The Effect of Health Expenditure on Life Expectancy in South America

Introduction

In this page, it shows three maps. The first shows how life expectancy varies over time. The second shows how health expenditure varies over time. The third shows the the two vary over time. These maps can examine whether or not there is a relationship betweeen life expectancy and health expenditure in South America. It is also a previous work for studying how to efficiently use health expenditure.

Research Questions

1.How the life expectancy varis over time?

2.How the health expenditure varies over time?

3.How the life expectancy varies with health expenditure over time?

Data

Data source: World Bank

Time: 2005-2014

Data files: life expectancy , Health Expenditure and countries

Visualization Process

Use d3 and Brewer's color scheme.

Caveats

French Guinea is not included for lack of data.Multi-line charts are made using Excel.Firefox is suggested.Regression line is suggested but adding it makes the chart look a little messy.

Life Expectancy

This map is an animated choropleth map. The time period is from 2005 to 2014. When hover over a country, it also displays the correponding chart showing how the life expectancy changes. From this map, we can see that Chile has the largest improvement (2.86yrs) in this period while Guyana has the least improvement(0.82yrs).The two are also the countries with highest and lowest life expectancy.

Health Expenditure

This map is also an animated choropleth map. The time period is from 2005 to 2014. When hover over a country, it also displays the correponding chart showing how the health expenditure changes. From this map, we can see that Uruguay has the largest number while Bolivia has the least number.The two are also the countries with highest and lowest health expenditure increasement.Click to see corresponding multiline chart.

Life expectancy vs Health expenditure

In this map, it shows which country uses the health expenditure more efficiently over time. In other words, readers can tell which country uses less money but gains more improvement. It's clear that Bolivia uses health expenditure more efficiently. It also indicates there are some periods when health expenditure decreases but life expectancy increases.
