The document discusses trends in Australia's aging population from 1901 to 2061. Some key points are: - The percentage of the population aged 65 and over is projected to increase from 14% in 2013 to 31% in 2061. - Labor force participation rates of those aged 55 and over have been increasing steadily since the late 1970s. - An aging population can provide economic and social benefits such as a decreased percentage of life spent childrearing, more opportunity for work and volunteering, and potentially less crime and violence.
