Snapshot: The demographic diversity of the World
Fifty-five per cent of the world’s people live in countries whose birth rates guarantee indefinite future growth. Nearly one billion people live in countries – Afghanistan, Iraq, Nigeria, Pakistan, the Palestinian territories, Somalia and Sudan among others – in which fertility averages four or more children per woman. Assuming no changes in family size or life expectancy, these countries’ populations will double in fewer than 35 years.
Simultaneously, population aging and decline have risen in prominence on the public policy agenda in many regions. Nearly 45 per cent of the world’s people live in countries in which the average family size is below the number needed over the long term (usually slightly more than two children per woman) to avoid population decline.  Most of these countries are developed, but not all – among them are Chile, China (with 1.3 billion people), Iran, South Korea and Thailand. Population decline has not yet begun in most of these countries and is likely to proceed gradually when it does, in contrast to the still-rapid pace of growth in the dozen or more fastest-growing national populations. So far, despite fears about its future impacts, population aging has not caused demonstrable harm to the economy, security or environment of any country.
