Longitudinal Employment and Household Dynamics (LEHD)

PDF files can be viewed with the Acrobat® Reader®

The Longitudinal Employment and Household Dynamics (LEHD) program is conducted by the U.S. Census Bureau. LEHD is potentially an alternate/additional source of place of work and flow data. LEHD links State Quarterly Census of Employment and Wages (QCEW) with federal administrative records. Data covers 90% of the total US workforce. Since Spring of 2012, the LEHD program has started including federal - employment (excluding military jobs) and self - employment data. The civilian federal employees are tracked by the U.S. Office of Personnel's Management data files. The self-employed jobs are identified by using tax data. To get more updates on LEHD research, please visit We encourage the transportation community to evaluate these data at small geography and identify problem areas and approaches to improve data quality.

LEHD program makes several data products that can be used to understand the workforce dynamics of specific groups. The data includes both publicly available data and restricted-use micro data. Quarterly Workforce Indicator (QWI) and LEHD Origin-Destination Employment Statistics (LODES) are publicly available. Caution! USDOT recommends that this data be carefully reviewed before use in any transportation application.

The following reporting and mapping tools are available that were developed based on the public-use data.
