It's that time of year again.

Eager kids are about to grab their backpacks and head to the closest bus stop. But while the closest bus stop for older kids is most likely in the suburbs, city streets remain childless for the most part—unless you count the small population of toddlers in strollers. Among adults who live with children, almost two thirds, 63%, said a neighborhood’s school district is one of the most important considerations when finding a home. Per Trulia:

As we showed last year, the most “attractive” school districts – those with the highest backpack-to-stroller ratio – are smaller, suburban districts, while big-city school districts have more strollers than backpacks. But even within big cities, there’s huge variation: New York, Los Angeles, Chicago and other cities all have extreme “stroller” neighborhoods, where the preschoolers far outnumber the elementary-school-age kids, but also a few “backpack” neighborhoods, which have more elementary school-age kids than preschoolers.
