To commemorate the 25^th anniversary of the Wilson Center’s Environmental Change and Security Program, I have a prediction: by ECSP’s 50^th anniversary, the idea that one could discuss national and international security without examining the situation, status, and security of women will be seen as laughably naïve. Over the next twenty-five years, I predict that every “Intro to International Relations” and “Intro to National Security” class (and every QDR and QDDR) will begin by examining the critical linkage between what is going on with women and what is going on with nation-states.

For the past two decades, scholars and policymakers have examined the phenomenon of China’s missing females and corresponding numbers of involuntary bachelors to better understand the causes and consequences of the state’s demographic plight. China has both a heavily skewed male to female sex ratio and faces a drastically shrinking population in coming years.

The emerging subfield of “security demographics” is interested in how demographic trends, such as youth bulges, high or low fertility rates, and sex ratios affect the security and stability of nation-states and regions. In our research, Andrea Den Boer and I have attempted to show that abnormally high sex ratios – situations where there are significantly more men than women – have been a security concern in the past and may affect security and stability in the future.
