Longitudinal Employer-Household Dynamics (LEHD)

The Longitudinal Employer-Household Dynamics program is part of the Center for Economic Studies at the U.S. Census Bureau. The LEHD program produces new, cost effective, public-use information combining federal, state and Census Bureau data on employers and employees under the Local Employment Dynamics (LED) Partnership. Their mission is to provide new dynamic information on workers, employers, and jobs with state-of-the-art confidentiality protections and no additional data collection burden.

The Census’s Longitudinal Employer-Household Dynamics (LEHD) program contains several datasets, one of which is the Origin-Destination Employment Statistics (LODES) dataset. This dataset further contains three parts:

• Origin Destination
• Residence Area Characteristics
• Work Area Characteristics

These three pieces together provide information on commuting patterns by 2-digit industry between census tracts.

Emsi uses them together to form the basis of Occupation by Residence data. Emsi also uses Workplace Area Characteristics (WAC) to help build the commuting data used in Emsi’s Input-Output model.
