Japan, as you know, the country of centenarians. The number of centenarians in the country is steadily growing. Over the past year the index rose by 4.4 thousand people. Scientists take into account only the people who crossed the threshold of 100 years.
To a ripe old age, say the experts, live 87% of Japanese. The country has a serious tendency to ageing, the number of pensioners is growing, and fertility rates remain relatively low.
In Japan, the number of adolescents under the age of 15 years is 13% of the total number of citizens, while those over 65 years make up one quarter (25 %) of the total population.
Similar data are typical not only for Japan but for the most developed countries of Europe.
