This is how it was in the US too growing up in the 1970s and 1980s, everyone had a clothes line in their yard. But by the late 1980s it seemed everyone started getting clothes dryers.
Depends on where you lived. In rural areas, or in older city apartments, yes perhaps. My parents house was built in a subdivision in the 1960s and had an electric clothes dryer on day one.
Clotheslines were not the norm in the 1970s US in my experience. Dryers, like dishwashers, took longer to be broadly adopted than other major appliances but they were hardly uncommon in the 1970s or even earlier.
My mom still hangs clothes on clothesline. I used to hate it when she would hang towels on the line because they would get hard. I also grew up wearing cloth diapers. We grew up poor.
