The number of Americans confirmed to have renounced their citizenship has hit a new high, up 26 percent from 2015, to a new record 5,411, according to government data.

The IRS reportedly publishes the names of those individuals quarterly. Before 2011, fewer than 1,000 individuals chose to expatriate each year, the data found.

Still, many cases were not counted, according to Forbes. The report did not show why many Americans made the decison, although money could certainly be a factor.

The number of Americans renouncing citizenship had set a record for 2015 as well, up 58 percent from the previous year, Forbes pointed out.

Some of the most recent Homeland Security data showed that more than a million legal immigrants to the U.S. received green cards in 2015.
