Suppose someone answers: 18. Or 44. Or 110. What does that tell you? Absolutely nothing. It doesn't say what sorts of crimes they were. It doesn't even tell you "number of crimes per 100,000 people, so you have no basis to compare that number with any other. And "in the last few months" could be 2, 3, 4, or more months. So someone could give you a 2-month figure of 25 and someone else could give you a 4-month figure of 50.
The right question (I'm guessing) is: How safe is it to live in the Alief area? Suggestion: Talk to people who live in the area and ask them about crimes. And talk to the police.
Hope that helps.
