Another finding was that fertility rates have declined in those parts of Morocco and Turkey that export labour to Europe.

Fertility rates tend to drop with economic development. China's is still above that of Britain and many European countries.

Some demographers, however, argue that plummeting fertility rates and a rapidly aging population are reasons enough to ease the rules.

Italy has no more childless women than France and Sweden, countries with much higher fertility rates (see table).

But whatever the cause, it seems to mean fertility rates can overshoot downwards.

Demographers used to say that fertility rates only fell when women got educated and the economy got rich.

With fertility rates crashing in Asia and Latin America, half of the increase in population over the next 40 years will be in Africa.

Compared with America, even the growing parts of the continent have modest fertility rates and high dependency ratios.

And Mr Daly argues that it would not reduce fertility rates, as some people may fear.

The ageing of the world's populations is the result of the continued decline in fertility rates and increased life expectancy.

World population can be stable only if fertility rates around the world average out to 2. 1 children per woman.

Some religious sects had fertility rates three or four times the general population, he noted.

Rural fertility rates are believed to be higher than China's statistics show, since many children are concealed from census takers.

He says that both life expectancy and fertility rates have changed dramatically over the last 60 years, and further changes are expected.

Doctor Murray says lower fertility rates around the world, combined with higher earnings, are also reducing deaths.

The fertility rates, cleavage rates, hight quality embryo rates and pregnancy rates were compared between the two groups.

The delay in marriages induced by the stipend subsidy arguably contributed to lower fertility rates and child mortality rates in Bangladesh.

Over the same period, the populations of OPEC countries started to mushroom, as both life expectancy and fertility rates rose.

In recent decades, many countries have made progress in reducing maternal mortality and lowering fertility rates.

Demography is on France's side: its population is growing, whereas Germany has one of the EU's lowest fertility rates.

Initial shocks from a relaxation of birth quotas may cause an upsurge in fertility rates in the early years.

The target reductions in fertility rates were reached long ago. Current rates, he says, are below replacement levels and are unsustainable.

Even so, the tigers' declines in fertility rates have been astonishingly quick.

Having said that, it's impossible to overlook the correlation between poverty and alarmingly high fertility rates.

The cause for the slowdown is declining fertility rates.

For a start, high mortality and fertility rates are related.

High fertility rates, along with inadequate health care, impede development and economic growth.

In most Western democracies, fertility rates have plummeted as wealth has increased.

Given that local fertility rates are falling, both hubs hope to continue to fuel that boom via immigration.

In others like England, Ireland and Italy, the rising fertility rates were interrupted.

Much of Europe and East Asia have fertility rates far below replacement levels.

In rising powers, higher fertility rates go hand in hand with greater faith in collective destiny.

Japan, South Korea, China, Taiwan, Singapore, Thailand, and even Vietnam all have fertility rates well below par.

In a few countries where fertility rates are already very low, such as Japan and South Korea, they are still falling.

In most of the world, fertility rates have fallen because couples want fewer children.

Africa's fertility rates are falling. Can the continent take advantage?

But the rock-bottom fertility rates in the tigers give the problem particular potency.

Admittedly, Africa is lagging behind Asia by about 20 years, and the continent's fertility rates are still high, but the trend is clear.

Dramatic declines in fertility rates in some countries and high rates in others pose a critical challenge.

Despite a tiny uptick in fertility rates in some European countries, the birth dearth continues.

Marriage and fertility rates have plunged.

They usually have extremely high fertility rates: most of the countries with fertility rates over 5. 0 are fragile.

There are lots of social explanations of why fertility rates fall as countries become richer.

Much poorer countries, such as Burma, have very low fertility rates nowadays, even without state birth restrictions.

Africa's fertility rates are falling.

And the one proven way to reduce fertility rates is to empower young women by educating them.

All the countries with fertility rates over 5. 0 are in Africa (with the one exception of Yemen).

That is one reason why their fertility rates have fallen.

The lowest fertility rates were in April and May, with 1. 92 and 1. 93 for each woman.

This is why in previous projections the UN assumed fertility rates in all countries would eventually fall to 1. 85.

But even in the remaining, poorer, half of the world, fertility rates have come down spectacularly, from 5. 2 in 1970-75 to 2. 6 now.

At the same time, low fertility rates in Japan and many European nations have raised concerns about labor shortages.

In Hong Kong, for example, a cohort of 1, 000 women would be expected to give birth to just 547 daughters, at today's fertility rates.
