Longitudinal surveys repeatedly query the same individual, household, or business establishment over time.  They provide essential insights into how the labor market functions, offering a different perspective from more traditional surveys. 

Longitudinal data systems offer the ability to perform data matching on participants to track their education and labor market outcomes over time.

The Power of Longitudinal Data

In the directory on this page, ETA has assembled information on all the major longitudinal surveys that include information on workers.

The Statewide Longitudinal Data Systems Grant Program 

The National Center for Education Statistics (NCES), under the Institute of Education Sciences (IES) at the U.S. Department of Education, funded the design, development, and implementation of a Statewide Longitudinal Data Systems (SLDS) dashboard to efficiently and accurately manage, analyze, disaggregate, and use individual student data.

The data tracked have the capacity to link individual student data across time and across databases.  This includes data that matched teachers to students, promoted the linking of data collected or held by various institutions, agencies, and states, and protected student privacy consistent with privacy protection laws.

The Workforce Data Quality Initiative

The Workforce Data Quality Initiative (WDQI) at the U.S. Department of Labor (DOL) complements the Statewide Longitudinal Data Systems (SLDS) grant initiative that was implemented through the U.S. Department of Education. 

WDQI grants to state workforce agencies (SWAs) supports the development of, or enhancements to, state longitudinal administrative databases to better integrate workforce and education data.  These funds help states incorporate workforce information into their longitudinal data systems to allow following individuals through school and through their work life. 

                            

Other Longitudinal Surveys

The Bureau of Labor Statistics (BLS) National Longitudinal Surveys (NLS) are designed to gather information at multiple points in time on the labor market activities and other significant life events of several groups of men and women.

The Census Bureau Longitudinal Employer-Household Dynamics (LEHD) program creates statistics on employment, earnings, and job flows at detailed levels of geography and industry and for different demographic groups.
