  1. Select the subset of the data you want (e.g. US academic) and download the XML file.
  2. Fix some validation errors: take out the “<” and “>” within the text of nodes (I use TextMate for this).
  3. Parse the XML file with a custom PHP script that creates a csv file with school, position, location and url to posting. Here is my simple script for the academic XML file.
  4. Save the csv file produced by the script in step 3 as an Excel spreadsheet (Google Docs doesn’t like csv’s).  Add a “Latitude” and “Longitude” column to the spreadsheet.
  5. Upload the Excel file to Google docs.
  6. Follow these directions to populate the latitude and longitude of each position+location.
  7. Publish the Google spreadsheet and save the unique id in the url that Google gives you.
  8. Sign up for a Google Maps API account.
  9. Follow these directions to produce a Google map of your postings.

UPDATE: This service may make this process a bit easier, produce cleaner maps and allow the incorporation of more information.

Maybe the AEA can follow these directions to produce these maps after this year.  Contact me with any suggestions or questions.

The demand-side is slightly tricky to interpret because it is a function of not only real employment demand, but the popularity of Indeed as a search platform. Here are some interesting facts:

Finance: Supply of jobs falls, demand increases

Financial Services and Banking job postings have decreased 39% since March 2008.

Clicks on Financial Services and Banking jobs have increased 96% since March 2008.

Construction employment falls

Healthcare bucks the trends

Tax-related employment is volatile

SimplyHired.com also has a trends section with similar patterns.
