New York City boasts a population of approximately 8.8 million people, while Paris has about 2.2 million residents. This means NYC is roughly four times larger in terms of population.
When it comes to physical size, New York City covers 302.6 square miles, compared to Paris's 41 square miles. The Big Apple is therefore about seven times larger in land area.
Despite its larger overall size, New York City has a lower population density—around 29,000 people per square mile—while Paris packs about 54,000 people per square mile, making the French capital nearly twice as dense.
In summary, New York City surpasses Paris in both total population and land area, but Paris is significantly more densely populated.
