Twitter was asked 11 times by the UK government to deliver information about its users in the first half of January 2012, it has said.
In 18% of occasions (or about two) it complied with those requests.
In America it received 679 requests from the government, and complied with 75% of them.
On one occasion Twitter was also asked by either the police or a government agency to remove a message - but did not eventually do so.
The social network released the data, it said, to better inform its users about how it treats private information.
The transparency report was "inspired by the great work done by our peers @Google", Twitter said - referencing a similar data release by the search engine giant.
Twitter also said that in the first half of 2012 alone it received more takedown requests as a whole than in 2011.
The company also detailed the number of copyright takedown notices it received - though did not specific in which countries the claims were made.
It received 3,378 notices this year so far, and 38% were complied with.
It said it would try to ""help inform people, increase awareness and hold all involved parties – including ourselves – more accountable".
