Which document contains the high risk maps?

The correct choice is the county actuarials. These documents are essential for understanding the risk associated with crop insurance in designated areas. County actuarials outline the specific terms and conditions of insurance for various crops, including yield data and insurance rates based on historical losses. High-risk maps are included in these actuarials, as they visually represent areas that have a higher probability of adverse conditions affecting crop production, such as droughts, floods, or pests.

County actuarials provide essential information not just about risks but also about premiums and eligibility requirements, enabling farmers and insurers to make informed decisions. Other options like crop insurance policies, farm management plans, and risk assessment reports serve different purposes and do not typically include high-risk maps in the same context or detail as county actuarials.
