If we lived in a rural area. We would have half dozen kids. We even fantasies about it with my SO. But my SO has no interest in living in a rural area, so that is that.
They are more religious, but that is not the same as uneducated.
The education gap between rural and urban settings is a subject of much concern and unfortunately the tendency towards religious views has led to increased ignorance about sex as comprehensive sex ed is more likely to be rejected in rural areas replaced by "abstinence only" programs which result in higher rates of unplanned/teen pregnancy and even where comprehensive sex ed is offered, religious parents are much more likely to forbid their children from attending.
the belief that university knowledge generates economic wealth stems more from superstition than empiricism. Empirical investigation shows no evidence that raising the general level of education raises a country's income level.
But we know the opposite is true, that wealth leads to the rise of education - that's not an optical illusion"
