The dots connecting hunger and pollution

Countries Analyzed

Interpretation

This dataset contains the Global Hunger Index for 140 different countries in the world from 1992-2015. The Global Hunger Index is measured by the IFPRI (International Food Policy Research Institute) with the following indicators:

• Undernourishment: the share of the population that is undernourished (that is, whose caloric intake is insufficient);
• Child wasting: the share of children under the age of five who are wasted (that is, who have low weight for their height, reflecting acute undernutrition);
• Child stunting: the share of children under the age of five who are stunted (that is, who have low height for their age, reflecting chronic undernutrition);
• Child mortality: the mortality rate of children under the age of five (in part, a reflection of the fatal mix of inadequate nutrition and unhealthy environments).

Data has purposely not been collected in higher income countries such as the US and countries in Europe.

Discussion

When looking at this visualization, use the slider in order to go through time and see how each country changes colors. You can notice some countries that have very large changes, such as Georgia in 1994, or North Korea which is one of the only countries to go up in the GHI. For the most part, most countries are advancing in reduce poverty and hunger all around the world.

Interaction

You may hover in order to retrieve the GHI score for a country by hovering over it. When clicking on a country on the map, the line is added to the grph on the right. This is intentional as there are many countries and just the countries with extreme alarming hunger index. You can select multiple countries to compare them side by side.

Visualization 2 (Prototype)

Interpretation

This data set records the number of pollutant particules such as PM10 and PM2.5 from all around the world. Then, I calculated the average for each country in order to analyze them.

Discussion

This visualization shows the average pollutant regions in the world, but you can notice that what could be analyzed here is how much of a certain region can be polluted. As much as regions such as China and the US pollute, their large amount of lands makes their average very low. Yet, we still countries that have high GHI are also regions of very largely polluted areas, but most importantly not as much as other countries in the world of same size. We can see that still India, many countries in the Middle East and Africa are affected by pollution as well.
