A few days ago Marvin Reuver and I received data about the number of Twitter users per city in the Netherlands from Michiel Berger from the Twittergids. The Twittergids contains 238,000 registered Twitter users in the Netherlands as of January 14, 2011. I then visualized this information with my Digital Methods Initiative colleague Esther Weltevrede where we focused on the top 25 cities represented in the Twittergids.

As you can see the Provinces of Zeeland and Drenthe are not represented in the top 25. Another interesting finding in the data is that users from the Provinces of Friesland and Limburg often associate themselves with the provinces and not with particular cities.

This the second map of the Dutch Twitter population according to the Twittergids data. In the first part I visualized the top 25 Twitter cities in the Netherlands. In this follow-up image Esther Weltevrede and I looked into the relative number of Twitter users per 1000 inhabitants for each province. Color density is relative to the highest penetration (province of North Holland).
What is striking is that the province of Groningen has a relatively high number of Twitter users per 1000 inhabitants.
