LEHD makes available several data products that may be used to research and characterize workforce dynamics for specific groups. These data products include online applications, public-use data, and restricted-use microdata. The Quarterly Workforce Indicators (QWI), LEHD Origin-Destination Employment Statistics (LODES), Job-to-Job Flows (J2J), and Post-Secondary Employment Outcomes (PSEO) are available online for public use. Confidential microdata are available to qualified researchers with approved projects through restricted access use in Federal Statistical Research Data Centers (FSRDCs).
Note: The data released by LEHD are based on tabulated and modeled administrative data, which are subject to error. Because the estimates are not derived from a probability-based sample, no sampling error measures are applicable. However, the data are subject to nonsampling errors, which can be attributed to many sources: misreported data, late reporters whose records are missing and imputed, and geographic/industry edits and imputations. The accuracy of the data is impacted by the joint effects of these nonsampling errors. While no direct measurement of these joint effects has been obtained, precautionary steps are taken in all phases of collection and processing to minimize the impact of nonsampling errors.

Job-to-Job Flows (J2J)Job-to-Job Flows (J2J) is a set of statistics on job mobility in the United States. J2J include statistics on: (1) the job-to-job transition rate, (2) hires and separations to and from employment, (3) earnings changes due to job change, and (4) characteristics of origin and destination jobs for job-to-job transitions. These statistics are available at the national, state, and metropolitan area levels and by worker and firm characteristics.
To browse the J2J data files in their directory structure or to access them with a FTP program (must be able to access HTTP), go to: lehd.ces.census.gov/data/j2j/. J2J data can also be accessed via Job-to-Job Flows Explorer. This analysis and visualization tool allows for the construction of tables, maps, and charts to compare, aggregate and analyze flows by worker and firm characteristics.

LEHD Origin-Destination Employment Statistics (LODES)
LEHD Origin-Destination Employment Statistics (LODES) used by OnTheMap are available for download below. Version 8 of LODES was enumerated by 2020 census blocks. Previous versions of LODES were enumerated with 2010 census blocks (LODES7) or 2000 census blocks (LODES5).
Data files are state-based and organized into three types: Origin-Destination (OD), Residence Area Characteristics (RAC), and Workplace Area Characteristics (WAC), all at census block geographic detail. Data is available for most states for the years (2002-2021).
To browse the LODES data files in their directory structure or to access them with a FTP program (must be able to access HTTP), go to lehd.ces.census.gov/data/lodes/.
