{{Cquote|We find that increased education is strongly associated with delayed childbearing in both sexes and is also moderately associated with decreased completed or near-completed fertility. Women in the general population with higher adult income have fewer children, but this relationship does not hold within all educational groups, including our sample with elite educations. Higher-income men, however, do not have fewer children in the general population and in fact have lower childlessness rates. Further, higher income in men is positively associated with fertility among our sample with elite educations as well as within the general population among those with college educations. Such findings undermine simple statements on the relationship between status and fertility.<ref>''Human Nature'', [https://pubmed.ncbi.nlm.nih.gov/26181608/ Do high-status people really have fewer children? : Education, income, and fertility in the contemporary U.S], 2006 Dec;17(4):377-92. doi: 10.1007/s12110-006-1001-3.</ref>}}

The journal ''Intelligence'' published a journal article entitled ''IQ and fertility: A cross-national study'' and its abstract states: "Many studies have found a small to moderate negative correlation between IQ and fertility rates. However, these studies have been limited to the United States and some European countries. The present study was a between-nation study using national IQ scores and national fertility rates. There were strong negative correlations found between national IQ and three national indicators of fertility."<ref>[https://www.sciencedirect.com/science/article/abs/pii/S0160289607000244#:~:text=Numerous%20studies%20have%20confirmed%20that,with%20higher%20levels%20of%20IQ.
