Many of those amenities are not as relevant when you're older. Easy access to bars, restaurants, and clubs is not as important as a larger home and good school districts when you're a parent, for example. Access to things like healthcare, grocery stores, and target are not any more difficult and often easier to access in suburbs.

Basically, people's priorities change and the optimal living situation changes accordingly. On average, that is, I'm sure some people prefer city life into later adulthood, and some young people like suburbs.

"good school districts"

This point seems to be mostly American and a result of how schools get financed in the US and not inherent to cities. Schools being financed by very small areas they are located in is exacerbating the divide between poor and wealthy neighborhoods for no real reason. In contrast, when I grew up in Germany, kids had to commute from the suburbs and villages to the city to attend a really good school.

Parent engagement has a huge impact on how good a school district is. It isn't the funding. Poorly performing schools often get more funding.
