Groningen is a 200,000 sized city in the north of the Netherlands. It is an old city with the echo of a bygone era of the Hanseatic League sometime before 1800. A university city, about 26% of the population are students and the average age is about 35. Not particularly special for a university city. But there is more.
In 2014, Groningen only having 1.2% of Netherland’s population, held 10% of the Deloitte #fast50 and 20% from the #risingstar companies. Not only that, but it had been steadily growing since 2012 and was outperforming any other relevant city in the Netherlands.
