World population trends

World population in 2015 = 7.3 billion

Worldwide average life expectancy in years = 71 (men 69; women 73)

Worldwide average gross income (before taxes) per person per year = $15030 (developed countries $39020; underdeveloped countries $2270)

Note that these averages are skewed by the incomes of the ultra-rich persons. The median incomes are much lower. You have to see the distribution of incomes to appreciate this statistical fact.
