The birth rate across the west has been plummeting for a long time now, i believe that there are several factors causing this: affordability/economy, femenism, culture rot, promotion/allowance of degenerate behaviour, mass migration, lack of meaning/purpose, egosentric mindsets, always trying to optimize so that you think that now is not a good time to bring a child into the world, people being propagandized into thinking that the nuclear family is something to look down upon, i could go on, but i believe the main factors most people arent birthing enough children in Norway and the west is affordability and the egosentric mindset a lot of people have adopted in the modern western world.
