covid, expensive housing, war, climate change, death, destruction, doom
Honestly, I doubt any of these apart from expensive housing is playing a significant role. I haven’t seen any reliable data on it, but I suspect a vanishingly small number of people genuinely choose not to have kids “because I don’t want to bring kids into this terrible world”. The cost of living thing though? That’s something that affects the parents and their ability to feel like they even can raise a child right now.
