Spatial scale, return and onward migration, and the Long‐Boertlein index of repeat migration

Long and Boertlein's (1990) measure of repeat migration can be used to infer the effects of repeat migration with data sets that did not specifically ask questions about such migration. While recent work by Rogers et al. (2003) evaluated how well this synthetic measure matched empirical fixed‐interval measures, the role of spatial scale remains unclear, particularly since scale influences migration levels, spatial structure, and the …
