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 the same census, three departments bordering Paris, Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne, had population densities of over ten thousand people per square kilometre, ranking among the ten most densely populated areas of the EU.". Is that enough to answer the question?
Answer: no
