The most expensive and richest cities in the world A report by UBS
15 September 2012: The UBS survey of 72 international cities found that employees in Zurich, Geneva and Copenhagen had the highest gross earnings. Although Copenhagen is still in the top three of the rankings, it used to be number one in 2009. After deduction of taxes and social security contributions, however, Luxembourg overtakes Copenhagen due to the higher level of deductions in the Danish capital. Delhi and Mumbai bring up the rear of the earnings rankings, where workers receive only around six per cent of the average Zurich wage.
