The Consumer Financial Protection Bureau (CFPB) on Wednesday released new data that shows the number of people nationwide who have credit card debt.

The numbers were released by the agency as it looks to crack down on people who misuse credit cards.

Here are some of the highlights: In 2014, 7.4 million Americans had credit card debts.

By the end of March, that number had grown to 15.3 million.

About 1.3 billion Americans had $300 or more in credit card balances.

The majority of those Americans were either unemployed or were in families that could not afford to pay off their debts.

In 2014 there were 2.3 times as many Americans with credit card accounts as there were jobs.

The CFPB reported that 1 in 4 Americans had an outstanding credit card balance in the third quarter.

And in 2014, 6.5 million Americans owed more than $10,000 on credit cards, up from 1.5 in 5 in 2013. 

The agency also released figures from its Survey of Consumer Finances, a survey that measures how consumers use credit cards in the U.S. The report showed that consumers spent about $1.7 trillion on credit card and debit card transactions in the United States in 2014. 

That is up from $1 trillion in 2013 and $2.2 trillion in 2012. 

“Credit card debt is a major cause of economic hardship, especially among households earning less than $60,000 per year,” said Acting Director Julie Parker.

“The data collected by the CFPI will help us improve the way we collect information about the types of people and businesses that are using credit cards and the type of purchases that they make, so we can make smarter decisions about who and what we support in our communities.” 

More: The CTPB report also showed that consumer spending increased by 6.6 percent in the first quarter of 2015, which was the biggest increase on record.

That was followed by a 3.9 percent increase in the second quarter.

The average amount of spending increased 8.6 percentage points in the quarter compared to the previous year. 

In the second half of 2015 consumers spent $3.3 trillion on debt, up 5.4 percent from the same period in 2014 and the highest in history.
