Question

when was life expectancy variation in countries first recognised? (for example: is it an acute situation or has it been developing for some time ? was it first identified in a specific country?

Answer 1

Answer. Life expectancy variation means the variations or the gap between the life apns of male and females. It was recognised in the years of 1990's when the epidemic diseases prevailed. It was initially recognised in Africa due to Aids and little later in Eastern Europe due to the fall of Soviets. This variation says that women live longer than men, in all around the world. The ratio of the life expectancies of females to males is 1:3, but slowly it is altering. The life expectancy of male is also getting better and the globally the increase is of 5.5 years. Many efforts are being made by Who, since then, like by bringing improvements in child survival or by providing all the basic and needful treatments to the new borns or in prenatal cases, etc.
