Population aged 70 and older in Australia - Data and Analysis (1971-2033)

IBISWorld forecasts the population aged 70 and older to increase by 3.5% during 2025-26, to reach 3,578,002 people. The strong growth in this demographic is primarily due to rising life expectancy in Australia. Improvements in healthcare and medical technology are causing people to live longer, contributing to growth in the number of people aged 70 and over. Concurrently, baby boomers have continued to reach 70 years of age, further driving up the population of people aged over 70 years old. The demographic's growth is significantly higher than the overall population growth, a trend which is indicative of Australia's ageing population.Over the past five years, the population aged 70 and over has consistently grown at a faster rate than Australia's total population. Rising life expectancy, due to medical and healthcare developments, has underpinned growth in this demographic, and more people are living to 70 years of age and beyond than ever before. A record number of people are also reaching 100 years of age, further driving growth in this demographic's population.The first members of the baby boomer generation entered this age group in 2016-17, with many more reaching 70 years old over the past five years. The baby boomer generation includes people that were born between 1946-47 and 1964-65, when birth rates increased dramatically due to post-war government policies that actively promoted population growth. The proportion of people in this age group relative to the total population is expected to increase from 5.3% in 1970-71 to 12.8% in 2025-26. Overall, IBISWorld forecasts the population aged 70 and older to grow at a compound annual rate of 3.4% over the five years through 2025-26.
