                  The poverty gap is a ratio showing the average shortfall of the total population from the poverty line—the minimum level of income required to secure the basic necessities for survival. In other words, it reflects the intensity of poverty in a nation. The poverty gap indicator is produced by the World Bank Development Research Group. It measures poverty by looking at household per capita income and consumption.  The World Bank says it needs to measure all people against the same standard. As such, it sets an international poverty line at periodic intervals, calculating the cost of living for basic food, clothing, and shelter around the world.  In 2015, this threshold was updated from $1.25 to $1.90 per day. It is difficult to set a common international poverty threshold since different countries have different thresholds for poverty.
