A new census for Wallis and Futuna shows an ageing of the population and a slowing birth rate.
The news agency, Agence France Presse, reports the French government survey shows the territory has a population of just under 15,000.
The survey says between 1996 and 2003, the population grew by an average of 0.8 per cent a year.
The census-takers report the territory has always seen an exodus of young people of working age.
The survey say 42 per cent of people between the ages of 15 and 60 declare themselves to be out of work.
Three-quarters of those says they've never worked and half say they aren't available to work.
