Technical notes

The HDI for 1994 is calculated on a different basis from that in previous years. Maximum and minimum values have been fixed for the four basic variables-life expectancy (85.0 and 25.0 years), adult literacy (100% and bOlo), mean years of schooling (15 and 0 years) and income (PPP$40,000 and $200). For income, the threshold value is taken to be the global average real GDP per capita of PPP$5,l20. Mulriplcs of incomc bcyond thc threshold are discounted using a progressively higher rate.
