Increase in birth rate in developed countries

Reversal of the falling birth rate in «rich» countries.
Until recently, considered self-evident that the developed, rich countries are plagued by low birth rates, and developing / underdeveloped characterized by extremely high birth rates.

A U.S. investigation which saw the light of day Wednesday, this is not true anymore, as Australia, Sweden, France, the U.S. and Britain - the most developed countries in the world - experiencing «explosion» in pace births, a phenomenon which, if continued, will have beneficial effects for the treatment of «aging» of the population of the developed world.

As demonstrated by the calculations of the U.S. Census Bureau, the number of persons whose age exceeds 65 years on the planet, will exceed 1.3 billion in 2040 - when today amount to 500 million.

«Our findings are very important in assessing the future of the population of humanity ... and cast new light on our understanding of the 21st century» refers to the research, published in the prestigious British scientific magazine «Nature».

Many developed countries have fallen below the birth rate needed to maintain a stable population (2.1 children per woman). It is considered that maintaining the present birth rates, countries like South Korea, Japan, Italy and Spain (1.08, 1.26, 1.32, 1.33 children per woman respectively) are found in 50% of the population within a space 40-45 years. However, according to new research, this phenomenon was reversed when a country reaches a certain point of development, the birth rates start to rise.

Research scientists, led by Mikko Mirskila the University of Pennsylvania, discovered that there is a «fundamental change in the generally accepted (in theory), 'negative' relationship between births and living standards».

The reasons vary: higher incomes, more conveniences, living standards attained in general conditions that «make it more likely that women and couples in general, can afford the financial costs of children» said Professor Sripant Toultzapourkar University Stanford-while the same factors in many developing countries (where 5.6 children per woman is the average) acts as a deterrent, reducing the numbers of births.
