Every year, more and more people in the United States become millionaires. This number reached a new high in 2019 when over 10.2 million households reported a net worth of over 1 million dollars. This is roughly the equivalent of Sweden's entire population, which checks in at just over 10 million people. While there are over 10 million people in the US who qualify as millionaires, almost none of them come even close to the status of being a billionaire. There are only 621 billionaires in all of America, while Sweden has 14 billionaires.
