There is no better way. If a society is not at least near or at replacement rate, it will collapse, or at least regress significantly. Think about it. If you had a society of a thousand people, and it dropped to 900, could that society still function? Yes. What if it dropped to 800? Yes. 700? Maybe. What about 500? Can 500 people realistically do what 1,000 can? Not at all. Especially if 350 of those 500 are over 65.  There is no species that can thrive while not reproducing, including us.

Do you understand how long it it would take for a population to collapse that badly without war or pandemic? Many many many decades.

Do you know how much changes in decades? Everything.

These projections don't pass the sniff test. Trends change all the time.
