- 62: Tunisia (cheapest)
- 100: Czech Republic
- 288: Cayman Islands (most expensive)
To calculate each country's Price Index value, we start by assigning a value of 100 to a
central reference country (that happens to be the Czech Republic).
Once the reference point has been established, the Price Index value of every other country in the
database is calculated by comparing their cost of living to the cost of living in the Czech Republic.
Therefore, if a country has a Price Index of 134, that means that living there is 34% more expensive than living in the Czech Republic.
