According to the TSA in 2006, the added value of tourism was EUR 13.6 billion, or 2.9% of GDP (Table 3.72). In 2002, TSA data showed that there were some 395 000 employees in the tourism sector, 4.1% of the employed labour force at the time. In 2006, 10.7 million international visitors arrived in the Netherlands, an increase of 7% on 2005. The average length of stay has decreased a little, while the number of overnight stays grew by 6% to 26.9 million. Domestic tourism in 2006 accounted for 17.8 million domestic holiday trips, 2.9% up from 17.3 million in 2005. There has been a steady rise in the number of tourism establishments since 2002 in hotels, camp sites and holiday bungalows, although the number of ANVR travel agencies (Dutch Association of Travel Agents and Tour Operators) has declined while tour operator numbers have stagnated.
