A spectacular decline in infuenza mortality: the role of
Every autumn sees the start of the annual flu vaccination campaign,
with particular focus on older adults, high-risk individuals or
those in regular contact with persons at risk. But do we know how
many people die of infuenza each year? And does vaccination save
lives? France Meslé looks into these questions, examining infuenza
mortality trends in France and in industrialized countries over
Human fecundity: situation and outlook
Fecundity may have decreased slightly in some industrial countries
over recent decades, and concerns have been expressed about potential
population decline. Henri Leridon shows that this fear is largely
unfounded, and takes a closer look at the question of human fecundity.
The number and proportion of immigrants in the population:
The proportion of immigrants varies considerably from one country
to another. In some countries it exceeds half the population while
in others it is below 0.1%. Where are immigrants most numerous?
Where do they come from? More generally, how are they distributed
across the world?
Will life expectancy increase indefnitely by three months
Jacques Vallin and France Meslé
Life expectancy is still increasing in industrialized countries
and has extended well beyond the biological limits announced just
a few decades ago. Examining the record levels actually observed
over time, Jacques Vallin and France Meslé present an overview
of the successive stages of progress in human health and the factors
behind this progress, and discuss the prospects for an ever longer
length of life.
Is there a childbearing season?
Arnaud Régnier-Loilier and Jean-Marc Rohrbasser
Births are not evenly distributed over the seasons, and tend to
be more numerous at certain times of year. These variations have
always existed, but their pattern has changed over time. Arnaud
Régnier-Loilier and Jean-Marc Rohrbasser explain the seasonality
of births in France and the reasons behind the changes observed
over the last four centuries.
Tracking the lives of 20,000 children Launch of the Elfe
child cohort study
Marie-Aline Charles , Henri Leridon, Patricia Dargent, Bertrand
Geay and the Elfe team
Twenty thousand children born in France in 2011 will be followed
from birth to adulthood to understand how the environment, their
family life and their living conditions affect their health and
development. The lead scientists of this study co-ordinated by INED
and INSERM – the frst of its kind ever conducted in France – explain
the reasons behind its launch, the method used to recruit and follow
the cohort of children, and the results they expect to achieve.
Two children per woman in France in 2010: Is French fertility
immune to economic crisis?
Contrary to expectation, the number of births continued to increase
in France in 2010, despite the economic crisis. Instead of lowering
fertility, has increased unemployment actually produced the opposite
effect? Are jobless women taking advantage of their situation to
have a child? To shed light on the question, Gilles Pison analyses
the relationship between economic climate and fertility in France
and in other developed countries, notably during periods of recession.
