The important think to remember is that a huge part of humanity lives on less than 2 dollars a day.
Wealth among the poorest has increased over the last 20 years but that does not matter. I think now about 1 billion people live on 2 dollars a day - It used to be 3 billion when I was younger.
If you go down the list above you will start to have to trade security for cheapness. However having a laptop does not make someone rich anymore these days.
Somalia for example, my friend who has been there has told me that fibre seems to be everywhere !
However You do not have to go to Somalia, you can choose a country based on factors that is important to you.
I doubt the veracity of this list. As an example, a flat in Belgrade, Serbia would run you 400 euros a month if you're lucky. That's almost 14 eur/day. Food alone can be over the $12 daily limit.
I'd caution anyone from taking this list seriously because it is based on reported income alone. There is a combination of credit purchasing and unreported income (cash exchange), each of which means cost of living is higher.
According to this [0] cost of living is $400+ without rent, which is a bit steep but much closer to the actual cost.
Can you give an example of such a place, where the total cost of rent, food and utilities (water, electricity) amounts to less than 50 USD per month?
