In the U.S., the share of the population that is millionaire is roughly 9% to 10% , depending on the source and whether the measure is based on adults or the total population.

Quick Scoop

  • A Statista summary puts the share of the U.S. population who are millionaires at 9%.
  • Another source based on UBS wealth data says there were 23.831 million millionaires in the U.S. in 2024, which is about 1 in 14 people overall and roughly 1 in 10 adults.
  • A different wealth brief reports 25.4 million millionaires , or about 9.7% of the population.

What that means

The exact percentage changes a bit because people use different definitions, especially:

  • Adults only vs. total population.
  • Net worth millionaires vs. asset-based measures.
  • Whether the primary home is counted in net worth.

So the cleanest practical answer is: about one in ten Americans is a millionaire.

Bottom line

If you want a single number, use about 9% of the U.S. population.
