For everyone that has three kids, you know how hard it can be to put those three kids in a car with approved child safety car seats. It can be a challenge in many models of vehicles. But now work by Jordan Nickerson and David Solomon, professors of finance at the Massachusetts Institute of Technology and Boston College has linked the declining birth rate of American women on the design and carrying capacity of American vehicles.
In fifty years the birth rate of American women has fallen from 2.12 children on average to 1.73. Of course the fact that there’s available birth control and better educational and work opportunities have impacted these statistics. But these researchers point out that declining birth rate curves do not dovetail with just those factors.
The Economist Science and Technology page describes the researchers’ study, “Car Seats as Contraception”.

The researchers looked at the impact of car seat policies on American birth rates for 43 years to 2017. In 1973 only small infants had to be legally in baby car seats. Legislation then evolved to make it mandatory for children to be in car seats until they are eight years old.
So could that be the reason that there are fewer three child families?Read more »
