title: Buffon's needle and the estimation of migration distances.
abstract: "A procedure is suggested for estimating migration distances from data on the proportion of migrants crossing regional boundaries.  The method makes use of Buffon's needle, a problem in geometrical probability from the eighteenth century.... The procedure is described for various scenarios that differ in their assumptions about region shape, the spatial distribution of population, and the distribution of migration distances.  An application to migration distances in the United States is given, and additional attention is given to the estimation of intraregional migration distances." (SUMMARY IN FRE)
