Minting a million-dollar fortune isn't the remarkable feat it used to be.
It remains a marker of immense wealth, but the club is growing ever more crowded, with nearly 33 million people across the globe now laying claim to fortunes in excess of $1 million, according to estimates by Credit Suisse in its most recent Global Wealth Databook. 
The US alone claims 13.6 million adults with a net worth above $1 million — that's 41% of all the world's millionaires and more than the next eight countries combined. 
Switzerland, however, has the most millionaires per capita: Nearly 12% of the adults in the country are millionaires, or one out of every 8.6. 
The millionaire population isn't necessarily a indicator of broad wealth within a country. Despite having the most millionaires by a gaping margin, the median wealth for adults in the US is only $44,977. Of the 18 countries with more than 200,000 millionaires, that's a lower median wealth figure than all but Germany ($42,833), Sweden ($39,692), and China ($4,885). 
Below, Business Insider has ranked the 18 countries with the most millionaires — that's all fortunes above $1 million, including the billionaires — based on Credit Suisse's annual wealth report (you can read the full report here). We've also included the country's population and median wealth for comparison purposes.
