This document summarizes the results of a 2010 Swedish Twitter census conducted by Intellecta Corporate. It found that there were over 25 million Swedish Twitter accounts, but only around 36,000 active users who tweeted at least twice in the past month. The majority of tweets came from a small percentage of highly active users, with the top 10% responsible for 80% of tweets and the top 50% responsible for over 98%. The document also shows graphs on when Twitter usage in Sweden began growing and leveling off.
