A new study found that the U.S. Department of Homeland Security's inconsistent reporting of data can lead to a skewed perception of the state of border security.

The study by the Bipartisan Policy Center, a think tank in Washington, was released this week.

The report found that inadequate data collecting and reporting practices at the parent agency of the U.S. Border Patrol creates a misperception about the true state of border security.

The study's authors argue DHS should collect and report more data to get a clearer picture about what's happening at the border. That would include better tracking how many people cross the border and how many overstay their visas, among other issues.

Customs and Border Protection spokesman Michael Friel said the department is reviewing the report but not answering any questions.
