The U.S. Department of Homeland Security is responsible for controlling the flow of goods and people across the U.S. border, but compelling methods for producing estimates of the total flow of illicit goods or border crossings do not yet exist. This paper describes four innovative approaches to estimating the total flow of illicit border crossings between ports of entry. Each approach is sufficiently promising to warrant further attention.
