sample is selected from the unit frame. The unit frame sample is selected from a 2000 census file that contains the information necessary for within-PSU sample selection, but does not contain address information. The address information from the 2000 census is stored in a separate file. The addresses of unit segments are obtained by matching the file of 2000 census information to the file containing the associated 2000 census addresses. This is a one-time operation for the entire unit sample and is performed at headquarters. If the addresses are thought to be incomplete (missing a house number or street name), the 2000 census information is reviewed in an attempt to complete the address before sending it to the field representative for interview. In sampling operations, this facilitates the formation of clusters of about 4 housing units, called Ultimate Sampling Units (USUs), as described in Chapter 3. Address Identification in the Area Frame About 12 percent of the CPS sample is selected from the area frame. Measures of expected four housing units are selected during within-PSU sampling instead of individual Preparation of the Sample 4–1
