Case-Shiller Index of US residential house prices. Data comes from S&P Case-Shiller data and includes both the national index and the indices for 20 metropolitan regions. The indices are created using a repeat-sales methodology.

There is home page for Indices on S&P website. This provides a table of links but these are not direct file URLs and you have dig around in S&P's javascript to find the actual download locations:

• National index (xls)
• City indices (xls)

To download and process the data do:

python scripts/process.py

Updated data files will then be in data directory.
