1 Ric Olie: Coruscant. The entire planet is one big city.
1 Anakin: Wow! Let's see: population density of 50,000 per square kilometre...
2 Anakin: That's 10¹⁴ people and no arable land. You'd need to import the entire output of 10,000 agricultural planets to feed them.
3 Anakin: At a cargo capacity of 2,500,000 metric tons each, you need 80,000 Super Star Destroyers delivering fresh produce every day.
4 Ric Olie: Anakin, has anyone ever told you you're just an annoying little kid?
4 Jar Jar: Meesa agree...

Yes, that cargo capacity is a canonical figure, after correction for misprinted data that made the cargo capacity ten times less (and would have subsequently required Coruscant to use ten times as many ships to deliver food).

Do not think about what they do with all the sewage.
