As those who’ve checked out/had to put up with my many word clouds on various different topics from Wicklow genealogy to Barack Obama will testify, I’m always looking for new ways to present data and information. For those with similar interests, a useful tool in that regard is Manyeyes, a free data visualization service offered by IBM. First thing you might do when you click through is have a wander around some of its featured visualizations, such as the OECD economic outlook or the World Cup Finals.
You needn’t stop there, though, as once you’ve registered, you can upload datasets yourself and visualize them. What’s particularly cool, in my opinion, is the ability to do maps with subnational data points, e.g. for the USA, China and, somewhat surprisingly until you remember IBM’s presence in the country, Ireland.
So I plugged in some county-level statistics from the Daft.ie database, in particular the year-on-year % change in asking prices by county from the first quarter of 2007 to the third quarter of 2008. The results are available for all to see on Manyeyes – I haven’t been able to put a live visualization up here, but you can get a sneak preview below and indeed the whole shebang just by clicking on the picture.
What, even clicking on the link is too much hassle? OK, here’s the lazyman’s version:
The easiest way to get the overview of the story – but with the minimum detail and surprise factor – is to go straight from 2007-q1 to 2008-q3. As you can see the map goes from totally brown to totally blue! But that naturally is hiding a lot of detail… So here are some other highlights on regional trends in Ireland’s property market:
- Sligo is a constant underperformer – having enjoyed some of the smallest increases in the first half of 2007, it’s now suffering from some of the largest falls in 2008
- Aside from Sligo, West Leinster was the first region in the country to suffer from falling house prices, in year on year terms, with Longford and Laois falling in year-on-year terms by (and we can pretty much throw in Westmeath there too, where prices were no higher than a year previously, in the same quarter)
- In late 2007, asking prices in south-east Leinster (e.g. Carlow, Kilkenny) and neighbouring Munster counties (Tipperary, Waterford) were still rising in year-on-year terms.
- Limerick was the last bastion of rising house prices. It’s the only county not to have registered two consecutive quarters of year-on-year falls in house prices… yet!
- Have a look at 2007-q4… poor old Donegal just doesn’t get it! Even in early 2008, it was still at it. In Q3 2008, though, with prices down over 11% compared to a year earlier, it’s landing with a bang.
There are just some initial observations on the figures – overall, Manyeyes is a pretty useful tool, I’d have to say. I’d be interested in hearing anyone else’s observations on regional differences in price trends. What have I missed? Or indeed, what should I be heat-mapping?
