Japanese researchers on Friday unveiled a population clock that showed the nation's people could theoretically become extinct in 1,000 years because of declining birth rates.
日本研究人員上周五發布了一個人口倒計時鐘，該時鐘顯示，由于出生率持續下降，理論上日本人將于1000年后滅絕。
Academics in the northern city of Sendai said that Japan's population of children aged up to 14, which now stands at 16.6 million, is shrinking at the rate of one every 100 seconds.
日本北部城市仙臺的學者稱，日本14歲以下兒童人口目前為1660萬，正在以每100秒1個的速度減少。
Their extrapolations pointed to a Japan with no children left within a millennium.
學者們的推斷指出，日本在1000年后將沒有兒童。
"If the rate of decline continues, we will be able to celebrate the Children's Day public holiday on May 5, 3011 as there will be one child," said Hiroshi Yoshida, an economics professor at Tohoku University.
日本東北大學的經濟學教授吉田浩說：“按這種下降速度，到3011年5月5日我們將剩下一名兒童，仍能慶祝兒童節。”
"But 100 seconds later there will be no children left," he said. "The overall trend is towards extinction, which started in 1975 when Japan's fertility rate fell below two."
他說：“但再過100秒，日本將沒有兒童。自從1975年日本生育率降到每名育齡婦女兩個孩子以內，走向滅絕便成了總體趨勢。”
Yoshida said he created the population clock to encourage "urgent" discussion of the issue.
吉田說他創立這一人口鐘是為了鼓勵人們“緊急”開展關于這一問題的討論。
Another study released earlier this year showed Japan's population is expected to shrink to a third of its current 127.7 million over the next century.

Government projections show the birth rate will hit just 1.35 children per woman within 50 years, well below the replacement rate.

Meanwhile, life expectancy — already one of the highest in the world — is expected to rise from 86.39 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men.
與此同時，日本已然是世界第一的人口壽命將進一步延長。日本女性的平均壽命將從2010年的86.39歲增加到2060年的90.93歲，而日本男性的壽命將從2010年的79.64歲增加到2060年的84.19歲。
More than 20 percent of Japan's people are aged 65 or over, one of the highest proportions of elderly in the world.

Japan has very little immigration and any suggestion of opening the borders to young workers who could help plug the population gap provokes strong reactions among the public.
