I'm planning a trip to Paris this year and plan to see lots of tourist attractions, including the Arc de Triomphe, Eiffel Tower 
That sounds like a lot of fun, Paris is probably a really fascinating place. Do you know how many people live there roughly?
In 2016 the population of Paris was around 12,142,802, which accounted for approximately 18 percent of the population of France
Wow that's a lot of people, do you know what some other big cities in France are?
Besides Paris, which is the capital and most populous city in France, there is Lyon and Nice
