Data

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) and LEHD Origin-Destination Employment Statistics (LODES) data are available online for public use. Confidential microdata are available to qualified researchers with approved projects through restricted access use in Census Research Data Centers.

Quarterly Workforce Indicators (QWI)

The Quarterly Workforce Indicators (QWI) are a set of economic indicators including employment, job creation, earnings, and other measures of employment flows. The QWI are reported using detailed firm characteristics (geography, industry, age, size) and worker demographics information (sex, age, education, race, ethnicity). QWI data are available through the following access tools:

LODES Help

LEHD Origin-Destination Employment Statistics (LODES)

LEHD Origin-Destination Employment Statistics (LODES) used by OnTheMap are available for download below. Version 7 of LODES was enumerated by 2010 census blocks. Previous versions of LODES were enumerated with 2000 census blocks.

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 2002–2011.

To browse the LODES data files in their directory structure or to access them with FTP program (must be able to access HTTP), go to http://lehd.ces.census.gov/data/lodes/.

 

Job-to-Job Flows (J2J) (Beta)

Job-to-Job Flows (J2J) is a new set of statistics on worker reallocation in the United States constructed from the LEHD data. The initial release of national data distinguishes hires and separations associated with job change from hires from and separations to nonemployment. Future releases will be published at more detailed levels of aggregations, and will tabulate the origin and destination job characteristics of workers changing jobs.

Documentation and CSV files are available for download here: http://lehd.ces.census.gov/data/j2j_beta.html

To browse the J2J data files in their directory structure or to access them with FTP program (must be able to access HTTP), go to: http://lehd.ces.census.gov/data/j2j/

A web-based data visualization tool will be released in 2015.

Restricted-Use Microdata

In addition to the public-use Quarterly Workforce Indicators data and LODES data, LEHD microdata are available for research use in approved projects. Researchers interested in using restricted-use LEHD data must submit a proposal to conduct research at a secure Census Research Data Center (RDC). LEHD data available in the RDCs includes job-level quarterly earnings history data, person-level demographic data, establishment-level firm characteristics, and establishment-level Quarterly Workforce Indicators. Detailed information about restricted-use LEHD data, including available states and years, is on the CES LEHD Data page.
