Les figures publié l’office des Statistiques de Nouvelle-Zélande indiquent l’évidence du vieillissement de la population de ce pays.
Pendant la décennie passée le nombre de personnes âgées de plus 90 ans a augmenté de deux-tiers, alors que la catégorie d’âge 80-89 ans se développait d’un tiers.
Les figures indiquent également une petite baisse dans la croissance de population depuis 2003 qui est dûe à une réduction des migrations permanentes et à long terme.
The resident population of New Zealand was 4,084,200 at 31 December 2004, according to the latest population estimates released by Statistics New Zealand. The population aged under 15 years decreased by 1,800 (0.2 percent), from 884,300 at 31 December 2003 to 882,600 at 31 December 2004.
In the December 2004 year, the population growth was estimated to be 44,800 (1.1 percent), compared with 63,500 (1.6 percent) in the December 2003 year. The population growth in the December 2004 year is marginally higher than the average annual increase of 43,600 (1.1 percent) for the December years from 1994 to 2004.
The lower population growth during the December 2004 year was due to a fall in permanent and long-term migration. Permanent and long-term arrivals exceeded departures by 15,100 (34 percent of the population growth) in the December 2004 year, whereas in the December 2003 year the net migration gain was 34,900 (55 percent of the population growth).

The population aged 65 years and over (65+) grew by 72,600 (17.3 percent) over the last decade, to reach 491,600 at 31 December 2004. The largest population growth in this category over the last decade was in the 90 years and over age group, at 66.2 percent. The 80–89 year and 65–79 year age groups grew by 35.8 and 11.2 percent, respectively, during the same period. The 65+ age group accounted for 12.0 percent of the population at 31 December 2004.
The working-age population (15–64 years), which accounted for 66.4 percent of the population in the December 2004 year, was estimated to be 2,710,100 at 31 December 2004. This is an increase of 322,200 (13.5 percent) compared with the December 1994 year. The population aged under 15 years grew by 41,200 (4.9 percent) during the same decade, to reach 882,600 at 31 December 2004.
