Twenty years of urban growth and change

Australia is said to be one of the most urbanised countries in the world. The 2021 Census showed that 90% of the population lived in urban areas with more than 1,000 people. This blog looks at the growth of urban areas in Australia over the period 2003-23. What are Australia's largest urban areas? Which ones have grown the most? Read on to found out.

The Nepalese population in Australia has doubled since 2016

In late June the ABS released the first batch of 2021 Census data. The Census provides critical information on the socio-economic characteristics of the population, which underpins the evidence base for service planning. This is the first in a series of a number of blogs highlighting important and interesting changes to the Australian demographic landscape. This blog looks at the Nepalese population in Australia.

Population distribution in Australia

One of the more interesting demographic trends in the last two years has been the increased movement of people out of large cities into regional and rural areas. These so-called "flee changers" have local impacts with regard the demand for services and infrastructure, there is still some question as to whether this represents a long term shift in the distribution of the Australian population. This blog looks at the distribution of the Australian population over the last 100 years, concentrating on the state capital/rest of state split.

Building approval trends in NSW

Much has been written in the last 18 months about the increasing population in regional Australia. The driver of this has been attributed to COVID-19 influenced migration (so called "flee changers"). This is despite the fact that the number of people moving out of Sydney and Melbourne has been increasing for some years, ie it predates the pandemic. This blog looks at residential building approvals data, concentrating on NSW, and its relationship to population change in regional areas. 

What's happened to Australia's young adults?

It goes without saying that the impacts of COVID on population change have been profound. Not only has Australia recorded a net loss of overseas migrants but there have been changes in the age structure as a result. In 2019-20, the population of young adults in Australia declined. This blog looks at the scale of this trend and where the impact has been felt more strongly.

How language data can inform public health policy - the Sydney version

The current outbreak of COVID-19 cases in Sydney has some close parallels to the second wave that hit Melbourne last year. Not only is the Sydney outbreak proving difficult to control, but it appears that public health messages are not reaching multicultural communities (CALD). This is particularly true where English proficiency is poor. This blog is essentially a Sydney version of one that I wrote last year about Melbourne. It looks at the main languages spoken in Sydney, highlighting those with poor English proficiency, and their spatial distribution in the metropolitan area.

Are people leaving Sydney and Melbourne in droves?

It seems that not a week goes by without reading an article that highlights the sea/tree change phenomenon. The tone of these articles suggests that people are leaving Sydney and Melbourne in such numbers that the streets are devoid of people and life - save the obligatory tumbleweed. Recent ABS data releases on internal migration have meant that more timely analysis of the ebbs and flows of people around the country is possible. So what exactly is happening? Let a demographer, not a property analyst, put it all into context.

Life expectancy in Australia

Australia is in the fortunate position of having one of the highest life expectancies in the world. A child born in 2019 can expect to live to 82.9 years. Life expectancy is a function of many factors including mortality rates and the quality of the health care system. Although most people are familiar with the concept of life expectancy, many are not aware that there are differences across the country. This blog looks at life expectancy trends in Australia from a spatial and temporal perspective.

Would Australia's population grow without overseas migration?

I've written a few blogs previously that describe the impacts of COVID-19 and border closures on population growth and change. The situation continues to evolve and the impacts differ by location. By far the most impactful measure implemented is the closure of the international border. This has effectively cut off the major source of population growth - net overseas migration (NOM). In 2018-19, NOM accounted for 62% of population growth in Australia. So yes - Australia's population will grow without overseas migration, but there are significant differences between the state capitals and regional areas. This blog takes a scenario approach and looks at the impact on population change that occurred in 2018-19 had there been no overseas migration.

Where do international students live?

In May 2020 I published a blog that discussed the impact of COVID-19 on population growth and change in Australia. I argued that the biggest impact would be on the volume of net overseas migration (NOM), but the scale of the impact would depend on how long travel restrictions and the border closure were enforced. Two months later this still rings true. The recent spike in COVID-19 cases in Victoria just shows how precarious the situation is, with restrictions likely to remain in place for some time. This blog progresses the themes I presented in the previous blog, but looks specifically at international students and their contribution to population growth and change in Sydney and Melbourne. 

Vacant dwellings in NSW - trends and prospects

Most people are familiar with the idea of the Census as a population count, but a lot of additional data on dwellings and households are also collected.  Similar to population variables, housing data is also available for small geographic areas.  This enables users to see the spatial patterns and characteristics across our cities and regions.  This blog looks at vacant dwellings in NSW, with particular reference to spatial patterns and possible future trends.

Melbourne versus Sydney - a long standing rivalry

The rivalry between Melbourne and Sydney has a long history.  Everything from the weather to the football is keenly debated.  But one thing remains a fact - Sydney is Australia's largest city, with a 2018 population of 5.23 million.  But has it always been this way, and what of the future?  Read on the find out more.

Are inner city areas attracting older residents?

If I had a dollar for every time I was told that older people are downsizing in droves and leaving the suburbs for the inner city, I'd be a much richer person.  This perception has persisted despite the evidence to the contrary.  Every so often an article will appear in a newspaper that perpetuates the myth.  The most recent example appeared in the SMH and used a case study approach to illustrate how the inner suburbs are changing through in-migration of older persons, and how this might continue into the future.  While there's little doubt that the individuals in these articles did make such a move, but is really it a trend?  Let's have a look at the evidence, using inner Sydney as a case study.

The young and the old - how age structures differ across NSW

Recently I published a blog that looked at the importance of considering age alongside other social variables in order to give it more context.  This blog will continue the age theme, but look at examples of different age structures across NSW.  The data is sourced from the ABS release Regional Population by age and sex (ABS Cat. no. 3235.0) and as such uses the 2017 ERP (Estimated Resident Population - the official figure) rather than the Census figure.

Australia's regional cities - which ones are growing?

High levels of population growth, particularly through overseas migration, have well and truly put the spotlight on population issues.  But population growth is uneven, and many of the problems are seen through the lens of people stuck in traffic jams in Sydney and Melbourne.  The new Australian Prime Minister, Scott Morrison, has flagged the potential for policies whereby new migrants are required to live in regional areas.  There have also been calls for greater incentives to encourage people and jobs to decentralise, especially to our regional cities.  This blog looks at recent growth trends in Australia's regional cities and considers the issue of whether or not they can alleviate growth pressures in our major cities by increasing their own population growth.

Australian migrants - just who are they?

There's no disputing that the ABS releases a lot of demographic data.  The quarterly publication, Australian Demographic Statistics, provides regular headline numbers.  These are the ones found splashed across the front page of newspapers and fuelling debate about an appropriate level of population growth in Australia.  But it's the annual releases of data which provide more detailed insights into how the population is growing and changing.  Last week the ABS released Migration Australia (Cat. no. 3412.0).  Given that migration is the topic de jour, it's worth looking at what this data tells us.
