I'm of an age to have grown up like that, and one of the real drags was having to take my 3-5 year-old sibling along on whatever activity the rest of us were up to. ("But mom, we're building a fort - do I have to?") The other kids with younger siblings did the same. As I recall, at five I wasn't to leave the yard by myself, but as a mixed-age group of ~3-11 year-olds, yeah: we ran around all over the place together. The older kids took on responsibility for the younger ones.

So, yeah, that's eighties suburbia, and my sister wasn't less than two. On the other hand, if there'd been a larger age difference (and, maybe if I'd been a girl? My mum was more progressive about gender roles than most of her contemporaries, but still) I expect she'd have been entrusted to me earlier. Starting at the age of ~4 I'd been left alone with my sister for up to an hour while she napped, with the instruction to run next door to get my mother if she woke up.

By the way, I think all of that was fine.

It was not like that in the London suburb I grew up in in the 80s. I think it was more common in smaller and poorer towns - maybe because people had less space at home. I agree the age gap probably affects it a lot. Keeping an eye on a younger child at home with help near by is very different from going out.

Kids spending a lot of time in front of the TV was already a concern in the 80s so screen time was definitely a problem back then. IIRC the average amount of time children spent watching TV a day was about five hours a day in the UK.

Of course. Regions and cultures and families varied all over the place - and still do today. I wasn't trying to make any kind of universal claim, just explaining how our social group handled the "but what do you do about younger kids?" question the GP asked.

Yah. Screen time (and, once I got older, specifically video games) caused a lot of parental angst amongst my peer-group's parents, too. My family didn't have a TV, so I read lots of books. Funnily enough, I (later) ran across Victorian-era think-pieces about how books were damaging to young people for all of the same reasons that people are (now, and back when we were kids) concerned about screens.

By the way, this same subject came up in another thread a few days ago, and I had this to say:
