But, what are the statistics regarding the risk in renting to them? 

Yes the news cycle seems to perpetuate outdated statistics, partially due to political concerns.

Per every doctor and statistic on this.

Too many people with low education and poor understanding of statistics that use the virus as an excuse for EVERYTHING.

I would like to know where he got this statistic about 10 years and out of the industry.

I wouldn't have thought it was a big deal until I Googled trampoline statistics....guess they are quite dangerous.More than 1 million people went to emergency departments for trampoline-related injuries between 2002 and 2011, with nearly 300,000 of those injuries involving broken bones, according to a new study.And these injuries don’t come cheap — the Journal of Pediatric Orthopaedics studyshowed that the total emergency department expenses for them was $1 billion, and more than $400 million for fractures specifically.What you really care about is making sure that they are taking the risk so just create a lease addendum that gives them permission and makes them assume liability.  

As the saying goes, there are lies, damn lies, and statistics. 

Does anyone have statistics to back that up?  

Another helpful website is www.city-data.com, which provides free statistics you may find useful.

One problem with a lot of the online crime maps and statistics is that they usually don't take into account the density of a neighborhood.
