I want to know the answer to the following question:
What percentage of the immigrants were born in Switzerland 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?
Answer: no
