I want to know the answer to the following question:
What percentage of the population aged 15 and over were shown to have an immigrant background as of 2012?
All the background I'm provided with is that "Additionally, the figures from 2012 show that 34.7% of the permanent resident population aged 15 or over in Switzerland, i.e. 2,335,000 persons, had an immigrant background.". Is that enough to answer the question?
