According to multiple sources, including the Global Wealth Report 2020 by Credit Suisse and a report by Zippia, approximately 8.8% of US adults are millionaires. This equates to around 22 million millionaires in the US. However, other sources provide slightly different estimates. For example, DQYDJ estimates that there are 15,298,070 millionaire households in the US, or roughly 11.89% of all households. Meanwhile, Investopedia reports that for the first time, more than 1% of Americans are millionaires. Its important to note that these estimates may vary depending on the criteria used to define a millionaire, such as whether or not primary residence is included in net worth calculations.
