Partner with Us

The LEHD Infrastructure Files provide a detailed and comprehensive picture of workers, employers, and their interaction in the U.S. economy. This innovative data set is possible due to our partnership with the state Labor Market Information (LMI) agencies. This partnership has led to quality local labor market information that helps support decision making by Federal, State, local authorities, business, and organizations in areas such as:

  • Workforce development
  • Transportation planning
  • Emergency preparedness and recovery

The LEHD program continues to investigate means to improve the depth and quality of this data set as well as promote its use. If you are interested to working with us to further the goals of this program, please contact us.
