Understanding Mega variables with dynamic stats: Gap Finder

"Everybody is entitled to his own opinion, but not to his own data"

Rep. Daniel Moynihan, 1970

"If you can name it, you can measure it"

Roger Kaufman


Research-based theory and practice requires concepts to be measurable in quantitative terms.

Gap Finder, a Website created by Prof. Hans Rosling can be a useful tool to that end-




Gap Finder presents global statistics in dynamic graphs and tables as shown in the video that starts this article.

Gap Finder graphs allow you to combine two or three variables -such as in the following example are life expectancy and per capita GDP at Power Purchasing Parity (PPP) and see how these indicators evolve in time series, combining them with a third variable -such as population or GDP- visually represented here as a circle area.

You can compare the evolution of almost 120 countries -as we did here with Argentina, Brasil and Chile- and visualize trends very easily


I invite you to explore the site and to check this video that summarizes 200 years of social evolution among 120 countries in 4 minutes
