THE FUTURE BELONGS TO THOSE WHO SHOW UP: South Korea spent $200 billion, but it can’t pay people enough to have a baby.

South Korea recently broke its own record for the world’s lowest fertility rate. Figures released in November showed the average number of children a South Korean woman will have in her lifetime is down to just 0.79.

That is far below the 2.1 needed to maintain a stable population and low even compared to other developed countries where the rate is falling, such as the United States (1.6) and Japan – which at 1.3 reported its own lowest rate on record.

And it spells trouble for a country with an aging population that faces a looming shortage of workers to support its pension system.

You can’t subsidize kids enough to make them financially worthwhile, especially when the culture points the other way.

Also: car seats as contraception: “Since 1977, U.S. states have passed laws steadily raising the age for which a child must ride in a car safety seat. These laws significantly raise the cost of having a third child, as many regular-sized cars cannot fit three child seats in the back. Using census data and state-year variation in laws, we estimate that when women have two children of ages requiring mandated car seats, they have a lower annual probability of giving birth by 0.73 percentage points. Consistent with a causal channel, this effect is limited to third child births, is concentrated in households with access to a car, and is larger when a male is present (when both front seats are likely to be occupied). 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.”
