A USA TODAY survey finds that almost a quarter of Americans have at least temporarily stopped buying online because of security concerns.

A full 24% of those surveyed said they had stopped buying anything online in recent weeks because they were concerned about the safety of information they might put online, according to poll. More than 55% said they had cut back on the number of Internet sites they used and were only going to large, well-known companies they were confident were safe, said USA TODAY.

The poll found that users are also keeping a closer eye on their accounts, with 55% saying they had started checking banking, investment and credit card sites more often for signs that someone had hacked into their accounts.

The poll found that people with less education and lower-incomes were more likely to stop buying anything online. Those with more education and higher incomes were more likely to have changed passwords and cut back on the sites they use, said USA TODAY.Thirty percent of people who had not attended any college had stopped buying online, compared to 16% of those with college degrees.

Of people with incomes less than $30,000, 34% had stopped buying online compared to 15% of those with income of $75,000 or more. Sixty-four percent of those surveyed said they had changed a password in response to security breaches, according to the poll.

Higher incomes and more education were linked to changing passwords. Sixty-six percent of those with college degrees and 73% of those making $75,000 or more, had changed passwords, compared to 56% of those with no college and 55% of those with incomes less than $30,000, said USA TODAY.
