Using data from Wave 1 of the Household Income and Labour Dynamics in Australia (HILDA) survey, this paper analyses the extent to which childlessness among Australian women aged 40–54 years varies according to the size and type of family in which they were brought up, and the level and type of schooling they had. Multilevel logistic analysis shows that having been educated in a non-government school, having stayed at school to year 12, having a small number of siblings, at age 14 having a father who was either dead or absent, at age 14 having a father who was employed in a professional occupation, or being a migrant from North or West Europe, North America, East Asia or South-East Asia, all are significantly associated with higher rates of childlessness among women in the 40–54 years age range. The effects of these early lifecourse variables on marital and socioeconomic status in later life, and hence on childlessness, are also considered. The implications of the findings for fertility trends and for Australia’s public debate are discussed.
This paper examines the relationships between satisfaction with life in general, particular domains of life, the partner, and parental relationships with existing children, and subsequent fertility. The data are from 2,948 women and 2,622 men aged 15 to 44 years, from a longitudinal survey of the household population in Australia. For both sexes, a strong positive relationship between prior satisfaction with life and fertility two years later is found. Men's satisfaction with their partner and with their partner's relationship with existing children are positively related to fertility. Fertility is also related to age, parity, marital status, education, employment and birthplace.
Using data from the 1996 and 2001 censuses of Australia, this study provides a detailed description of the diverse patterns of occupational concentration and mobility of selected Asian immigrant groups. The study shows that Asian-Australians include not only groups which remain relatively concentrated in “low-end” occupations, but also many others which are more likely than the Australia-born to be in “high-end” professional occupations, and that almost all the selected groups experienced some degree of upwards occupational mobility between 1996 and 2001. However, after controlling for a range of demographic and human capital characteristics, the participation of most groups in the managerial and professional occupations is shown to be below that for the Australia-born. Hence, the high occupational status of most Asian groups does not mean they are advantaged.
BackgroundMany populations have been exposed to environmental lead from paint, petrol, and mining and smelting operations. Lead is toxic to humans and there is emerging evidence linking childhood exposure with later life antisocial behaviors, including delinquency and crime. This study tested the hypothesis that childhood lead exposure in select Australian populations is related to subsequent aggressive criminal behaviors.MethodsWe conducted regression analyses at suburb, state and national levels using multiple analytic methods and data sources. At the suburb-level, we examined assault rates as a function of air lead concentrations 15–24 years earlier, reflecting the ubiquitous age-related peak in criminal activity. Mixed model analyses were conducted with and without socio-demographic covariates. The incidence of fraud was compared for discriminant validity. State and national analyses were conducted for convergent validity, utilizing deaths by assault as a function of petrol lead emissions.ResultsSuburb-level mixed model analyses showed air lead concentrations accounted for 29.8 % of the variance in assault rates 21 years later, after adjusting for socio-demographic covariates. State level analyses produced comparable results. Lead petrol emissions in the two most populous states accounted for 34.6 and 32.6 % of the variance in death by assault rates 18 years later.ConclusionsThe strong positive relationship between childhood lead exposure and subsequent rates of aggressive crime has important implications for public health globally. Measures need to be taken to ameliorate exposure to lead and other environmental contaminants with known neurodevelopmental consequences.
