underpopulation problemとは 意味・読み方・使い方

The Oki islands are located in the Sea of Japan approximately 60km from the coast of Shimane Prefecture. Owing to their distinctive isolation, the islands suffer the dual problem of accelerating underpopulation and increased population aging. The total population has now declined to 2,400, and only ten babies a year are born on the islands.例文帳に追加
