That guy with tattoos in the audience is definitely Qatari born and bread.
Quatar is a very unusual country. It was ruled by the British until about 1970, when pearl diving was it's biggest industry. It was still mainly nomadic. Then they found oil and in the space of 50 years they went from tribes to cities. So, the population is massively foreign, there are about 300,000 actual Quataries, born and bred, but the actual population is 2.7 million. So, massive ex-patriate population and shit tonne of migrant labour. They only give out about 100 citizenships a year, so there are loads of workers (you have to be sponsored by a company to stay) who have been there for decades who don't have naturalisation rights. Very odd the set up, but it explains why young population looks so diverse.
