Cost of living in Cambodia

A friend shared this URL with me. http://darrenconquest.blogspot.com/2005/05/cost-of-living-in-cambodia.html

I wonder how much the price of things has changed since May 2005?

I read somewhere that the inflation rate is about 15% pa. Could somebody please enlighten me as to whether this is applies to the price of food, of housing, of something else - or if this is applies across the board?

Blessings.
