The best way to determine if crime levels are "OK" for you is to call the police non emergency line (311 if you are in Charlotte) and talk to the officer who patrols the area. Talking to local residents also will usually help you paint a good picture. If you appreciate an answer, please give "thumbs up".

My advice to you is to go to the charlotte police department website and look at the crime stats for the area you are looking in. That is the most comprehensive site I have found for looking at crime statistics in an area.
The website for them is http://charmeck.org/city/charlotte/CMPD/Pages/default.aspx
If you click on the crime stats you will get the statisitcs for the area. Regarding whether it is a safe area or not is dependinet on what you perceive to be safe and your understanding and view of safe may not be the another person adn vice versa.
So you will have to evaluate the site and decide if it is a safe area for you and your family.
