Welcome to the August 2004 edition of Age Matters. While Maryann Wood is undertaking other duties and having a well earned break, over the next couple of months, I will be managing the National Ageing Statistics Unit. We also welcome Tara Pritchard as Director of the Population Statistics Branch in the Queensland.
Work continues on our Mature Age Profiles. The profiles, which will be released from October, 2004, analyse various components of mature age persons (those aged 45-64 years) including demographics, cultural diversity, labour force characteristics, health, housing, living arrangements and community life.
The profile analysing the mature age characteristics of the labour force will be presented at the Australian Population Association Conference in Canberra in September, 2004. At the conference, we will also be presenting a paper on the use of information technology by older people.
In this issue of Age Matters you will find the following main article of interest:
- Human Capital - an important concept in modern economics and in economic policy discourse. The ABS has produced experimental measures of the stock of human capital for Australia by measuring the stock of human capital as the discounted present value of expected lifetime labour market income. The estimates show that there has been a significant increase in the stock of human capital in Australia over a 20 year period, characterised by sharply rising shares of total human capital attributable to more educated workers. This article will show results from this study, highlighting the impact of changes in the population's age structure on human capital stocks over the past twenty years.
We also provide links to 'Seachange - new coastal residents' an article from Australian Social Trends (ABS cat. no. 4102.0) which looks at who is moving to the coast and from where they have moved.
I look forward to being a part of the National Ageing Statistics Unit over the next couple of months. If you have any suggestions for the newsletter or queries regarding statistics on ageing, please do not hesitate to contact me.

The following findings are summarised from an ABS working paper Measuring the Stock of Human Capital ABS cat. no. 1351.0.55.001), released in May 2004.
In the Australian System of National Accounts measures of capital stock are currently confined to physical capital. Although human capital is an important concept in modern economics and in economic policy discourse, direct measures of human capital stocks are available for very few countries. In order to fill this gap, the ABS has recently produced experimental measures of the stock of human capital for Australia.
Human capital can be simply viewed as productive capacity embodied in working-age individuals. The dynamics of this capacity critically depends on investment in education and training. Human capital growth is a key driver for productivity growth and in sustaining higher standards of living for Australians. Given that the Australian population is ageing, there are significant implications for Government expenditures on health and social welfare payments: human capital is particularly pertinent to policy makers and economic/social analysts.
This article will show some results from this study, highlighting the impact of changes in the population's age structure on human capital stocks over the past twenty years.
The method chosen to measure the stock of human capital is the lifetime labour income method as used by two American national account economists Dale Jorgenson and Barbara Fraumeni. This measures someone's human capital as the total income they could generate in the labour market over their lifetime. In order to use this method, inferences about future income streams are made using cross-sectional information on current earnings. These projections are made separately according to people's sex, age and educational attainment. The information on differences in income streams from alternative educational attainment could be useful for analysing returns to investment in education.
The data used for this analysis is from the Australian Census of Population and Housing in 1981, 1986, 1991, 1996 and 2001. Age-earnings profiles are constructed for four categories of educational attainment for both men and women over this twenty year period. Based on these age-earnings profiles, per capita measures of lifetime labour market incomes are derived for each age/sex/education cohort using appropriate growth and discount rates, and they are then applied to the number of people in the corresponding group. We then aggregate across all groups to estimate the human capital stock for Australia, which is presented in the following table.
TABLE 1: MEASURES OF HUMAN CAPITAL STOCK IN AUSTRALIA (BILLIONS OF CURRENT DOLLARS)
The two fastest growing categories for human capital stock are women with higher and bachelor degrees. The fastest category for both men and women was the higher degree, however the stock has grown faster for women than men over the twenty year period. The growth in human capital stock in the 1980's was mainly due to an increase in the total population rather than an increased rate of growth in a particular area. The growth in the human capital stock in the 1990's however, was driven by an increased rate of growth in a specific area, higher and bachelor degree holders. The growth rate for skilled labour and unqualified people has been slowing over the past twenty years, where both men and women have slowed at the same rate. This suggests that while the Australian population has been ageing, we are also becoming more educated.
The average age of educational attainment by Australians increased between 1981 and 2001. Table 2 illustrates changes in average age of men and women holding different levels of educational attainment.
TABLE 2: AVERAGE AGES BY EDUCATIONAL ATTAINMENT, YEARS
Table 3 shows the contribution to growth in human capital stock from people with different levels of educational attainment. Growth in human capital stock has been driven by increases in the human capital embodied in the skilled labour and bachelor degree groups.
As people age, their human capital changes. All other things being equal, someone's remaining lifetime labour income will tend to decrease (because their time left in the labour force has shortened). However, as people spend longer in the work force they gain skills and experience, which increases their productive capacity and, therefore, their income. The rate at which they gain skills and experience can change over time. Table 3 suggests that any reduction in human capital from a "reduction in working life" effect, has been more than outweighed by the "increasing skills and experience" effect combined with an increase in the number of people classed as 'skilled labour' or with higher educational attainment.
TABLE 3: DECOMPOSITION ANALYSIS OF GROWTH IN REAL HUMAN CAPITAL STOCK (%)
Australian human capital has increased significantly over the past 20 years, despite an ageing population. The more educated stock of human capital has increased most rapidly, especially among women, while the average ages of people with tertiary qualifications has also increased, in particular for higher degree and bachelor degree holders. Any reduction in human capital from an ageing work force effect, has been offset by increases in the quality of human capital in the workforce.
In the future, the ABS hopes to use these estimates of human capital stock alongside physical capital to establish a more complete understanding of national 'capital'.

SEACHANGE - NEW COASTAL RESIDENTS
The beach holds an iconic status in our culture. Coastal regions have long been a favourite place for Australians to take their holidays and relax. More recently, researchers have identified an increasing tendency for people to live near the coast.
For an analysis of who in the population is moving to the coastal regions, refer to the ABS publication Australian Social Trends 2004 (ABS cat. no. 4102.0) feature article Seachange - new coastal residents
The analysis is based on the 2001 Census of Population and Housing and examines the characteristics of people who moved to a high growth coastal region during the year before the 2001 census.

DID YOU KNOW?
In June 2003,
- the number of older people (aged 65 years and over) in Western Australia rose by 3.1% (in the 12 months to June 2003). In this age group, the number of females exceeded the number of males, with 82.0 males for every 100 females.
- the largest proportions of persons aged 65 years and over were in the statistical divisions of the South West (13.8%) and Lower Great Southern (14.0%). In contrast, the Pilbara and the Kimberley had only 2.4% and 4.4% of their respective populations in this age group.
- people aged 85 years and over accounted for 1.3% of the total Western Australia population and 11% of those aged 65 years and over, in June 2003.
- Only 4 statistical local areas had more than 3% of their population aged 85 years and over - Claremont (3.9%), Victoria Park (3.7%), Stirling - South Eastern (3.6%) and Nedlands (3.4%). Outside the metropolitan area, the statistical local area of Albany - Central had the highest proportion of their population aged 85 years and over (2.7%).

Details of job mobility, job tenure, number of employers or businesses during the year and reason for ceasing last job or changing locality are presented. Occupation, industry and duration of current and last job are also available. Estimates can be cross-classified by labour force demographics such as state, sex, age, marital status and country of birth.
Perspectives on Regional Australia: Women's Employment in Urban, Rural and Regional Australia, 2001 Census (ABS cat. no. 1380.0.55.001) was released on 17 August 2004. This publication is the first of a series of reports analysing a range of topics with a particular focus on Regional Australia. In this issue data from the 2001 Census of Population and Housing has been used to present some perspectives on the characteristics of women in employment in urban, rural and regional Australia.
This paper provides an insight into the different employment conditions experienced by women in regional Australia by examining characteristics such as age, employment status, income, qualifications and industry of employment. The data is presented using the geographic classification "Section of State" which enables comparisons in employment patterns across major urban cities, medium townships, small townships and rural areas of Australia.
