The census says 57 million Americans own mutual funds ... or 50.3% of the population.

That’s incredible!!! That may or may not include their 401Ks and IRAs.
And it doesn’t include people who prefer to buy stocks, bonds and other investment vehicles!!!
57 million is 50.3% of the population? The adult population, maybe? I don't think so.
Nationally, there were 217.8 million people age 18 and over; 35.9 million people age 65 and over
