Is there a similar disaster that can help me determine survival rates?

Short version: 1 million people were left to fend for themselves (a.k.a. there's no room at the inn scenario) through what amounts to a storm of asteroid fragments pulverizing the United States (largest being 4km and scaling down from there) as well as the ensuing impact winter.

Are there statistics available for similar disasters that can help me determine the following?:

• What percentage would die from asteroid impacts (direct, air blast, thermal, etc)?
• What percentage would die from lack of resources (food/water/medical treatment)?
• What percentage would die from anarchy violence over resources?
• How many would be left to attempt attacks on the standing bunkers & shelters?

Thanks!

**Editing to clarify: I apologize for not being more clear.

1. I am not referring to separate asteroids. The key word in my scenario is "fragments." These are pieces of a much larger asteroid which we attempted to divert but instead accidentally blew up (or some similar OOPS), so the pieces are now raining down upon us.

2. Instead of "similar disaster" I probably should have said "similar disasters." I'm thinking of combining statistics from, say the worst faminine in history or the effects of a nuclear bomb (minus the fallout radiation deaths) or the collapse of a major country's government leading to anarchy violence. So I'm looking for something like: "The ____ famine wiped out ____% of its _____ population." or "_____ people were killed in the violence following collapse of _____ government." I can do my own research, just looking for names of events to hunt down.
