Birth rates in the European Union are falling fast.
In the first of a series about motherhood and the role of the state in encouraging couples to have more children, the BBC News website's Clare Murphy asks why governments are so concerned about the size of their populations.
William The Conqueror was counting people nearly 1,000
years ago, and his European descendants are still at
it. Small, today's politicians contend, isn't
Europe's working-age population is shrinking as fertility rates decline. In a fit of gloom, one German minister recently warned of the country
"turning the light out" if its birth rate did not pick up.
No EU country has the 2.1 birthrate needed to keep a population stable
Efforts to encourage couples to breed have a chequered history and, for many, recall fascist pasts. Mussolini heavily taxed single men in his Battle for Births, Hitler awarded medals to women with large families in his quest for a superior German race.
No-one is yet berating bachelors or mooting medallions
for multiple births. But Europe's many governments are scrambling to find a solution.
Demographic decline causes anxiety because it
is thought to go hand-in-hand with economic decline.
With fewer, younger workers to pay the health and
pension bills of an elderly population, states face an unprecedented fiscal burden.
The dependency ratio of those aged 65 and over to those of working age looks set to double from one-to-four to one-to-two in 2050.
How can Europe, which increasingly sees itself as a counterweight to US hegemony, claim equal status when it is being outpaced by American population growth?

If current forecasts prove correct, then the US - which currently has 160m fewer people than the EU - will have equalled it by 2050.
Increasing immigration is, in theory, one
option for Europe, but most agree it is politically
unfeasible in the current climate.
Others stress that it would not in any event solve the problem in the
longer term - the migrants would themselves grow old
and their own fertility patterns would start to match
those of the country which received them.
Another option is to increase the productivity of the working population, drawing more people into the workforce - and more controversially - making them stay there longer. But moves to raise the retirement age tend not to play well with electorates.
That leaves boosting birth rates.
Some analysts believe the fears are exaggerated. It
seems richly ironic, they argue, to be worrying about
falling numbers of people and, at the same time, to be
fretting about the drain on natural resources, and the
jostle for living space.
In addition, women's ability to control the number of
children they have is a positive development, freeing them from a life of ongoing
Those who want to boost the birth rate do not
necessarily disagree on this last point.
But, they wonder, are women restricting the size of families
through free choice - or because financial concerns
and worries about their position at work prevent them
from having as many children as they might like.
Many European countries already have policies in
place - some more explicitly pro-natal than others.
Sweden, stressing gender equality rather than stating
directly that it wants to boost birth rates, provides
a mixed package of higher pay for women, flexible
working for both parents and high quality childcare.
France, meanwhile, is positively proud of its avowed pro-natalism, providing a series of tax and cash incentives for those having babies.
Who will support an ageing populace?
Other countries have also started toying with the idea of straight payments. Poland, where the population has fallen by half a million in the last six years, has recently passed legislation that will see women paid for each child they bear.
In Italy, where the population could shrink by as much as one third by 2050, one town has started offering couples 10,000 euros for each newborn baby.
How successful cash is as an incentive is still unclear. One study suggests that, even when cash allowances are boosted by 25%, the fertility rate climbs just marginally - perhaps by as little as 0.6%.
And the impact of generous maternity leave schemes and state-subsidised child care has also yet to be fully established.
Swedish and French birth rates may be higher than in
much of Europe, but despite their respective systems,
both countries still lag behind the holy grail of 2.1
children per woman needed to keep a population
Europe is still feeling its way in this area, and
may, some say, have to come to terms with the fact
that there are women remaining childless or having
small families by choice.
Recent evidence from Germany suggests that women may actually want fewer children than the two so often seen as the desirable norm - indeed some are happy with none at all.
