In the U.S., the best public estimate I found is that there are about 430,000 households with net worth of $30 million or more. Since $31 million is just above that threshold, the number of people or households at that level is probably a bit under 430,000 households , but the exact count for exactly $31 million isn’t usually published separately.

What that means

  • The figure is usually reported as households , not individual people.
  • A household can include one person or multiple people, so the number of people with $31 million is not the same as the number of households.
  • Public wealth data tends to be grouped in broad brackets, which is why exact $31 million counts are hard to pin down.

Practical estimate

If you mean households worth at least $31 million , the number is likely in the hundreds of thousands , and the closest public benchmark is about 430,000 households at $30 million+. If you mean individual adults personally worth $31 million , the count would be lower than the household figure, but I would not want to give a fake precise number without a dedicated dataset.

Data note

Wealth statistics from sources like the Federal Reserve are often shown by percentile or wealth band rather than exact net-worth points, so estimates around $31 million are usually inferred rather than directly counted.

TL;DR: The closest public estimate is about 430,000 U.S. households with $30 million+ , so the number at $31 million is probably slightly below that, not an exact published count.
