Ceorana Department of State Human Development Index

The Ceorana Department of State Human Development Index, or CHDI is a formula developed by the Ceorana Department of State to rank nations by their "human development". The rankings are published approximately monthly. Although a rough formula is available to all, the only "official" rankings are the ones published by the Ceorana Department of State.

The Formula

The CHDI is calculated in three parts, the first two helping to determine the third. Since NationStates forbids nations to tell other nations statistics such as GDP, literacy rate and life expectancy, the CHDI makes educated guesses using numbers that are given. The final CHDI is the three indices averaged.

The first part is the GDP index. It is calculated by dividing the approximate logarithm of the GDP/Capita minus the theoretical minimum GDP/capita by the difference of the theoretical maximum and theoretical minimum GDP/capita numbers.

The second part is the Education index. It is derived from the literacy rate, which is approximated using the amount of education spending as well as the proportion of education spending and GDP/capita.

The last part is the Life Expectancy index. It is calculated by dividing the difference of the nation's life expectancy and 25 by 60.

Life expectancy is calculated using the average of the previous two indexes as well as healthcare spending numbers.

List of Nations by CHDI

The following rankings are the official April 2006 rankings. Although normally, the numbers show the changes since the last ranking, the rating system has undergone a significant change since March's rankings, so those numbers are not applicable.
