The negative correlation between fertility and intelligence (as measured by IQ) has been argued to have existed in many parts of the world. He found negative correlations between the intelligence of American adults and the number of children and siblings that they had, but only for females. He also reported that there was virtually no correlation between women's intelligence and the number of children they considered ideal. Declining diversity of wild-caught species puts dietary nutrient supplies at risk.

Effectively addressing the public policy challenges posed by population ageing will require an integrated portfolio of complementary initiatives. During Japans recent flu outbreak earlier this year, which reached record levels (Japan Times2018), a more widely accessible and efficacious flu vaccine would have helped not just to reduce the number of pneumonia cases among older adults (and likely mortality rates as well), but also to prevent hospitalization and other treatment costs, missed paid and unpaid work, and anxieties surrounding the prospect of becoming infected.

[1], Some of the first studies into the subject were carried out on individuals living before the advent of IQ testing, in the late 19th century, by looking at the fertility of men listed in Who's Who, these individuals being presumably of high intelligence. Falling birth rates eventually will lead to significant shifts in the age structure of Muslim populations. The findings from these investigations were consistent enough for Osborn and Bajema, writing as late as 1972, to conclude that fertility patterns were eugenic, and that "the reproductive trend toward an increase in the frequency of genes associated with higher IQ will probably continue in the foreseeable future in the United States and will be found also in other industrial welfare-state democracies.
