But when China instituted its one-child policy, there were countless cases of infanticide, forced abortions, and forced sterilizations, and Chinese couples didn't have to be stopped from pumping out 275 kids each. How can Zootopia avoid its fate? Well, it could institute strict population control. Hundreds of billions will be doomed to ugly deaths, while the survivors scrape out low-tech lives in the ruins of an arrogant metropolis.

If the Hopps family and everyone else in Zootopia keeps breeding like their biology drives them to, they'll strip the land of natural resources in mere decades. Walt Disney StudiosĪ staggering population boom combined with out-of-control resource consumption produces a clear end result. Judy's mom simply couldn't have pumped out 275 kids if each one took nine months, and we see Fru Fru, a shrew, go from her wedding night to heavily pregnant in a matter of days. Especially since, while the animals have developed human lifespans, they've kept their original pregnancy cycles.

With no predators to eat some of them, it won't take long for Zootopia's population to careen out of control, even if most animals show relative restraint. Even if these are career deer and mice who keep their reproduction rate down relative to the boonies, a single litter of, say, lemmings, produces an average of seven babies. Zootopia has lots of predators, who reproduce conservatively, but we also see scores of prey, who mate at a pretty healthy clip - lemmings, mice, shrew, deer. Are they all reproducing at their respective species' natural rates? It seems like they're instinctively driven to, if Judy's parents are any indication. Well, NYC has 42.6 times the population of Yonkers, so Zootopia's population is implicitly just shy of 3.5 billion - 3,469,165,080, to be exact. Zootopia's co-director called it the Yonkers to Zootopia's New York City. Judy's hometown of Bunnyburrow, despite being 81 million strong, is considered a backwater Podunk.
