Tongas 1985 population of 109,000 is projected to grow to 177,000 by the year 2025. Urban population will increase from 19.7% in 1985 to 43.9% overall by the year 2025. No specific data are presented on population age structure and growth, mortality, morbidity, fertility, and international migration. Low immigration, high emigration, and spatial distribution are nonetheless considered to be acceptable by the government, while high population growth, fertility, and mortality and morbidity are not. Tonga has an explicit population policy. It aims to lower population growth and fertility through maternal-child health, family planning, and population education programs. The government is also interested in stemming internal migration from the outer islands to Tongatapu. Population policy as it related to development objectives is discussed, followed by consideration of specific policies adopted and measures taken to address above mentioned problematic demographic indicators. The status of women and population data systems are also explored.
