The demographic features of the population of Japan include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects regarding the population. Based on the census from October 2010, Japan's population was at one of its peaks – 128,057,352. As of March 2012 the population estimate was 127,650,000〔See links to the Census and the monthly Population Estimate through the (Japan Statistical Agency ) homepage.〕 making it the world's tenth-most populous country at the time. However, both the United Nations Population Division and the Population Reference Bureau estimated that Mexico overtook Japan in terms of population by mid-2015. Current statistics do not indicate much difference in population numbers.〔(Statistics on the total population in Japan ), International Monetary Fund. April 2013. Retrieved June 26, 2013.〕 Japan's population size can be attributed to high growth rates experienced during the late 19th and early 20th centuries. In recent years, Japan has experienced net population loss due to falling birth rates and almost no immigration, despite having one of the highest life expectancies in the world at 81.25 years of age as of 2006.〔(CIA - The World Factbook - Rank Order - Life expectancy at birth )〕 Using the annual estimate for October of each year, the population peaked in 2008 at 128,083,960 and had fallen 285,256 by October 2011.〔Japan Statistical Agency monthly Population Estimate.〕 Japan's population density was 336 people per square kilometer. Based on 2012 data from the National Institute of Population and Social Security Research, Japan's population will keep declining by about one million people every year in the coming decades, which will leave Japan with a population of 86 million in 2060. By that time, more than 40% of the population is expected to be over age 65. In 2012, the population had for six consecutive years declined by 212,000, the largest drop on record since 1947 and also a record low of 1.03 million births. In 2014, a new record of population drop happened with 268,000 people. In 2013, more than 20 percent of the population are age 65 and over.〔(【引用サイトリンク】title=Japan's population falls by record 244,000 in 2013 )〕 The population ranking of Japan dropped from 7th to 8th in 1990, to 9th in 1998, and to 10th in the early 21st century. In 2015 it dropped further to 11th place, according both to UN and PRB. ==Population== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Demographics of Japan」の詳細全文を読む スポンサード リンク
