The DEEP-MAPS Project uses current statistical tools to provide estimates of the impact of the current employment crisis on places and people. The model was developed by Yair Ghitza, Ph.D., and Chief Scientist at the national data company Catalist. A working paper, open code, modeled census tract level estimates, and this website have been created through work done together with Mark Steitz. These estimates will be updated monthly as new official unemployment figures are released.
