The U.S. Census Bureau is moving forward with its plans for a pivotal field test in 2027 related to the Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC). This initiative, formally announced in a recent Federal Register notice, represents a significant step in modernizing the collection of some of the nation's most critical economic and social data. The test, scheduled from January to May 2027, will primarily focus on evaluating the effectiveness and comparability of an internet self-response (ISR) mode for the ASEC, a shift from the longstanding computer-assisted personal interviewing (CAPI) approach.
The Significance of CPS and ASEC
Since 1942, the CPS has been the authoritative source for government statistics on employment and unemployment, a joint endeavor between the Bureau of Labor Statistics (BLS) and the Census Bureau. Its scope extends to comprehensive labor force information for the civilian noninstitutional population, encompassing employment status, hours worked, job search activities, earnings, and occupational classifications.
The ASEC, administered annually in February, March, and April as a supplement to the CPS, delves deeper into areas such as work experience, personal income, noncash benefits, and health insurance coverage. It is the official basis for national poverty estimates, determined in accordance with the Office of Management and Budget's Statistical Policy Directive 14. Furthermore, the ASEC yields other crucial national figures, including real median household income and the count of individuals without health insurance coverage. The integrity and consistency of these data points are paramount for policymaking, economic analysis, and public understanding of societal trends.
Goals of the 2027 Field Test
The 2027 Field Test marks the third in a series of major evaluations, following earlier tests in 2025 and 2026. Its ultimate objective is to align the ASEC with planned phase-in changes to the main CPS, anticipated between 2027 and 2028, with the full ASEC transition projected for 2029.
Two primary goals underscore the 2027 test:
-
Introducing a Self-Response Mode: This test is the inaugural attempt to administer the ASEC supplement as a self-response instrument. Historically, ASEC data has been collected by Census field interviewers via in-person or telephone interviews using CAPI. To transition to an ISR mode, extensive qualitative research, expert reviews, and smaller-scale tests have been conducted to adapt CAPI question wording into an ISR-appropriate format. The 2027 Field Test offers the first large-scale opportunity to assess the comparability of data collected through CAPI versus ISR.
-
Content Testing: Beyond the mode shift, the field test will also evaluate questionnaire clarity and comparability. Leveraging findings from prior qualitative research, the test will employ a split-path examination, comparing a control version against a test version of ASEC question changes. Given that all ASEC questions will undergo some modifications to suit the self-response format, the test aims to quantify the impact of revised question wording, altered response categories, and redefined underlying constructs on the quality of key ASEC estimates.
Public Engagement and Data Collection Specifics
In accordance with the Paperwork Reduction Act of 1995, the Department of Commerce is soliciting public comments on this proposed information collection. This critical period for feedback is open until November 16, 2026. Such comments are instrumental in assessing the impact of collection requirements, minimizing reporting burdens, and enhancing the overall quality, utility, and clarity of the information gathered.
The logistical details of the collection indicate an estimated 50,000 respondents from households, each expected to spend approximately 50 minutes. This translates to an estimated total annual burden of 41,667 hours, with no direct cost to the public beyond their time. Participation is voluntary, and the legal authority for this collection stems from Title 13, United States Code, Sections 141 and 182, and Title 29, United States Code, Sections 1-9. The Office of Management and Budget (OMB) control number for this collection is 0607-0354.
The Path Forward for National Statistics
The Census Bureau's concerted effort to modernize the ASEC through self-response options reflects a broader trend towards leveraging technological advancements in federal data collection. While the transition promises efficiencies and potentially broader reach, the rigorous field testing underscores the bureau's commitment to maintaining the high standards of accuracy and comparability essential for national statistics. The findings from this 2027 Field Test will be pivotal in shaping the future methodology of the ASEC, directly influencing the reliability of national estimates on poverty, income, and health insurance for years to come. The process emphasizes a careful, evidence-based approach to evolving critical data infrastructure, with opportunities for public input at key stages.
