Where are the safest areas?

I will be moving to DC from the west coast for a job. I will be visiting sometime next month to look at some areas to live in the DMV. However, I looked at some of the reddit posts and people complain about crime A LOT. It worries me frankly. I would like to ask what are some of the more safer areas to live in, you can also include areas in Maryland or Virginia as i’m open to living outside the DC city. I will be visiting next month and looking into this. Thank you all!
