As the number of people without stable housing in the U.S. grows, laws criminalizing homelessness have also been on the rise for more than a decade, a report published Wednesday found.

The report from the National Law Center on Homelessness & Poverty, the only one of its kind to survey the entire country, looks at data from 2006 to the present.

The picture it paints is one of homeless people facing more laws that are nearly impossible for them to obey, resulting in fines and punishments that only perpetuate the cycle of poverty and make it more difficult for them to find housing.

Here are some of the biggest takeaways from the report:

The criminalization of homelessness is on the rise.

Theres been a nationwide rise in laws prohibiting sleeping in public, even as emergency shelters are unable to meet the demand for beds. As of 2019, 51% of cities have at least one law banning sleeping in public. Thirteen of those laws have been introduced since 2006.

Tent camping in public is prohibited even more often. Currently, 72% of cities have one or more laws on the books banning it, with cities enacting 33 of those laws since 2006.

The biggest uptick in bans affecting the homeless concerns sleeping in vehicles, which 50% of cities currently ban. Since 2006, 64 laws banning vehicle sleeping have gone on the books. A whopping 22 of them were put into effect in the last three years.

There has also been an uptick in laws banning begging, sitting or lying in public, rummaging and dumpster-diving and loitering.
