There’s always a story in the numbers…creating FUD from that story is the media’s job; making sense from it is mine

If there’s one thing I learned from my tenure in consulting (apart from the names of the cabin crew on the mid-Sunday afternoon American Airlines flight from SFO to JFK…) it’s that the numbers always tell a story.
Remember this neat little chart from our little “Frolick with the data” yesterday, provided by those whiz-bang numbers folks at Altos Research?
Statistically-challenged reporters (is there another kind?) look at this and concoct two dramatic headlines, depending on whether you look before or after July 2006: “Prices drop dramatically!” or “Prices increase dramatically!”
Both headlines are, technically, true — in the same sense that your favorite team’s one-game loss could be a “losing streak” and a one-game win could be a “winning streak.”
What’s behind these numbers?
Quite simple: The variation in prices this year in Palo Alto is due nearly entirely to the difference in home size. Put another way, home prices fell between January and July because smaller homes were selling, and home prices rose between July and October because larger homes were selling. Boring facts like that don’t sell newspapers, however, which is why you’d never get an explanation like that in the San Jose Mercury News.
Check this out:
From January to July, median prices dropped 17%, most steeply between January and May, and less steeply from May through July. From July till now, prices have increased 13%.

Best blog article I have read in weeks. Make sure you submit it to the Carnival.

Thanks. Good analysis.
However - it does beg a follow-on question. What can we learn from the down-tick and later up-tick in sizes of houses being sold ? Is there rhyme-and-reason underling the observed trend (which you very accurately analyzed) ?
I think ’sizes=total price’ (i.e. it isn’t that people are all of a sudden interested in larger or smaller houses at certain times of the year).
What is interesting to ask is: is this a pattern change in demand or in supply (i.e. is the reason smaller houses were selling for a while because larger ones were not on the market, or because they were on the market but people were not buying ?).
Also - what would be interesting is to overlay it with a possible ‘culprit’: interest rates.
Is the swing in ‘house sizes’ (again in my mind possibly an ‘alter-ego’ of total-purchase-price) correlated to changes in interest rates ?

[...] A friend of mine named Eilam, also a numbers sort of guy, made an interesting comment about my previous post in which I dissected the year-to-date real estate numbers for Palo Alto, CA. He challenged me to look still deeper into the numbers and try to figure out whether I had the cause-and-effect in the right order. [...]

I’m simply shocked that the media let facts stand in the way.

[...] Well, that’s what happened this last week with my post on real estate numbers that I entered into the Carnival of Real Estate. Alas, I didn’t win — the prize went to a better post from a better writer, Jim Cronin at the Real Estate Tomato — but what I did win was The Best Post of the Week, Anywhere at PoliticalCalculations (permalink most likely this, but it’s not live yet.)
