How many people have $3000000 in savings in the USA?

I'm curious to know, just how prevalent is it for individuals in the United States to have a savings of three million dollars? Is this a common occurrence, or is it something that only a select few can boast about? Given the wide range of income levels and financial situations in the country, it's intriguing to ponder the demographics and circumstances that might lead someone to accumulate such a substantial amount of savings. Do you have any insights or data that could shed light on this question?
