Twitter doesn’t disclose how many members it has, so it has been hard to determine how many people that use Twitter in Sweden. I tried to calculate a number in June 2009 using a survey by Sysomos that showed that 0.54% of the accounts were from Sweden. My estimate landed at 75,000 Swedes on Twitter.
Now, Sysomos have now published a new report, in which they have studied 13 million unique Twitter accounts that demonstrated tweeting activity within the period from Oct. 16, 2009 to Dec. 16, 2009. The US is still by far the largest country, but it’s dominance has decreased as the service has expanded more rapidly outside the US, with a very fast growth in for example Brazil (the US dropped from 62.1% share in June to 50.9% now.
Sweden is still in the top 20 chart but has slipped one spot from 18 to 19 and the share has decreased from 0.54% to 0.50%.
Sysomos also looked at the number of tweets by country, and in that chart, Sweden is not among the top 20 countries.
So how many Swedish Twitter accounts are there then? Hard to tell, but according to Twitter COO Dick Costolo, the micro blogging service had more than 58 million global users in November 2009. Here is a quote from a chat with Michael Arrington of TechCrunch.
MA: What about user accounts?
DC: Yeah I won’t say that, but 58 million undercounts it.
So, taking these to figures into account, there should be somewhere in the range of 290,000 Swedish accounts, which sound like a lot. If the statistics from Sysomos are correct, they have at least found 65,000 Swedish accounts (0.50% of 13 million active). What springs to my mind is that considering the extreme growth for Twitter, it might not be long before more Swedes are tweeting than blogging. By the end of 2010, that might actually be a reality.
