2016 Census – here comes the data!

Tuesday 27 of June 2017 is the official release date of 2016 Census data. The first batch of information contains a comprehensive list of demographic and socio-economic topics for areas down to local neighbourhood level.

The ABS Census of Population and Housing is conducted every five years and provides a comprehensive picture of Australia's people, how they live and where they reside. The information collected during the Census is used to distribute government funds and plan services for the community – including those relating to housing, transport, education, industry, hospitals and the environment.

Census data is also used by individuals and organisations in the public and private sectors to make informed decisions on policy and planning issues that impact the lives of all Australians. And of course, Census data is also a valuable source of statistics for research and data analysis in support of business activities as it provides comprehensive information on potential customers and markets.

MapDeck will be adding the 2016 Census data to its inventory progressively from the day of its official release, starting with free excerpts of statistics for Postal Areas.

All relevant Census 2016 related statistical geography is already available on MapDeck for immediate perusal. This includes, for example, Mesh Blocks, the smallest statistical geography units and building blocks for all other larger structures, like suburbs or postal and local government areas, etc.

A unique feature of Mesh Blocks is that each one is classified according to a dominant use of the area, like residential, parkland, education, commercial, etc. This makes it possible to use mesh blocks to create simple maps of land use, as the one below for the ACT.

Small area population estimates for Australia

The Australian Bureau of Statistics has recently updated its population estimates for Statistical Areas Level 2. This data set tracks 25 years of population changes in Australia back to 1991. The data is current as at 30 June 2016.

The Estimated Resident Population data set can be considered a prelude to the upcoming 2016 Census data release in late June 2017. It is still based on the 2011 edition of the Australian Statistical Geography Standard (ASGS2011) so, the figures for the SA2 areas will differ from the 2016 Census data, but ERP data is a good proxy of what to expect.

According to the ABS estimates, in 2016 there were 24,128,876 individuals residing in Australia, with the majority of people settled along the coast line. An interesting pattern of change over time is that, while the population in coastal areas continues to grow, there is long term depopulation occurring in the red centre - as depicted by blue polygons on the map below.

Population change 1991-2016 (blue - decline; orange and red - increase)

However, there is a notable positive change in the population of the Northern Australia, with some areas close to doubling its population in the last 25 years.

While population density in coastal areas has increased significantly over time, population growth is not uniformly distributed. Zooming in on capital cities allows pinpointing which areas have grown faster than the others.

For example, in the case of Sydney, the areas that stand out include Sydney City – Pyrmont – Ultimo, with a growth factor of around 9 (where 1 = no change and values below 1 indicate decline in population).

But the highest growth factor of 37.5 was recorded in Glenwood in the North West, followed by Parklea - Kellyville Ridge with 21.0 and Hoxton Park - Horningsea Park with growth factor of 12.7 over the last 25 years.

2016 Census Data is Coming!

On Tuesday 11 April 2017 the Australian Bureau of Statistics (ABS) will release a teaser, or snapshot if you like, of what attributes make up a ‘typical’ Australian in 2016. This information will only be available at the national and state/territory level. The first detailed 2016 Australian Census data will be officially released on Tuesday, 27 June 2017.

In preparation for this occasion, MapDeck.com is making its 2011 version of the Basic Community Profiles for Postal Areas dataset freely available. This free data release gives MapDeck.com users a chance to experience its unique capabilities of custom-map creation and personalised in-map analytics – and get ready for the avalanche of information that will be published in coming months!

It is a “big data set about small areas” - in total there are 7,942 individual data items, spread across 66 tables, which can all be used for mapping. There is also a companion data set in Excel format which helps explain the structure of the data and what is specifically available in individual tables.

Postal Area Boundaries 2011 and 2016 are already available for free perusal on the MapDeck.com platform and both versions can be conveniently compared on the Australian Postcodes map.

Below you will find links to several public maps - they are published as examples of what can be created with MapDeck’s Thematic Mapper app:

Population by Postal Areas, Australia 2011
Dwellings by Postal Areas, Australia 2011
Selected Averages by Postal Areas, Australia 2011

Dissecting Australian Property Investors

Is Sydney the epicentre of property speculation in Australia? ATO data provides a surprising answer…

A lot has been said about Sydney property investors in recent years, mostly in derogatory terms. Commentators usually criticise their financial irresponsibility, or even sheer madness, for “piling into the residential property market with excessive leverage” - something which is said to inevitably end badly for each and every one of them. But are these opinions justified?

The Australian Taxation Office (ATO) data summary of 2013-14 individual tax returns for postcodes, the latest available, paints a surprisingly different picture.

In particular, it is true that property investment is quite popular amongst Sydneysiders. This is clearly illustrated on the following map - purple shaded polygons mark postcodes with the above average proportions of property investors amongst the residents, comparing to figures for Australia as the whole.

However, the big surprise revealed in the ATO data is that a significant proportion of Sydney-based property investors are actually netting hard cash from renting out residential properties. That is, their residential property portfolios are not negatively geared at all!

The following map points out postcodes in the Greater Sydney area with a positive average net rental income per investor. There are quite a few of them. So, it turns out, Sydney-based property investors are not leveraged to the hilt en masse as is commonly assumed.

There are actually only a handful of postcodes in Greater Sydney with residents who very aggressively gear their investment property portfolios. That is, postcodes which have above average proportions of property investors, and where residents report rental losses at above the national average level. These are marked on the following map as areas with red background.

And of those, there are only six postcodes where 6,268 property investors (out of the total of 2,672,004 taxpayers counted in the Greater Sydney area) potentially fit the common stereotype of a property speculator. That is, property investors residing in these postcodes invest in rental properties in above average proportions comparing to the national average and have no or very limited other investments (i.e. are categorised as “Property Centric” investors). AND, at the same time, they are also highly leveraged (i.e. report above average rental losses to the ATO).

These are postcodes 2745, 2768, 2769, 2171, 2173 and 2231 - marked on the map as red polygons with black horizontal stripes.

Concluding, it is very unlikely that things have changed dramatically in the last two and a half years. So claims of irresponsible, mass scale residential property speculation by Sydneysiders are rather exaggerated. In fact, it appears that quite the opposite is true.

Only aggregated data is available for analysis, nevertheless, it suggests that large proportions of Sydney-based taxpayers are playing very safely with residential property investments and are generally diversified into several investment classes, including shares, cash and equivalent.

A full set of ATO statistics for postcodes, with extended investor profile information, has been published by MapDeck.com and is accessible online.
