My own data point:

When I was little all my friends were in a radius of 10 minutes walking time.

When I grew up but I was still living with my parents that expanded to about one hour walking or public transport, or bicycle, or car for the very few friends I had outside my city.

That didn't change when I moved to my own place. Most of my friends were between 40 and 60 minutes away. The closest ones, within 5 minutes, were new friends I met in places further away.

I live outside a city now and my friends are between 40 to 80 minutes away, by car.

The number of people I meet is about the same, some are new friends some are old ones.
