I think that at least 6 months ago, the Wall St Journal published stats.
74% owned a washer
two thirds owned at least one car
one third owned a second car
I don't recall the rest. I do recall Ceci Connelly harping on how bad the economy was. That's hard to listen to especially when it was Moynihan who was pilloried when he found that welfare programs backfire.
In USA the car is a necessity (with the exception of inner cities where you can go around on a bus, this one third without a car probably lives there).
Two cars might mean, that one is still running and other is being fixed.
In older times poor people could have a horse or two and a wagon.
