The elderly population, especially women aged 80 and over, is growing due to increased life expectancy. Projections for this demographic show regional variations and potential underestimation for women.

Area of Science:

  • Demography
  • Gerontology
  • Public Health

Context:

  • Utilizes Statistics Norway data to analyze demographic shifts in the population aged 80 and over until 2020.
  • Observes a significant rise in the proportion of elderly women (80+) from 2% in 1970 to nearly 5% in 1993.
  • Notes parallel trends of increased life expectancy and reduced cardiovascular mortality in both sexes, contrasted by rising cancer mortality in men.

Purpose:

  • To examine the demographic development of the very old population up to 2020.
  • To identify trends in life expectancy and mortality rates among the elderly.
  • To assess the accuracy of population predictions and regional demographic variations.

Summary:

  • The study highlights a substantial increase in the elderly female population (80+), linked to enhanced life expectancy and declining cardiovascular mortality.

  • While men also experienced reduced cardiovascular mortality, this was offset by a nearly 50% increase in age-specific cancer mortality.
  • Population predictions appear ambiguous, particularly underestimating the growth of elderly women, and regional differences in demographic development are noted but not clearly linked to mortality.

    • Impact:

    • Provides insights into the aging population trends and their contributing factors.
    • Identifies potential inaccuracies in demographic forecasting for the elderly.
    • Highlights the importance of considering sex-specific mortality trends in demographic analysis.
    • Underscores significant regional disparities in the development of the population aged 80 and over.
