Layoff Tracker 2009
Mibazaar has created this Layoff Tracker to show the effect of the downturn on US jobs. The map shows layoffs for January 2009 at America's 500 largest public companies. That is 138,252 job losses in total in January alone from just 500 companies.
The companies are marked on the map based on the address of their headquarters, which may not necessarily be the location where the jobs have been cut. I think there is an opportunity here for someone to produce a Google Map mashup showing current unemployment rates in all the US states.
Despite the inexplicable decision not to use Google Maps :) I like this animated timeline map by MSNBC
