Talking about labor shortage, here is an interesting DER SPIEGEL article about skilled labor shortage in Eastern Germany (via Demography Matters).
I would also like to share this: The Chronicle of Higher Education created a very interesting interactive map on the the percentage of adults with college degrees over time in the USA. Check the map here. (Hat tip: Flowing Data)
1970 - % of adults with college degrees over time in the USA
2005-9 - % of adults with college degrees over time in the USA
