I'm pretty sure these are PPP measures.
-Thank you for your your answers, but maybe I didn´t formulate well the Third -question. Althought this data for Third world is PPP, the purchase power -of the dollar itself devaluates each year. So, when I compare poverty levels -from 1990 to 1998, for instance, I should have two adjustements: 1st-For PPP in both 1990 and 1998 data 2nd-A conversion for 1998 to 1990 to make up for the dollar devaluation (corresponding to USA inflation?). Is it done? I´m wrong about necessity of those corrections?
