I want to know the answer to the following question:
A 2005 survey indicated that how many communities comprised of non-indigenous people existed in London?
All the background I'm provided with is that "In January 2005, a survey of London's ethnic and religious diversity claimed that there were more than 300 languages spoken in London and more than 50 non-indigenous communities with a population of more than 10,000.". Is that enough to answer the question?
Answer: yes
