I want to know the answer to the following question:
How many people lived per square kilometer in the city limits?
All the background I'm provided with is that "According to Eurostat, the EU statistical agency, in 2012 the Commune of Paris was the most densely populated city in the European Union, with 21,616 people per square kilometre within the city limits (the NUTS-3 statistical area), ahead of Inner London West, which had 10,374 people per square kilometre.". Is that enough to answer the question?
Answer: yes
