>This is a long term trend, and it has been on the trajectory to where we are now for a long while.

Economic conditions (real and imagined) in urban and suburban areas not unlike those seen in 1920 (automation resulted in massive economic gains capture) have caused total replacement fertility to drop in those areas to rates similar to 1920 (total TFR 2.3 at 50% rural -> likely urban TFR much lower).

This isn't so much as "long term trend" as it is "returning to the post-industrial baseline"; doomerism doesn't help, but their choice to not reproduce will improve the climate and resources available to my children so I find it rather difficult to see this as a problem.
