× Info! Below visualization shows Top 30 countries for selected year.
We have considered 3 factors for calculation: Population, GDP and Life Expectancy of the country on the selected year.
Formula: We've used Harmonic Mean to calculate the score for each country. Then updated the Harmonic Mean field in "Gapminder_All_Time_mean.csv" file.

3 * Population * GDP * Life Expectancy
Score = ------------------------------------------------------------
(Population + GDP + Life Expectancy)

Why we used HM As value of Population is very high in comparison to GDP and Life Expectancy, usage of Arithmetic Mean (AM) or Geometic Mean (GM) would give unbalanced score (more towards the Population of the country). In our opinion, HM gives most balanced score with all the three parameters.
