Seven reasons the world is improving

Julius Probst at BBC gives seven reasons the world is improving:

1. Life expectancy continues to rise: up from 29 to 71
2. Child mortality continues to fall: down from 22% to 4.5%
3. Fertility rates are falling: from around 5 per woman to 2 meaning global population will stabilise
4. GDP growth has accelerated in developed countries: real incomes double every 36 years
5. Global income inequality has gone down: hundreds of millions have been lifted out of poverty and for first time in 200+ years over half the world are now “middle class”
6. More people are living in democracies: gone from 0.9% to 53%
7. Conflicts are on the decline: there has been no war between great powers since Vietnam
