2010 was the only year that the National Institute of Statistics agreed to release the exact percentages ” exceptionally” , while it was estimated that illegal activities accounted for 0.87% of GDP, at 9.4 billion euro .

Of these figures, prostitution contributed an estimated 0.35% of the economic activity in the country which adds up to 3,783 billion euro, while drug smuggling contributed a 0.5% or 5,405 billion euro.
For 2013, although there are not any available statistics, those numbers elegantly have increased by far.
However, European Union’s statistic office Eurostat, gave a deadline until the 1st of September to Member States to calculate the illegal activities that generate significant revenue (drug trafficking – prostitution).

Spain had no objections on the matter, while Italy revised its figures to 3.8% and Britain gave an estimate amount of 12.3 billion euro which is about 1% of GDP for 2013.
