A population can be described in terms of the wellbeing of its members and the resources needed to sustain and enhance their wellbeing. Analysing changes in population size, composition and distribution can help in developing strategies to meet changing needs and to enhance people's wellbeing.
1.1 LIFE EXPECTANCY AT BIRTH, Selected years - Australia
EXPECTATION OF LIFE
Expectation of life at birth increases with age. For example, males born in 1970-72 had a life expectancy of 67.6 years. Males born in 1970-72 who were still alive in 2002-03, could now expect to live until 79.1 years.
The same is true for females. At birth in 1970-72 their life expectancy was 74.3 years but thirty years later, in 2002-03, their life expectancy had increased to 83.7
1.2 EXPECTATION OF LIFE IN YEARS, Selected ages - Queensland
LIFE EXPECTANCY AT 50
During the years 1881-90, life expectancy at 50 for females was 72.1 years and for males 69.7 years. The difference between male and female life expectancy widened after the 1940s until the mid 1980s. In 2000-02, life expectancy at 50 for females was 84.2 and for males 80.1.
1.3 LIFE EXPECTANCY AT 50 YEARS OF AGE, Selected years - Australia
ESTIMATED RESIDENT POPULATION
The size, composition or geographic distribution of a population is important because any changes present a large number of issues concerned with meeting economic and social needs.
Over the past 30 years (to June 2004), the estimated resident population of Queensland increased by 93% (1,873,700 persons). The number of persons aged 50 years and over increased by 146% (673,100).
In June 1974, 23% (459,700) of the population were 50 years and over. By June 2004, there were 1,132,800 persons aged 50 years and over accounting for 29% of the population.
Over the twenty years from June 1974 to June 1994, the proportions of males and females aged 50 years and over resident in Queensland increased for both sexes from 22% to 23% for males and from 24% to 25% for females. Over the last ten years, the proportion increased to 28% for males and 30% for females in June 2004.
1.4 ESTIMATED RESIDENT POPULATION, by age - Queensland
Population projections are based on a combination of assumptions on future levels in births, deaths and migration to arrive at the size, structure and distribution of Queensland's population into the future.
Projections show that the change in the age profile of the population, with a fall in proportion of younger people and growing proportion of older people, is expected to continue. Comparisons with other countries show that the ageing trend is a common experience among similarly developed countries. As the later stages of life have been associated with low income and high demands for health and community care, governments perceive a need to help maintain living standards.
The proportion of persons aged 50 years and over in Queensland is projected to continue to increase into the middle of this century. The most obvious trend is the steady decrease in proportion of persons aged 49 years or younger. In 2006, persons aged 0-49 years will account for 70% of the total population. By 2051, this age group is expected to account for 54% of the total population.
Over the same period, persons in the two oldest age groups (65-79 years and 80 years and over) will increase their representation in the total population. The strongest growth in the proportion of persons aged 65-79 years will occur between the year 2006, when they will account for 9%, and the year 2026, when they will account for 15% of the total population. Persons of this age group will account for 17% of the population in 2051.
The proportion of persons aged 80 years and over is expected to increase slowly between the years 2006 to 2021, then experience stronger growth from the year 2026 to 2051. This age group will account for 4% of the total population in 2021 and 10% in 2051.
