It is not work in general that is causing a decline in women giving birth at a young age. It is specifically temporary jobs that are responsible. In Australia part-time and casual employment has boomed over the last decade as employers see it as a way to keep costs down. Many work extra hours for no money at all, afraid of losing their jobs.
Women working full time can afford to pay for child care, or at least for critical periods when they are working. Such career women are having children before they reach the age of 35 years. There is a myth out there that it is these career women who are starting families at an older age. Oddly the effects of not working full time changes the behavior of women in the high socieconomic group as well. They may be able to afford childcare from a financial "nest egg", but it is the state of mind about not working enough and not having sufficient income for a family.
Financial security in regard to income is essential for women to even consider having children. Careers are not that important to women. This goes against all of the prevailing stereotypes. The number of years spent in part-time work had a strong impact. A year of part-time employment reduced the probability of having a baby by 35 years by 8 per cent. Five years in such work increased the rate to more than a third.
Another myth is that university graduates go straight into full-time employment. Over 60 per cent of these began working in a job with reduced hours. Therefore, high and low-skilled women suffered the same job market problem.
All economies are moving to less-secure employment to reduce production costs. This means that as the decades go by the world population will fall, confounding all predictions. Furthermore, the population in most countries will have a larger proportion of elderly people. Some of these will have to work to survive. Providing old age pensions will become too costly.
