What are postal codes in Sweden?

Are there any interesting machine learning or data mining projects involving Postal Codes?

• Except for the handwritten zip code recognition. They focus on some application of postal codes or use postal codes as features.

• Answer:

  Here's a mixed bag of aggregated (public-record) datasets, some DM/ML projects and some visualization: 1) http://zip-codes.com is a truly excellent aggregator of all sorts of useful data: e.g. http://www.zip-codes.com/zip-code/94117/zip-code-94117.asp 2) http://CrimeReports.com 3) http://www.census.gov/2010census/ (data, visualization, exploration) is here and the corresponding https://www.kaggle.com/c/us-census-challenge competition (https://www.kaggle.com/c/us-census-challenge/data is here), which also had a https://www.kaggle.com/c/us-census-challenge/prospector#230 (winning site listed there) (Note that the census uses FIPS State, Tract and BlockGroup numbers, not direct zipcodes. You can convert them, with some pain) 4) US Political campaign donor database http://fundrace.huffingtonpost.com was bought by Huffington Post and seems to be have been killed/mothballed (aww!); wonder if they resurrect it for 2014 midterms. Old articles: http://www.huffingtonpost.com/news/huffington-post-fundrace/ http://www.huffingtonpost.com/news/fundrace/ http://www.huffingtonpost.com/2010/09/28/2010-political-donations-_n_741723.html (But the underlying information is public record, anyway) 5) Something neat (that didn't directly use zipcodes, but uses geocodes, so you can easily convert to zipcode) but produced awesome geographical visualizations was: swissnex http://swissnexsanfrancisco.org/News/NewsStories/winning-the-urban-data-challenge for SF,Geneva,Zurich and http://urbandatachallenge.org/winning-projects-2/ There's a 2014 competition starting very soon.
