At any time earlier than about 1000 AD, the material standard of living of almost every person was close to the minimum needed to sustain life. Societies in which the majority of the people attained a significantly higher standard of living have emerged only within the last two or three hundred years…

Improved material well-being resulted in substantially longer lives. Infant mortality (defined as death within the first year of life) declined, and the life expectancy of those who survived infancy rose. Malnutrition and its associated diseases became less common, and the mass killers, famine and plague, receded…

How has per capita output changed around the world over the last five hundred years? Worldmapper has answered this question by creating maps in which each country’s size is proportional to its per capita output…
