Question

The Human Development Index (HDI) was created by the United Nations (UN) to measure a country's level of development. Development is the process of improving the material conditions of people through diffusion of knowledge and technology. As the development process is continuous and constantly fluctuating, the HDI rating of any given country changes year to year. Categorization of development is simplified by terming countries as either developed or developing, based on what their HDI ranking is. A developed country has progressed further along the development continuum than a developing country and the UN considers these countries to have a very high development. A developing country has generally made some progress towards development but less than that of the developed countries. The UN further divides the developing countries into levels of "high", "medium", and "low" development.

The UN HDI considers development to be a function of three factors:

1.) A decent standard of living

2.) Access to knowledge

3.) A long and healthy life

Each country is given a score for each of the three factors, which are then combined into an overall HDI. The highest HDI possible is 1.0 (or 100%).

It is not surprising that the three most developed regions in the world according to the United Nations Human Development Index (HDI) are Australia, Europe, and North America. There are many regions of the world which have an overall low HDI ranking which is caused by only one or two of the factors considered in classifying rank. Which region of the world has the lowest HDI, mainly influenced by the low rank of the "long and healthy life" factor?

Answer

Sub-Saharan Africa has an HDI of only 0.4, the lowest of any region in the world. All other developing regions rank at a 0.5 or higher. Russia is the highest ranking of all the regions the UN deems as "developing" with an HDI of 0.72.

Why is Sub-Saharan Africa ranked so low? The answer is that their life expectancy is the shortest of anywhere in the world. There are many factors that cause the life-expectancy and overall health to be so low in Sub-Saharan Africa. The major cause for this is the AIDS epidemic which is a major crisis for this region of the world. Although the UN and other Government and Non-Government organizations have been helping with the AIDS crisis, it is still an incurable disease which has spread rapidly throughout Sub-Saharan Africa and continues to be the number one cause of death in this region. With many children being born with AIDS passed down from their parents, it is a challenge to get this crisis under control.

Lack of clean drinking water, lack of medical services, and minimal access to knowledge also influence the low life-expectancy and health in this region. With many people being contaminated with various diseases and viruses from their drinking water, combined with a shortage of medicines and medical facilities to treat patients in, unfortunately many people in this region die at a young age from otherwise curable illnesses. The minimal access to knowledge and low school attendance in areas that do provide education only worsens the problem as people are not educated on how to avoid getting sick and what to do to treat an illness. Providing access to education could prevent many deaths and help begin to contain the spread of the AIDS virus.
