Ask HN: Where do you get data?
I am interested in playing around with popularity algorithms, graph theory algorithms, trying out some map coloring algorithms, etc...
All of these require data though, and I'm not sure where to get it. So I was wondering if people on HN have good places to get data.

- byoung2 17y agoUsually the governing body that oversees that industry will have tons of data. In the US, there is a governing body for everything, either a gov't department, or a similar organization. I'm not sure what type of data you need, but here's where I have gotten data to work with: Population data - US Census (http://www.census.gov/main/www/access.html http://www.census.gov/main/www/access.html) Food data - USDA (http://www.ars.usda.gov/Services/docs.htm?docid=8964 http://www.ars.usda.gov/Services/docs.htm?docid=8964) SAT stats - College Board (http://professionals.collegeboard.com/data-reports-research/sat http://professionals.collegeboard.com/data-reports-research/...) I could go on and on...try a search for {subject} statistics and you should get some ideas
- jacquesm 17y agoI treat the www as one giant database... The nice thing about that is that it is all real world data, so quite messy. That gives you a good grip on what it takes to massage data before it becomes usable, and it also gives you some control over the level of abstraction.
