However, its availability over time was limited until then. Three different versions of the RCI are then applied to the measurement of the impact of oil companies on local communities in the Niger Delta Nigeria and to national surveys Afrobarometer.
The HDI utilises four key metrics 1 : life expectancy at birth to assess a long and healthy life ; expected years of schooling to assess access to knowledge ; average years of schooling to assess access to knowledge ; gross national income GNI per capita to assess standard of living.
Countries which lie below or closer to the grey line which indicates equal parity between these measureshave achieved improvements in these measures of development health and education with lower levels of GDP per capita relative to countries further from the line.
The Ferdi has worked over the last years in collaboration with the UN-DESA to build retrospective series of this index allowing to follow improvements in this domain and for research purposes. Time series are also usually incomplete. Once each of the individual indices have been calculated, they are aggregated to calculate the HDI.
Aggregating the four metrics to produce the HDI.
Click to open interactive version HIHD vs. The authors provide an axiomatization of a family of multidimensional indexes that fills the gap between theories of justice and poverty measurements.
The Ferdi has benefited from a huge work of reconstruction of annual data series covering the period until now, for under-5 mortality rate and fertility in Sub-Saharan countries by Michel Garenne, research director at IRD.
However, if we look at changes through time, we see that although HIHD values are typically lower, they can change much more quickly since indices are derived non-linearly on a logarithmic scaling. They are: life expectancy at birth to assess a long and healthy life ; adult literacy percentage of the population aged over 15 years who can read and write ; educational enrolment rates percentage of population in the relevant age cohort enrolled in primary, secondary, and tertiary education ; gross domestic product GDP per capita to assess standard of living.
