Tunisia's 1985 population of 7,261,000 is projected to grow to 13,284,000 by the year 2025. In 1985, 39.6% of the population was aged 0-14 years, while 6.0% were over the age of 60. 22.5% and 13.1% are projected to be in these respective age groups by the year 2025. The rate of natural increase will have declined from 25.3 to 10.2 over the period. Life expectancy should increase from 63.1 to 75.0 years, the crude death rate will decrease from 8.4 to 5.9, while infant mortality will decline from 71.0 to 16.0. The fertility rate will decline over the period from 4.9 to 2.1, with a corresponding drop in the crude birth rate from 33.7 to 16.0. The 1983 contraceptive prevalence rate was 41.1, while the 1984 female mean age at 1st marriage was 24.3 years. Urban population will increase from 53.0% in 1985 to 72.6% overall by the year 2025. Insignificant immigration is considered to be acceptable by the government, while the high population growth, mortality, fertility, low emigration, and spatial distribution are not. Tunisia has an explicit population policy. It aims to lower the birth rate and population growth, extend family health services in rural areas, improve living conditions and health care facilities for infants and small children, decrease migration to metropolitan areas, and adjust the spatial distribution pattern. 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.
