A 4-year-old on reality TV is being followed by a camera crew, and is therefore by definition not alone.
That being said, it is common in urban areas (at least in LA) to see relatively young children commuting or running errands by themselves. But I never see that when I go back to surburbia. It's not an issue of neighborhood safety; the suburban areas are far safer. It's a parental risk tolerance issue.
