This is just purely anecdotal from my circle and what I’ve observed, and I have NO data to support this…but it seems like:
1. People are having much smaller families than when I was growing up in the 70’s and 80’s (1-2 kids is the norm now vs. 3-5 kids then…my parents had 6 kids born in the 1960’s and 1970’s)
2. College educated higher income people especially seem to be either having no kids at all, or having them much later in life than the past
3. I am not as sure of trends in terms of family size and age having children within the lower income, lower educational levels (I would assume it to be larger families and having children at earlier ages)
