As part of contract work for economist Raaj Sah, I reviewed the literature on some questions related to demographics. Specifically, I looked at causes for the decline in fertility in recent times to ultra-low levels.

A preliminary write-up of my findings is available here (PDF, double-spaced, 48 pages).

In the process of doing this research, I collected and synthesized a lot of demographic data. I started recording my findings at demography.subwiki.org.
