Cost of living

I came to realise that many Cambodians earn something in the order of $100 - $500 /month as salary.

My family and I live in Toul Kork, which is noted on the map as the cheapest area to live in Phnom Penh.  (I think this is because it is not in the area of the riverside, the commercial areas or the area where many public offices are located.)  I see that it costs something between $250 - $700 /month to lease accomodation in this area.  There are more places available that are in the order of $400 - $500 /month than there are those in the order of those between $250 and $350.  Landlords want $650 or higher for the newer apartments, I am sure the bigger houses would be even more expensive.

Ie. I wonder how the Cambodians afford to live in their capital city?  The cost of accomodation is almost higher than what people earn, and people need to add the cost of food, electricity, transport, etc. to their living costs.  Ie. accomodation costs is not all there is to living.

I see that many people live with their extended families.  This is one way to reduce the cost.  I am sure, though, there are families who are unable to do this.
