I'm sorry but IQ is technically not related to one's level of education but rather measures a person's potential to learn or at least being able to comprehend complex principals. I believe that for the topic being discussed and particularly with respect to the question as asked by
cranky108, we should really stick to original inquiry, does EDUCATION level play a role in the birthrate of a society. And I say yes, but only if you look at a large enough sample since there are always exceptions when dealing with individuals and even when looking at certain sections of society. Take for example America. Over the years, as both industrialization and public education has changed the face of the country, the actual birth rate has declined due to the effect of BOTH trends. In the case of moving from an agricultural based economy to when where most of the people were employed in manufacturing pursuits the need for large families was reduced. This was further impacted by raising levels of literacy and education particularly as it applied to girls and women attending school and getting an education, and this trend accelerated when more and more women started to attend colleges and delayed marriage as they pursued first a higher education and then the careers that they now were qualified for.
But even now there are exceptions to this due to cultural and in some cases even ethnic or religious norms. You can all remember when it used to joked about how Catholics always had big families and while that has NOT held true for me personally as I didn't come from a big family and neither did my parents and both sides of my family have been of Catholic stock for several generations, but there were some, like my two cousins with their combined 16 kids. And even today there parts of this country where those situations still apply at least antidotally. Take Utah for example or any local with a significant LDS population. You will find large families and one could hardly say that this was the result of a lack of education or even lower intelligence, since I work with many Mormons and I have yet to find any whom I would say have chosen to have large families out of ignorance or a lack of education.
Anyway, I think the original question, as asked, was absolutely an appropriate one since I believe that there are social factors at work which are related to education and educational opportunities, and the responses should have stuck to that topic.
