Where can I find large data-sets of tweets from people in a certain region (say an entire state or city in the US), during a certain period (say last 6 months, or from June 1st 2015 to June 1st 2016)?
So, for example, a large data-set of tweets from people in Illinois in the last 6 months? Is this possible? Is location something Twitter makes public? Or am I looking at geolocated tweets only?
