Percentage of posts with Location null


Help me: we are developing a website that shows the tweets on a map, but it will be successfully only if I can get the location from tweet. As we tested, most of tweets doesn’t have location due to the user didn’t share it.

What I need to know is: is there any research about it? For example, showing that 10% of all tweets doesn’t have location. Any percentage?


I believe there’s some information in this talk from our Flight conference. The number is quite small.
