What makes government effective? Is it measured by the happiness level of the citizens, their health, or simply by economic success?
One measure called the Human Development Index(HDI) is calculated yearly by the United Nations based on the health of its citizens along with their level of education and standard of living and provides a standard, regularly tracked metric which can be used to measure the effectiveness of government over time.
Based on their HDI, countries are broadly classified into four categories as low HDI, medium HDI, high HDI and very high HDI.
This visualization aims to provide a better understanding of the relationship between HDI scores with various direct as well as indirect factors.
Since HDI is directly affected by health and education of the citizens, spending on health and education have been included as the direct factors, whereas four measures of governance namely, "Political Stability & Absence of Violence", "Government Effectiveness", "Regulatory Quality" and "Rule of Law" have been chosen as the indirect factors.
Using the visualization, we can therefore explore questions such as whether countries with a higher HDI spend more on health and education than their lower HDI counterparts, and whether countries with higher HDI enjoy better governance.
Each country is represented as a single slice of the circle. Values increase towards the outer edge of each circle and decrease towards the center.
Governance indicator values are on a scale from -2.5 to 2.5. Values progress from 0 to 2.5 in case of good governance and from 0 to -2.5 in case of bad governance. Each bar shown in the visualization represents upto 0.5 points.
Hovering over any section shows the relevant data values for that country slice. Clicking on any two countries shows a comparison of their values.
The 56 countries with a very high HDI cover the largest area of land on the planet. However, due to these including some very sparsely populated areas, they have less than a fifth of the world's population. In contrast, the 42 countries with medium HDI cover less than 15% landmass, but house over a third of the population.
