For example, I have data from a survey of adult citizens in 2014 showing an average annual salary of about 20000 LCU. I would like to find a comparable measure of the standard of living in Lebanon and other countries around the world, calculated from these surveys of annual income.
Using the private consumption PPP factor here https://data.worldbank.org/indicator/PA.NUS.PRVT.PP?view=map&year=2014
Lebanon's PPP conversion factor is 843.264.
So a Lebanese annual salary of 20000 LCU has the purchasing power in USD equal to
20000/843.264 = 23.71 USD.
How does this result make sense? And perhaps I should not be using PPP but a different exchange rate?
