family planning groups are blaming the internet, charging that fertile men and women are spending too much time online, and not enough having sex.
Demographic transition
There are a few countries with birth rates of zero, and other countries with negative birth rates. Countries that have a birth rate of zero include, but are not limited to, Japan; Poland; and Slovakia Go to the link below to find more birth rates.
The tendency of a population to shift from high birth and death rates is called a demographic transition.
The ten countries with the highest birth rates are on the continent of Africa. The country with the highest is Niger
Birth control, education. (And Condoms)
Demographic transition
As the population ages, there will be a smaller proportion of people of working age who are supporting those that are too old to work. In many Western countries with low birth rates, this has pushed back the age at which people can retire. Furthermore, many countries had a state pension system under which some of the tax paid by today's workers went towards the pensions of those that are retired. Low birth rates results in a increase in the dependency ratio: there is an increasing number of retired people depending on each worker.Furthermore, if the birth rate falls below the replacement rate, the population will gradually die out.
Emigration.
Demographic transition
Developing countries have high rates of natural increase as their birth rates are high, and although their death rates are also high there is usually a big gap between the two figures. Malawi's natural increase is 30 per year for every 1,000 people. This is calculated from the Birth Rate of 51 minus the Death Rate of 21 (51 - 21=30). Developed countries have both a low death rate and low birth rate, with only a small gap between the two. Norway's natural increase is 3 per year for every 1,000 (14 - 10=3).
No, Africa does not have the lowest birth rate and infant mortality rate in the world. African countries often have higher birth rates and infant mortality rates compared to other regions due to various factors such as inadequate healthcare infrastructure and high fertility rates.
There are many factors that lead to low birth rates. One factor is urbanization, which usually means better access to family planning services and less need for children in the work force. Another factor is the cost associated with raising and educating children. Educational and employment opportunities for women are often a factor. A low infant mortality rate in an area also leads to low birth rates.
