Child-safety laws may reduce the birth rate
This is an actual conversation I had to have with my wife, having a third kid definitely requires a larger vehicle as the vast majority of cars today simply don't work for a family of five. Child car seats are too wide and the backseats of most cars are too narrow, and the price jump to a vehicle that would be able to handle three child car seats at once is enormous. Throw in some dogs, a couple pieces of luggage that any nuclear family would have to tote around, plus a stroller and it becomes prohibitively tight.It took me MONTHS of shopping and playing child-seat-jenga in various car dealership lots before I finally found a sedan that was actually able to hold everything (thank you, Volkswagen, for making an actual family sedan that could fit a family!).
