When it comes to producing millionaires, the U.S. still leads the pack.

Between July 2013 and July 2014, the ranks of Americans with a net worth exceeding $1 million grew by 1.63 million, or more than one-third of the 3.84 million adults worldwide who saw their net worth exceed $1 million over that span, according to a new report on global wealth from Credit Suisse. Overall, the U.S. was home to around 14.2 millionaires, or more than 40% of those in the world.
