Where were District home purchases in 2012?

According to data from the DC Office of Tax and Revenue, 5,372 single family homes or condo units were purchased at fair market value in the District of Columbia in 2012. The geographic distribution of these homes and their sales prices follows some generally unsurprising patterns.

Homes are expensive west of Rock Creek Park; Condo sales are concentrated in the core of the city and along certain major arterial roads; and the markets for this specific type of residential real estate lagged east of the Anacostia River and along Eastern Avenue.

These maps make a statement about where mobile homeowners and investors are choosing to live and risk their money in the District, which in turn reflects the perceived existing or potential quality of life in those neighborhoods. They also provide insight into the District's housing stock.

Neighborhoods with high concentrations of apartment buildings, whether 4 units or 400 units, will not have a dominant presence on the maps. Turnover rates and neighborhood density also influence these visualizations, as do many other factors that readers will surely suggest in the comments.

Some notes about the data: The above total includes 2,286 condominiums (horizontal or vertical) and 3,086 single family homes (attached, detached, or semi-detached). Some of these may have been sold more than once in the calendar year, but because the figures only reflect the most recent sale, those cases only count once.

Wow. I find it hard to think of a worse way to visualize these data. How am I supposed to draw any conclusions from a picture showing thousands of overlapping circles?

I agree with Gray. I can't tell how many overlapping circle I'm looking at in different areas. Why not just make each sale a dot and color code the dots for different sales price ranges? I think that would be more effective.

Please tell me this was made with a compass.

It looks like a planner decided to go all Jackson Pollock and threw grey splotches at a map.

I guess this one was a swing and a miss.
I was trying for something in between a heat map and a simple point plot and after staring at it long enough, this made sense to me. Oh well.

I don't hate the map. Maybe some kind of heat map would work better. I'm assuming size of the circle is related to sales price?

Chris...when in doubt, go with a color scale. White hot to blue cold.

by Michael on Feb 21, 2013 9:52 am • linkreport

Yeah, this might work if the dots were the same size, and you indicated price with color. If you got the opacity right...

If that doesn't work, this might just be better communicated with multiple maps: one showing density of sales, either with markers or as a heat map, and another heat map showing the price gradient.

Don't take it personally Chris. Better to swing and miss than not swing at all.

The message the map intends to convey is clear and obvious. And, I like the 'hand-drawn' quality of each circle.

In the words of 50-cent via kanye: don't switch yo style up, if they hate let 'em hate, and watch the money pile up
