I agree with the first comment "no free lunch!", getting data for writing your own thesis can not be achieved using this way, as you may need some detailed data, no?. Mostly people do gather data by conducting survey or buy the qualified data set from some agencies.
You can get some data visiting this website http://www.nsc.gov.la/ and if you want more detailed one, visit them and buy it.

cheers!
