This project will try to get answers from a dataset containing five variables :
- the observed country (
country
) - the year of observation (
year
) - the Gross Domestic Product (
gdp
) - the life expectancy at birth of its citizens (
life_exp
) - the perceived health of the population (
perceived_health
)
At first glance, we wonder how such little data can give us interesting insights. Still, if we look a little closer, this little data might have to say some quite unusual things, opposite to media mainstream. That is : GOOD NEWS ! That's what I intend to do : see if these data might contain some happy news about world's evolution trend.
I will ask the 3 following question to the data :
- is life expectancy getting better in every country ? if not, how many countries are left behind ? is the number of leftovers increasing or decreasing over time ?
- is the population feeling better over time ?
- what relationship can we establish between objective wealth and subjective well being over time ?
