Some census data for Carwoola

I have finally got around to exploring the Table Builder facility offered by ABS to allow people to access and analyse the results of the 2011 Census. IMHO this is an essential tool for anyone who wants to understand what is going on in this area. As a point of principle I will attempt in this post (and others of a similar nature which may follow) to present the data without explaining why it is so.  I will usually have an opinion about that but my opinion and $5 will get you a pie in most places.

On the basis of 'truth in advertising' I should point out that I worked for ABS for 30 years, the last 10 of which were as a manager in the Census area.  (I then did stints working on Census in Tanzania and for the UN Statistics Division.)

As a first step I decided to look at the industry of employment of people in the area.  Of course, to understand the industry data you first have to understand people's Labour Force status and to get one 's scone around that the age profile is important.  So we will start by looking at some information about the age and sex of people living in Carwoola.

Oops, sorry.  I forgot to mention the definition of Carwoola.  I have taken what ABS describes as the State Suburb definition of Carwoola.  This is best explained by a map from the Quick Stats facility.
For some uses (eg the Stoney Creek Gazette) the area covered includes at least a fair chunk of Hoskinstown and Primrose Valley but for this first foray I will stick to the area depicted.  We've got 4 years until the next lot of Census data comes out, so there is plenty of time to do some more posts later.  (I should also be comparing this stuff with NSW and Australia, but that will also come later.)

With all the charts below, click on them to get a bigger image.

Basic demographics.
The usual way this is described by statisticians is "people broken down by age and sex".  This is traditionally  accompanied by a snigger, as it shows that statisticians have a well developed and sophisticated sense of humour.

The first graph shows the number of people by sex and 10 year age groups.
This graph is quite interesting as it shows a bulge around the 40-60 age group and an astonishing sex-imbalance for the 20-29 age group.  The latter is worth a further chart.
The difference is clearly focussed on the 20-24 age group.  With only 354 people covered by the chart trying to go to single years is not really going to be helpful.  Any explanations of why young women move out of the area, but the blokes don't would be welcome!  (When I was domiciled in NYC for a couple of years the opposite was the case, with an astonishing imbalance towards young females.  This was thought to be the attraction of glamorous jobs in Madison Avenue etc - but I suspect many of them ended up closer to West 42nd St!)

Labour Force Status.
My impression, from the folk we mix with, is that a lot of people in the area are retired.  Possinbly because we are in that condition and thus tend to mix with other people of mature years (I use that designation as 'old farts' is a tad derogatory, and the term 'seniors' makes me want to chunder).  However, driving into Queanbeyan early in the morning shows clearly that there are lot of folk who have Meetings to go to.

This chart shows the numbers.
The next chart shows the number of people employed in each Industry at a high level of disaggregation.  (I have interfered with the official names to make them legible in this format.)

Clearly 'Public Administration' is the big ticket item in this area.  We can explore this a little further to look at a more detailed dissection.
Not surprisingly Australian Public Service is the biggest component with 74 employees.  Offering you another contribution towards some pastry (and meat if you are lucky) the presence of 35 Defence employees may relate to the location of the new facility near Bungendore.

I was intrigued by the relatively large number (22) of people in the final item "Public Order and Safety Services" so looked for more detail.  9 of these were police while the rest were described as 'Investigation and Security Services'.  We have no firies and no employees from the Maconochie Centre (aka the Canberra Jail).  What sort of persons are these Security persons?  From looking at the detail in the Classification of Industries for this Industry Class it appears that they are mainly going to be security guards.  I infer from this that the Industrial Division "Public Administration and Safety" includes private sector companies in the safety business.
