> There's little evidence to support the theory that at some point in the future, little girls will all suddenly decide to buck the trend set by their mothers, grandmothers, great-grandmothers, and all the adult women they see around them in the world, and have 2.1 children themselves.
There is some speculation - and some data which may or may not support it - that fertility may follow a "J" curve where it declines sharply with increased development and then slowly rises again above a certain level.
There is also some data to suggest that within a population, if a subset sees an increase in wealth, it can predict an increase in fertility within that subset.
Combined, a suggestion that does not seem unreasonable is that we develop certain expectations based on societal expectations, and as they increase it becomes harder and harder to justify additional children, but when people find themselves able to meet those expectations, the number of children goes up.
If that holds, then that would suggest the rate can be brought back up with sufficient societal assistance, which may or may not come as fertility rates becomes enough of a political issue. Whether that will actually work remains to be seen - we've already of course seen some pretty significant attempts, such as the escalating Hungarian family support scheme (total support for 3+ children amounts to over 300k Euro, of which about 1/3 is a non-refundable grant and the rest subsidized house loans), so we should start to get an idea of what a realistic cost to drive the rates back up will be, if it is viable, over the coming couple of decades as more countries experiment.
