I want to know the answer to the following question:
How much did Valencia's foreign population rise from 2007 to 2008?
All the background I'm provided with is that "The third largest city in Spain and the 24th most populous municipality in the European Union, Valencia has a population of 809,267 within its administrative limits on a land area of 134.6 km2 (52 sq mi).". Is that enough to answer the question?
