Together with many other countries, Australia's population is ageing (see Australian Social Trends March 2009, 'Future population growth and ageing'). The size, growth and age structure of a country's population has profound implications for its social and economic development. Population growth and age structure is affected by births and deaths (natural increase or decrease) as well as by migration patterns. (Endnote 2)
In 2009, Australia's projected population of 21.9 million people accounts for 0.3% of the global population. In contrast, China and India's inhabitants account for 20% and 18%, respectively, of the world's population. The United States accounts for 5% of the world's population and the United Kingdom 1%.
PROJECTIONS OF THE WORLD POPULATION - 2009

Australia's population grew by an average of 1.5% per year between 1999 and 2009. This was slightly above the average growth rate across the world (1.2%) and in the US (1.2%), New Zealand (1.1%) and Canada (1.0%). Ireland had the highest population growth rate (an annual average of 1.9%) of any OECD country over this period. There was relatively slow growth in Japan (less than 0.1%), Italy (0.5%) and the United Kingdom (0.5%). Beyond the OECD, the Indian population grew by an average of 1.5% per year, while in China, where government policy mandates a limit of one child per couple in urban areas, the growth rate was 0.7%.
Australia's population is projected to grow at a faster rate than most other developed countries (1.1% per year), reaching 34 million or around 0.4% of the world's 9.1 billion inhabitants by 2050. The Japanese population, on the other hand, is projected to shrink by 0.5% per year over this time, while falls are also projected in the Russian Federation (0.5% per year), Germany (0.4%) and Italy (0.1%).
Most population growth is expected to occur in the less developed countries. For example, India's population is projected to grow by 35% between 2009 and 2050, seeing it overtake China as the world's most populous country.

Declining fertility and increased longevity will see many countries experience rapid population ageing in coming decades. The median age across all countries is expected to rise from 29 years in 2009 to 38 years by 2050. In Australia, the median age is expected to rise from 37 to 42 years over this time. Japan has the oldest age structure of any country in the world, with the median age expected to reach 55 years by 2050.
Population ageing is also expected in many of the least developed nations. These nations have relatively young populations as a result of high fertility and high mortality rates. For example, in Niger, which has the youngest age structure of any nation, the median age is expected to rise from 15 to 20 years between 2009 and 2050.
MEDIAN AGE OF POPULATION, MEDIAN PROJECTIONS

These trends will see an increase in the proportion of people in older age groups. In the more developed countries, the proportion of the population aged 60 years and over is projected to rise from 22% in 2010 to 33% in 2050. A similar trend is expected in less developed countries, with the proportion projected to more than double from 9% to 20%. In Australia, the proportion is projected to increase from 19% to 28% between 2009 and 2050. These trends are likely to pose serious economic challenges in many countries as the proportion of people of traditional working age falls, while demand for age pensions, health care and aged care services may increase.
HEALTH RISK FACTORS - SMOKING
According to the World Health Organisation, tobacco is the second highest cause of death in the world, responsible for about one in ten adult deaths, or five million deaths each year. (Endnote 3) Tobacco is also rated as the largest avoidable risk to health in OECD countries. (Endnote 4)
In 2007, Australia had one of the lowest smoking rates in the OECD, with around 17% of people aged 15 years and over smoking every day. Around the same period, Sweden had the lowest smoking rate in the OECD (15%), closely followed by the United States (15%). New Zealand, Canada, the United Kingdom and Italy all had rates below the OECD average of 24%, while Greece had the highest rate (40%).

Like most other OECD countries, in Australia men were more likely to smoke every day than women (18% compared with 15%). Across the OECD the smoking rate for men was 30% compared with 19% for women. In Korea, the rate of smoking among men was 10 times that for women (47% compared with 4.6%). Sweden was the only country in the OECD where women were more likely than men to smoke on a daily basis (17% of women compared with 12% of men).
There has been a marked fall in smoking rates across OECD countries in recent years. The decline in smoking rates in Australia (a fall of 40% for men and 44% for women between 1989 and 2007) was among the biggest in the OECD, along with Sweden where smoking rates fell by 52% for men and 36% for women. Other countries with large falls included the US, Canada, New Zealand and the UK.
While the smoking rate for men fell in all OECD countries between 1990 and 2007, the rate among women increased in a number of European countries. In Greece, for example, the proportion of women who smoked on a daily basis rose by 29% over this period. There were smaller rises among women in France (5%), Germany (4%) and Spain (less than 1%).

While crime levels have an impact on the rate of imprisonment, differences in prison rates across countries are also influenced by other factors associated with the nature of the criminal justice system such as sentencing policies. (Endnote 2)
In Australia in 2008 there were 129 adults in prison per 100,000 people. This was the 12th highest prison rate out of 30 OECD countries. Iceland had the lowest prison population rate of any OECD country (44), followed by Japan (63). The United States by far the highest prison population rate in the world in 2008 with 760 prisoners per 100,000 people.

Australia's prison population rate was slightly lower than the average across the OECD (139 prisoners per 100,000 people). However, this average is inflated by the US rate, which is more than three times as high as the next highest country, Poland (225). Without the US, the average prison population rate among the remaining 29 OECD countries in 2008 was 117 per 100,000 people, below the rate in Australia.
Research suggests that sentencing policies were a big factor in high prison rates in the United States. For example, property offenders and drug users are rarely imprisoned in European countries, while non-violent offenders make up more than half of the US prison population. However, violent offenders in the US spend five to ten times as long in prison as those in countries such as France. (Endnote 5)
Over the past 15 years prison rates have risen in most OECD countries. Between 1992 and 2008, the average prison population rate across OECD countries rose by 26%. In Australia the increase was slightly higher (31%). The greatest rise in proportional terms over this period occurred in Turkey (64%), while the United States had the largest increase in absolute terms (up 255 prisoners per 100,000 people, or 34%).
There were a few countries where the prison population rate fell between 1992 and 2008. In Iceland the rate more than halved, while Korea saw a fall of 34%. There were more modest falls in Canada (6%), Denmark (5%), Switzerland (4%) and Finland (2%).

Across the OECD, women make up only 5% of the prison population. Women account for 7% of the prison population in Australia, and 9% in the United States. Racial minorities are often over-represented among prison populations. For example, in the United States the prison rate among black men in 2007 (4,618 prisoners per 100,000) was six times that of white men (773), while the rate among Hispanic men (1,747) was more than twice that of white men. (Endnote 6) Similarly, in Australia in 2008, the prison rate among Indigenous men was 13 times that of non-Indigenous men. (Endnote 7)
PARTICIPATION IN FORMAL CHILDCARE
There is substantial research pointing to the beneficial effects of high quality early childhood care on children's outcomes later on in life, along with the benefits children get from positive social interaction with peers and non-related adults. Early childhood care also affects broader social and economic goals such as providing choice for parents in balancing their work and family commitments. In many OECD countries, maximising the proportion of mothers, in paid work is seen as critical to maintaining economic growth and ensuring the sustainability of social protection systems. (Endnote 8)
In 2006, an average of 28% of children between 0 and 2 years of age across OECD countries were enrolled in formal childcare. The Australian rate was similar, with 30% of 0-2 year olds attending formal child care in 2008. A considerable proportion of childcare in Australia is also provided privately or in an informal setting - in 2008, 30% of children under three were attending some sort of informal childcare. This was also the case in countries such as Mexico and the Czech Republic where less than 10% of children aged 0-2 years were enrolled in formal childcare.

Enrolment rates were much higher in Nordic countries such as Denmark (70%), Iceland (53%) and Sweden (44%), which have long histories of publicly funded childcare, and high levels of mothers participating in paid work. (Endnote 9)
The amount of time children spend in childcare can also affect children's developmental outcomes, as well as parents' ability to combine parenting with paid work. Across the OECD in 2006, children who attended formal childcare spent an average of 30 hours per week in care. There was considerable variation between countries, from 40 hours a week in Mexico and Portugal, to 17 hours a week in the Czech Republic and the Netherlands.
In Australia, children aged 0-2 attending formal childcare spent an average of 18 hours in care each week. This was towards the low end of OECD countries, along with the United Kingdom (18 hours) and New Zealand (20 hours). Longer time in childcare was relatively common in Nordic countries such as Iceland (36 hours), Finland (35 hours), and Denmark (34 hours), while the United States and Canada were slightly above the OECD average (31 and 32 hours per week, respectively).
