OnTheMap for Emergency Management Data Tool


OnTheMap for Emergency Management is a public data tool, developed by the U.S. Census Bureau, which provides an intuitive web-based interface for viewing the potential effects of disasters on the U.S. workforce and population.


Users can easily retrieve reports containing detailed workforce, population, and housing characteristics for hurricanes, floods, wildfires, winter storms, and federal disaster declaration areas.  The tool applies Longitudinal Employer-Household Dynamics (LEHD) data for planning and natural disaster management purposes.


LODES - LEHD Origin-Destination Employment Statistics - is used in the OnTheMap tool.  You can find more information on LODES in this LED training.

Webinar on Hurricane Preparedness Using OnTheMap


The U.S. Census Bureau and the Local Employment Dynamics (LED) Partnership in collaboration with the Council for Community and Economic Research (C2ER) host regular webinars to demonstrate the useful functions of the OnTheMap for Emergency Management data tool.


For example, the June 27, 2018 webinar, "Hurricane Preparedness with OnTheMap for Emergency Management," demonstrated how to use Census data to assess the possible impact of a potential hurricane.


Please see the links below to the recording for this webinar and another presentation available for your convenience.   

Other C2ER and the LMI Institute LED training offerings are at upcoming webinar events.


Recordings of past webinars and future webinars planned are also located on the Census website.

LEHD Interactive Mapping


This web-based mapping and reporting application is used to illustrate where workers are employed and where they live. The application is paired with reports on age, earnings, industry distributions, race, ethnicity, educational attainment, and gender, while the tool itself features comprehensive block-level coverage for home and work areas, six powerful analysis tools, user-created outputs, and easy-to-use online documentation.


OnTheMap for Emergency Management, an offshoot of this application, provides an intuitive interface for accessing U.S. population and workforce statistics, in real time, for areas affected by natural disasters
