The Doha Airport day offices are strategically located in a new building close to the international airport on one of the city's major arterial roads. Doha is the capital city of Qatar, with over 80 per cent of the nation's population residing here or its surrounding suburbs, and is also the economic centre of the country. Doha's economy is built on oil and natural gas revenue, but the Qatari government is rapidly trying to diversify the Qatari economy. Construction companies have thrived amid all this development. Doha Airport Centre is situated on D-Ring Road, which provides good access to central Doha, the airport and northern Qatar. Hotels, bars, cafés and restaurants are nearby.
