Tammer Kamel, a Canadian Data Scientist, has recently post a beta version of Quandl.com, an index of 2 million time series data sets. Tammer says Quandl’s mission is to make numerical data easy to find and easy to use. The site is collaboratively maintained and free with many features including search, browse, download, visualization, merging, and an API.
Here is one of the many datasets that I have been using to research crime related trends.
