2. Is Utah just like that because of the Mormons?

3. having kids is rewarding, but damn its expensive

4. Sounds like a combination of people living longer and everything being more expensive for larger families to be less desirable.

5. The color coding is pretty misleading here, ngl

6. Too many mega billionaires preventing money from doing as much as it could be doing. Not enough left for young people to feel like they can start families.

7. I feel like these colors should be swapped, with the darker colors being higher population of under 18. Not surprised by the results on this one, higher cost of living/less religion = less kids.

8. I think it’s almost always more intuitive to have lighter, less saturated colors depict smaller numbers. Or warmer colors for higher and cooler colors for lower.

9. An aging population into a monetary system that requires a growing population. What could possibly go wrong?

10. 3% is the difference between bright red and deep purple. ok

11. Utah now has below replacement fertility rates. Still above average for USA, but the notion of a bunch of 8 person families running around is at least 25 years out of date.

12. Daycare and camp is prohibitively expensive. College will be even more. I would love more children but having them has almost become a luxury and I can’t afford more

13. In my opinion this is the real reason roe v wade was overturned. Forced births.

14. Lord of wealthy countries are under the threshold of repopulation. South Korea for instance… https://youtu.be/Ufmu1WD2TSk?si=wg9huaRjc9f4I4Sl

15. Here’s a version with somewhat improved color scheme, although Utah still throws the scale off:

16. Gee it’s almost like they made it too expensive to have lots of kids or something.

17. Here’s a version of the time series chart that better shows the slope by starting all Y axes at 15%, and also uses a color scheme which might be better:

    Font also changed because I’m on a different machine.

18. This is why housing prices are completely insane here in Utah

19. It’s why immigrants are so important. Without them the economy would collapse, but xenophobia rules the country now.

20. Them Mormans…they like to make some babies.

21. Mormons single-handedly keeping the American population from plummeting
