Global disparities in health form a complex issue adversely affecting much of the world's population. What has been found is that national income and other general socio-economic factors are strong determinants of population health (Houweling, 2005 & Schell, 2007). In countries where resources are less, people are much less healthy than people living in rich countries. In wealthier countries that have made immense progress in health indicators, the resulting change in age structure and morbidity and mortality patterns portends even greater financial demands on the health sector. This study noted the trends in several health indicators versus economic indicators and related it to low income, lower middle income, upper middle income and high income countries. We noted that there is improvement in all health indicators along with an increasing GNI per Capita and GDP. In low income regions though, the rate of improvement is slower as opposed to high income countries. However, there is progress, which is leading to an increase in aging population.
