( CNN ) -- Macau , the world 's biggest casino hub , has overtaken Switzerland in the wealth stakes , being named the world 's fourth richest territory by the World Bank . A new batch of data released by the World Bank showed the former Portuguese colony 's GDP per person grew to $ 91,376 in 2013 , compared to $ 77,196 in 2012 . Only Luxembourg , Norway and Qatar are wealthier , according to the World Bank . Meanwhile , Swiss per capita GDP stayed nearly flat at $ 80,528 in 2013 compared to $ 78,929 the year before . That 's the good business news from Macau . The bad news is that its casino industry 's revenues have declined for the first time in nearly five years , as gamblers turn their attention to the World Cup . The former Portuguese colony made $ 3.4 billion from gambling in June , 3.7 % less than in June last year and down 18 % month-on-month . Macau is the world 's top spot for the gambling industry , reporting a staggering $ 45 billion in gambling revenues last year -- nearly seven times the $ 6.5 billion that casinos in Las Vegas made during the same period . According to analysts , the sudden dip can be attributed to the month-long football World Cup prompting punters to swap casinos for online sports betting . The casino hub has been further hit by a large anti-corruption police investigation last month , which led to a crackdown on an international gambling ring that was operating an illegal $ 600 million World Cup betting operation out of a hotel in Macau .
