I am a retired US statistician. I have done research on housing, education, environment & development issues, nutrition, employment & income, and I briefly consulted for the UN Development Program and the US Congress' Office of Technology Assessment.
I have contributed a little to Wikipedia, when I see a gap in a subject which I know something about. I use it often, and want to learn how to contribute more.
