Low birth rate and young people's sexual rights
Total fertility rate (the average number of children birthed by a woman) is estimated to be at around the global replacement rate of 2.0-2.4 in the 2020s. Where fertility rate falls below replacement rate, global population starts to go into decline, negatively impacting economic performance and increasing the relative number of elderly and infirm people in developed societies.
It has been suggested that one way of increasing birth/fertility rate is to relax laws against statutory rape and allow some degree of Youth-Adult Marriage, reintroducing pre- and postwar dating norms and normalizing teen pregnancies. More permissive norms with respect to the agency and capacities of youth might also be pursued to combat ageism, providing the basis for a broad cultural coalition between those concerned with the slow decline of western societies, and those more alarmed by potential back-slippage towards regressive social values.
