During 2018 Japan population is projected to decreased by -148,959 people and reach 126,087,131 in the beginning of 2019. The number of deaths will exceed the number of live births by 218,388, so the natural increase is expected to be negative. If external migration will remain on the previous year level, the population will be increased by 69,430 due to the migration reasons. It means that the number of people who move into Japan (to which they are not native) in order to settle there as permanent residents (immigrants) will prevail over the number of people who leave the country to settle permanently in another country (emigrants).
According to our estimations, daily change rates of Japan population in 2018 will be the following:
As of 1 January 2018, the population of Japan was estimated to be 126,236,090 people. This is a decrease of -0.12 % (-149,135 people) compared to population of 126,385,225 the year before. In 2017 the natural increase was negative, as the number of deaths exceeded the number of live births by 218,646. Due to external migration, the population increased by 69,512. The sex ratio of the total population was 0.950 (950 males per 1 000 females) which is lower than global sex ratio. The global sex ratio in the world was approximately 1 016 males to 1 000 females as of 2017.
Below are the key figures for Japan population in 2017:
Japan population density is 334.0 people per square kilometer (865.1/mi2) as of August 2018. Density of population is calculated as permanently settled population of Japan divided by total area of the country. Total area is the sum of land and water areas within international boundaries and coastlines of Japan. The total area of Japan is 377,930 km2 (145,920 mi2) according to the United Nations Statistics Division .
|Religion||Number of followers||Percentage of total population|
As of the beginning of 2018 according to our estimates Japan had the following population age distribution:
|- percentage of population under 15|
|- percentage of population between 15 and 64 years old|
|- percentage of population 65+|
In absolute figures (estimate):
We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.
Note: The pyramid provided is not corresponding to data given above because the age groups have different number of years.
As we can see the Japan population pyramid has a contracting type. This type of pyramid is more common for highly developed countries with low birth and death rates. Usually countries with such kind of population age distribution model have long life expectancy, high level of education and good health care.
Dependency ratio of population is a ratio of people who are generally not in the labor force (the dependents) to workforce of a country (the productive part of population). The dependent part includes the population under 15 years old and people aged 65 and over. The productive part of population accordingly consists of population between 15 and 64 years.
This ratio shows the pressure on productive population produced by the dependent part of population.
The total dependency ratio of population in Japan is 56.2 %.
What does this value mean? It shows that the dependent part of population is more than a half of the working part. It means that the working population (labor force) in Japan must provide goods for itself and cover expenditure on children and aged persons (this population is more than a half of working population). The value of more than 50% shows that the pressure on productive population in Japan is relatively high.
Child dependency ratio is a ratio of people below working age (under 15) to workforce of a country.
Child dependency ratio in Japan is 20.5 %.
Aged dependency ratio is a ratio of people above working age (65+) to workforce of a country.
Aged dependency ratio in Japan is 35.7 %.
Life expectancy at birth is one of the most important demographic indicator. It shows the number of years a newborn infant would live assuming that birth and death rates will remain at the same level during the whole lifetime.
Total life expectancy (both sexes) at birth for Japan is 82.3 years.
This is above the average life expectancy at birth of the global population which is about 71 years (according to Population Division of the Department of Economic and Social Affairs of the United Nations).
Male life expectancy at birth is 79 years.
Female life expectancy at birth is 85.7 years.
