The Lisbon region is the wealthiest region in Portugal and it is well above the European Union's GDP per capita average – it produces 45% of the Portuguese GDP. Lisbon's economy is based primarily on the tertiary sector. Most of the headquarters of multinationals operating in Portugal are concentrated in the Grande Lisboa Subregion, specially in the Oeiras municipality. The Lisbon Metropolitan Area is heavily industrialized, especially the south bank of the Tagus river (Rio Tejo).
