To ensure their future, demographers say a country needs a fertility rate of more than two Children per woman to achieve the fertility rate ("The number of births per thousand women of childbearing age in a year," according to Wikipedia) Required.

However, the conjunction of a number of economic, social and cultural forces makes only half of the 224 Countries in the world reach the fertility rate to ensure generational replacement.

Countries struggling to change the sign of their demographics: Several countries are using strategies of the most varied to reverse this trend.

Denmark

The Danish government is using the strategy of appealing to patriotism to encourage couples to have children. Literally, it has undertaken a campaign called "do it for Denmark." On the other hand, the low fertility rate of the Nordic country, 1.73 children per woman, has led the Danish travel agency Spies Rejser to propose an ingenious initiative leading women to become pregnant. He has offered three years of baby supplies in exchange for conceiving children on booked vacations with this travel agency.

In addition, he has started a campaign called "Do it for Mum" that instigates in couples a guilty feeling for Let them give their mothers a grandson.

Russia

It is experiencing the perfect demographic storm: men die young (AIDS and alcoholism are making a dent in the country) and women are not having babies. So serious seems the problem that in 2007 Russia declared December 12 the official day of the Conception. That day is a holiday for people to focus on having children. Those women who have a child nine months after that day earn a refrigerator.

Japan

Japan's fertility rate far from being at the replacement limit since 1975. To reverse that trend, in 2010 a group of students from Tsukuba University introduced a baby robot called Yotaro which gives parents an idea of what is the paternity.

These students assume that both men and women begin to see themselves as potential fathers and mothers as they will be emotionally prepared to get to it.

Singapore

It has the lowest unit rate in the world, 0.81 children per woman. This alarming situation led the Singapore government to celebrate on August 9, 2012, the "National Night", which was intended to encourage couples to "allow their patriotism to explode."

On the other hand, the country has put a limit on the number of floors of a room for rent with the apparent purpose of encouraging people to live together and procreate. Each year the government spends about $ 1.6 billion on programs to get people to have more sex.
