Countries that are in the postindustrial phase of demographic transition include most developed countries such as USA, Canada, Japan, Australia, and many countries in Europe. These countries have low birth rates, low death rates, and stable or declining populations due to advanced healthcare, education, and economic opportunities.
Countries with the lowest natural increase rates typically have low birth rates and/or high death rates. As of a 2021 United Nations report, countries like Bulgaria, Latvia, and Japan have some of the lowest natural increase rates in the world.
Countries that are in stage 4 of the demographic transition model are typically more economically developed with low birth rates, low death rates, and a stable or declining population growth rate. Some examples of countries in stage 4 include most Western European countries, Japan, Canada, and Australia.
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 proper sequence in the demographic transition model is: Stage 1 - high birth and death rates, Stage 2 - high birth rates and declining death rates, Stage 3 - declining birth rates and low death rates, Stage 4 - low birth and death rates, and some scholars also recognize a Stage 5 with very low birth and death rates.
Demographic transition
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.
The Demographic Transition Model (DTM) has four stages: Stage 1 (high birth and death rates), Stage 2 (high birth rates and decreasing death rates), Stage 3 (decreasing birth and death rates), and Stage 4 (low birth and death rates). Some models include a hypothetical Stage 5 with very low birth rates and an aging population.
