Terrorism and poverty

According to UPI:

Alberto Abadie of Harvard University's Kennedy School of Government said there is no significant relationship between a country's wealth and level of terrorism once other factors, like the country's level of political freedom, are taken into account.

The researchers reviewed the World Market Research Centre's Global Terrorism Index and found no clear correlation between terrorism and poverty.

Hmmm, I wonder if there is a correlation between terrorism and being raised in a Middle Eastern Muslim country.
