UN releases latest world population analysisSome highlights:
The report indicates that world population reached 6.5 billion in 2005 and that
the world’s population could ultimately stabilize at about 9 billion people.
Considerable diversity exists in the expected population growth of countries. The
population of many countries, particularly in Africa and Asia, will increase greatly in
the coming decades. In contrast, owing to below-replacement fertility levels, some
developed countries are expected to experience significant population decline. Half
the world’s population is expected to live in urban areas by 2007. Although the
number of very large urban agglomerations is increasing, about half of all urban dwellers
live in small settlements with fewer than 500,000 inhabitants. The
proportion of older persons is expected to continue rising well into the twenty-first
The number of migrants more than doubled between
1960 and 2000. Affecting countries of origin, transit and destination, international
migration is in the forefront of national and international agendas.
High mortality is the most significant population concern for developing
countries. The most significant demographic concern of the developed countries
relates to low fertility and its consequences, including population ageing and the
decline in the size of the working-age population.
