The map shows those territories where the human development index has increased from 1975 to 2002. Such an increase has occurred in the majority of territories.
The size of the territory shows where the most improvement has occurred. The biggest improvement to people’s lives has been in China and India because each fractional improvement is theoretically experienced more than 2.3 billion times in the combined populations of these territories.
Southeastern Africa, North America, Western Europe and Japan have all experienced similarly low increases in their human development scores.
