“According to Facebook, between six million and seven million people are active on Facebook monthly. There are 7.3 million Facebook accounts all told in Belgium,” Demeyere explained. “That does not take into account the language or active status of the accounts.”
Some 3.2 million people are active on Instagram in Belgium.
However, Twitter does not give advertisers figures by country or language. “Twitter is always quite active and has many users,” Demeyere said. “We estimate users in Belgium at many hundreds of thousands.”
