    Abstract:
    World population growth was very slow throughout most of history, with the 1 billion mark attained only in the 19th century. Total world population reached 5.848 billion in 1997, and at a growth rate of 1.4% is expected to reach 8 billion in 2025. Over 80% of the growth occurs in developing countries. Asia, with 3.538 billion, remains the most populous continent. 1.243 billion are in China; 960 million, in India. Population growth appears to be declining everywhere in the world expect Africa, which is growing at 2.6%, and Western Asia, growing at 2.2%. The growth rate is 0.3% in industrialized countries as a whole, and 0% in Europe. The developing countries have crude birth and death rates of 29/1000 and 9/1000, respectively, compared to 12/1000 and 10/1000 in developed countries. Life expectancy at birth is 63 in developing countries, 50 in East and Central Africa, and 74 in the industrialized countries. Nearly all regions have entered the demographic transition, but they are at very different stages. As demographic trends diverge, the gap in economic development between developed and developing countries is widening. According to the 1996 World Report on Human Development, only 21.7% of the world's gross national product originates in developing countries. The differences are enormous in the degree of satisfaction of basic socioeconomic and health needs. It has become clear that demographic pressure is a determining factor in environmental degradation. Climatic disturbances, water pollution, deforestation and desertification attest to overconsumption of resources and emission of enormous quantities of wastes. Policies to control demographic growth have become the pivot of processes for construction of healthy societies. All studies have shown that issues of population, resources, and the environment are organically linked. Tunisia, a progressive country, has been concerned since independence with economic growth and social advancement of the population, and population has been integrated into the different social and economic plans. Economic conditions have improved, and the principal demographic and health parameters are increasingly under control. Tunisia has achieved a contraceptive prevalence rate of 60%.
