Really depends on the region
Generally speaking, high birth rates are/were common in poorer countries for family labour. More children = bigger workforce.
As time went on and humans industrialized, the need for "quantity over quality" slowly declined.
Wealthier regions have also seen a decline for other reasons; mainly pertaining to high costs of living and not wanting to bring children into the world if they will have a hard life. Most people raise their kids avoiding the hardships they grew up with themselves.
If raising a child costs a fortune and the choice is between living with wealth or having a child... Well tradition is dying out and I don't think most people still want kids for the sake of it or for family businesses
TLDR; we're just becoming more selfish as a civilization. Having children later, or not at all, so that we can live our best lives and not sacrifice for something you might not even want with all your heart
