New Jersey has the second-highest percentage of households worth at least $1 million in the country, according to a study by Phoenix Marketing International, a global marketing services firm.

With 3.3 million households, the Garden State has 242,647 whose total worth exceeded $1 million in 2013. That worked out to almost 7.5 households out of every 100 in New Jersey.

Only Maryland had a greater percentage at 7.7 percent.

New Jersey moved up from the No. 3 spot in 2012 when it had 235,292 millionaire households, or 7.27 percent, according to the study.

New Jersey held the top position in 2007 when 7.12 percent of the state’s households -- 228,442 -- were worth at least that much.

Since 2006, the state has floated between the top and third rankings, but the number of top-end households has grown every year.

Despite the growing numbers, New Jersey isn’t minting millionaires as quickly as other states. North Dakota was the leader in 2013, moving to No. 29 in the Millionaire Ranking, up from No. 43 in 2012. Other big gainers in 2013 were Maine (up 11 points to No. 25) and Louisiana (up 10 points to No. 32).

States that are losing millionaires include Nevada (falling 20 points to No. 39), Arizona (losing 13 points to fall to No. 34); Florida, Michigan and Idaho, which all fell 10 spots.

The state with the fewest millionaires is Mississippi, with 3.6 percent, or 40,955 households, wealthy enough to join the elite circle.
