Except the biggest drop was among teenage girls. Housing affordability and cost of living isn't usually yet a concern to most teenagers, and to the extent that it is a concern, it is equally a concern to teenage boys who haven't felt the same decline in happiness.

I suspect you're right, in general, but teenage girls may also be more susceptible to "future worry" than the boys are.

Tell the girls that housing will be unobtainable and they start worrying; tell the boys and they laugh. Not saying it's the case (and it's likely that the cause is more social than financial) but it could be.

Even if it is the biggest drop it is not the only drop.
