There was the natural decline in birth rates due to economics and improved health care but the majority of countries are now trending below replacement, 2 births per woman.

The majority of countries are now inverting to a reverse population pyramid with aging populations that are difficult to sustain.

Globally the birth rate is now between 2.1 and 2.3, with several notable countries being caught off guard. China is trending towards 1 birth per woman and India dropped substantially to be below 2 for the first time. Both countries had planned to have expanding populations in their economic model forecasts until 2040+.

The west has a major issue as the modern monetary policy fallacy assumes a growing population to have expanding production potential that allows you to run endless govt deficits. Even record setting mass migration isn't working as a band-aid solution. Skilled migration is very effective, but unrestricted unskilled migration is just driving up costs faster than increases in productivity. Government planners seem to be stuck on 'It worked during the industrial revolution where people could work in factories' but we outsourced all those jobs.

The only countries that have maintained fertility are the African nations that did not get the safe and effective jab, much to the regret of Bill Gates and the WHO. The research studies so far show a temporary drop in fertility that recovers but they haven't really addressed why, and also what happens if you keep boosting. They also claim its a feature not a glitch that the mrna spikes hit the baby if you a preggo as well.

The birth rate is also lower than during the GFC.

Govts are going to have to start cutting back on spending sooner rather than later at this rate, unless AI massively boosts productivity and magically creates jobs.
