As far as the changes to Tableau go, here are some of the highlights:
+ Dashboards are now rendered specifically for iPads
+ Australian postcode data can now be plotted on maps automatically
+ Faster data processing and extraction, especially for test files
+ Ability to append additional data to extracts and data connections
+ View the input data as a whole via the left-hand side data window
The basic theory is that there's a severe undersupply of single men for single women, particularly in their 30's. At first glance, this would seem a bit odd given that there's a roughly 50/50 split of men and women at birth. So let's see if this is true ...
At the national level, there are actually more single men than women for ages 20 to 34. And for the 35 to 39 age group there's only around 10,000 more single women than single men. Overall, the man drought doesn't really exist for 30-somethings.
However, the man drought may just be a regional phenomenon.
The below maps highlight the ratio of women to men in between the ages of 30 and 39. Depending on the map and your gender preference, a redder shade indicates a less favourable ratio and a greener shade a more favourable ratio. The size of the location represents the total number of people aged 30 to 39.
Northern NSW appears to have the largest scarcity of single men aged 30-39 (ratio of 1.07), while there's an abundance of men in Regional SA (ratio of 0.85). Although these ratio's aren't particularly high, there's some evidence of the man drought in particular regions of Australia.
Now, here's the best bit. If we look at ratios of single women to single men aged 30 to 39 in particular postcodes, then there are some places in Australia with an obvious scarcity of men. The top 3 places (of notable size) are:
1. 2559, Blairmount, NSW - 2.4 women for every man
2. 4509, Mango Hill/North Lakes, QLD - 1.9
3. 6770, Halls Creek, WA - 1.8
It seems that there is a man drought, but it just depends on where you live. Similarly, there are places with a severe absence of single women in their 30s too. Here's the top 3:
1. 3008, Docklands, VIC - 0.4 women for every man
2. 5725, Roxby Downs/Olympic Dam, SA - 0.5
3. 4774, Moranbah, WA - 0.5
Note: There's a fair bit of data behind the dashboards so please be patient when zooming in to your location.
