Check out this graph.
The graph is displaying the contraceptive use of women (% women aged 15-49) vs. HIV infected (% adults aged 15-49). Africa is heavily concentrated toward low contraceptive use with a tremendous HIV infection rate. Strangely, during 2006, the statistics for the USA and other european nations disappear off the map. The year 2000 shows a pattern of contraceptive use vs. HIV infection. Towards the lowest 20% use of contraceptives by women who use contraceptives, Sub-saharan Africa stands on the lowest percentile with the highest HIV infections. Zimbabwe in 1984 had a 6% HIV infected population which rose to over 28% by 1997. Interestingly, after the contraceptive use percentile by women began to rise above 50%, the number of HIV infected persons dropped drastically to around 19% by 2005.
The indicators are contraceptive use of women (% women aged 15-49) on the X-axis vs. HIV infected (% adults aged 15-49) on the Y-axis. These indicators show a pattern of the use of contraceptives alongside a nation´s HIV infection percentile. These indicators prove a correlation between a nation´s state of general health. It allows other neighboring natins to become aware of the health situation in nations that suffer from prominent HIV infections. However this graph does not take into account the innocent children who become infected after drinking the breast-milk of their infected mother. It also does not provide information for most nations such as the USA or European Union after 2005. These are important indicators of human development as it shows the progress of nations all over the world towards good health.
