Much has been said and lists have been created by numerous groups and publications with their own ranking of which city tops other cities in terms of its Gross Domestic Product, number of millionaires and all other varying elements. In a city like Hong Kong, where any house and estate owner can easily be considered a millionaire due to the high property and land rate, we take it a notch higher and count the billionaires in these cities instead. The high-net-worth people or the “individuals with net assets of USD $1 billion or more”, or the billionaires who reside in these cities on the list, were taken into account.
