Does the modern girl not ever leave their house, literally?

I lived by many girls around my age range (19-24) & from what I've seen most of them rarely ever left their front porch or even go around the block or corner of the neighborhood

I know this because back then I left the house everyday for school & attended to my morning chores around my grandmothers house & went jogging around the block almost constantly

& Not once did I ever see others my age or girls for the matter even leave their house

Is it a safety issue? Fear of getting approached?

Laziness? Rather be on their phones instead?
