In my last position before retirement I was Chief of the Population Estimates and Projections Section at the Population Division of the United Nations Department of Economic and Social Affairs (DESA) from 2006 to 2013. For details, please see the official website of the United Nations Population Division at: http://esa.un.org/unpd/wpp/
As you probably can guess I am a do-everything-myself fanatic. I like to do research, write content, design charts and interfaces, and code and implement websites or software. If I could, I would make the paper or construct the PC on which I work. Probably I am a fossil from a long-gone period befor the division of labor became the norm.
