Boy can I appreciate this study. Upcoming grandchild #3 is causing a scramble for a mini-van to accomodate the growing family. The study claims to show that car-seat issues actually depress families’ having third children. Fortunately our own family can absorb the shock, but for others apparently it makes a real difference.
We estimate that these laws prevented only 57 car crash fatalities of children nationwide in 2017. Simultaneously, they led to a permanent reduction of approximately 8,000 births in the same year, and 145,000 fewer births since 1980, with 90% of this decline being since 2000.
Note: Yes, I’m in favor of car seats. As with lockdowns etc., though, it’s worth gaming out all the consequences.
