I lived and worked in Bangladesh for six months in 2003. I was the Project Manager for the "National Private Sector Survey of Enterprises in Bangladesh" - a GEMINI-type survey of over 12,000 businesses across the country. I lived in Dhaka (the capital) for six months and traveled to several other urban and rural areas.

Photos from the survey.

A few interesting statistics about Bangladesh:
Over 135 million people; about the same area as Greece or Alabama or Arkansas.
Approximately 1/3 of the country is flooded annually.
