Finding Good School Districts

One area that perplexes me about california is how drastically the quality of a school district can change in just a few miles. The contrast is exemplified by the difference between Palo Alto, and East Palo Alto. These are literally bordering school districts on opposite ends of the spectrum. I was looking around today for a way to visualize where the good schools are located and found the following tool that displays all of the schools on a map with ratings:

Good time to buy?

The NY Times article this weekend got me second guessing our choice to start dipping our toes in the housing market. We found a real estate agent and started looking at open houses, thinking that now is a great time to buy. The article questions that logic and mentions 3 metrics as fundamentals, but then kind of leaves you hanging. That lead me to start geeking out over numbers...

1) Housing Stock vs. GDP: I was inspired by the somewhat suspicious housingbubblebust.com to use the Federal Reserve Flow of Funds report as a data source. GDP is in table F.6 row 1, and housing valuation data is reported in table B.100 row 4. I plotted them together and got the following:

This looks similar to what is on the housingbubblebust.com site, but a little more up to date. However, this plot doesn't capture the trend of the ratio very well, so I plotted that seperately:

Interestingly, it looks like most of the correction has already happened but it still has a little to drop. Housing prices are within 20% of GDP, and I assume they will remain slightly inflated (above 1.0 ratio) as long as interest rates are so low. I found myself wishing for the same charts for California, but wasn't able to track the appropriate data sources down.


2) Cost of ownership vs. renting:
For this question, I found the NY times Buy vs. Rent calculator very helpful. I also charted Housing Affordability Index for California (along with Santa Clara, and San Mateo Counties) over the past 10 years. The chart is a little misleading towards the end because the reporting schedule changes from monthly to quarterly, but it still gives you a sense that the affordability of housing in CA is near a 10 year high. Given the previous chart, I would really like to see how this data looks before the year 2000.


3) Ratio of median income to median home prices: According to the Census Quickfacts, the median household income in California in 2008 is $61,017. The California Association of Realtors has more up-to-date information on median home prices (through 2009). Q4 2008 is $249,870, resulting in a ratio of 0.244. This number is pretty meaningless without charting it historically. I had a hard time finding complete statistics for median income in Cal. Ideally I'd be able to drill down to the municipal / county level, too.

Hope this research is helpful to others. If you find any other interesting sources of data like this please include them in the comments below.
