1. The causes of the gap
The development gap relates to global inequality
Around 2.8 billion people live on under $2 per day (‘moderate poverty’)
Some 1.1 billion people live on less than $1.25 per day (‘extreme poverty’)
Over time a greater proportion of wealth has concentrated in the hands of the richest 20% of people, compared to the poorest 20% of people (see graph)
Since 1980, the percentage of people living in extreme poverty has fallen from 40% to 20% of world population, but because of population growth the total number of people is extreme poverty is still very high.
