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 "Four fifths of persons with an immigration background were themselves immigrants (first generation foreigners and native-born and naturalised Swiss citizens), whereas one fifth were born in Switzerland (second generation foreigners and native-born and naturalised Swiss citizens).". Is that enough to answer the question?
Answer: yes
