Investigating the Bureau of Labor Statistics: An In-depth Look
The Bureau of Labor Statistics (BLS), a key organization established in 1884 during President Grover Cleveland's administration, has been providing vital data that impacts the economy and society for over a century. The BLS is renowned for its role in providing data about the labor market and economy, including employment, unemployment rates, wages, and inflation.
The BLS is composed of various divisions and offices that collaborate for assembling, analyzing, and distributing these vital labor statistics. They employ various tools and techniques to guarantee the accuracy and dependability of their results, including phone surveys, web surveys, on-site visits, and secondary sources.
Despite criticisms about the methods used by the BLS, it remains a valuable source of data for policymakers, businesses, researchers, and individuals. This data is trusted by economists, businesses, the public, and academia for making informed decisions about employment trends and market conditions.
Shift in Data Collection Methods
Historically, BLS data collection involved extensive field surveys and direct data gathering from respondents to produce core statistics like employment and wages. However, over the years, the BLS has evolved its data collection methods. Today, the Bureau relies more on administrative records, supplemented data sources, and more selective surveying due to resource constraints.
For instance, the Quarterly Census of Employment and Wages (QCEW), a key BLS product, primarily uses administrative data from state unemployment insurance programs, supplemented by specific BLS surveys such as the Annual Refiling Survey and Multiple Worksite Report. This shift towards leveraging existing administrative records covers over 95% of U.S. jobs, reducing the need for solely direct employer reporting.
Resource Constraints and Modernizations
In recent years, partly due to staffing cuts and budget constraints, the BLS has reduced direct data collection efforts in certain areas. For example, during 2025, the BLS suspended Consumer Price Index (CPI) data collection entirely in some locales and reduced sample sizes elsewhere to align with resource availability. These suspensions reduced the number of collected prices and rents for CPI calculation but were statistically analyzed by BLS to have minimal effect on overall CPI accuracy at the national level.
In addition to these reductions, the BLS increasingly supplements traditional surveys with alternative data sources such as purchased data files, crowd-sourced data, and administrative records to maintain and expand data coverage despite workforce reductions. These changes were driven partly by federal funding cuts and job attrition of trained statisticians, which impacted BLS’s capacity for extensive field surveys and error adjustments.
Ongoing Modernizations
In April 2025, BLS also began implementing a redesigned Current Population Survey (CPS) sample based on 2020 Census data; however, the rollout involved some initial weighting and coding errors, reflecting challenges in adapting data collection methods and technology.
Despite these challenges, the BLS continues to strive for data integrity, using statistical techniques to minimize mistakes and providing transparency in their approaches. The BLS's Occupational Outlook Handbook, for example, offers detailed information about different jobs, including job prospects, training needs, median pay, and future growth. The Consumer Price Index (CPI), monitored by economists, tracks prices over time and helps figure out inflation and deflation rates.
In conclusion, the BLS data collection has shifted from intensive direct survey efforts towards greater use of administrative data and alternative data sources, with recent years marked by reductions in direct collection due to resource constraints and ongoing modernizations in sampling and weighting methodologies. Despite these changes, the BLS remains a crucial source of data for policymakers, businesses, researchers, and individuals to make informed decisions about employment trends and market conditions.
