Before there is to see an interesting story, in fact, it is systems thinking. In 1967, Romania believes that the need to increase their population, so the introduction of a blunt policy, prohibiting abortion for women under the age of 45. Soon, the birth rate has tripled.
But after a period of time later, the birth rate fell back to its original level. In addition, due to the large number of dangerous illegal abortions, women of childbearing age before death rate has tripled compared. Some poor families because they can not raise more children.
In Hungary, Romania implement the same period of the ban, also plagued by low birth rates, the introduction of a modest rewards program: larger families can have bigger houses, and finally played a less obvious but quite positive effect.
Back in the 1930s, Sweden's birth rate fell sharply. Interestingly, with Romania and Hungary are not the same, Sweden believes that the number of households compared to the population, the quality of parenting is more important.
Subsequently, Sweden issued a series of policies to support the improvement of national childcare standards, including support for families in need, increase investment in education and health care, and so on, at the same time, also reserved the right to free contraception and abortion people.
A population growth of the country is a complex system. The so-called system is one element of a set of interconnected constituted, can achieve an overall goal. Large ecological environment, the economy, financial markets, as small as a convenience store, a temperature regulator, a person's fitness habits ...... can be seen as a system. We can say that we live in an all-encompassing system network every day.
The system intervener different understanding of systems, which use different means of intervention will cause the results vary widely, and some can well achieve the intended purpose, but some suffered retaliation system, which also and we have to see whether the entire system, to make a decision about, for a country, a right decision, invaluable.
