RT Journal Article SR 00 ID 10.1068/a100475 A1 Rogers, A. A1 Raquillet, R. A1 Castro, L.J. T1 Model Migration Schedules and Their Applications JF Environment and Planning A YR 1978 FD 1978 VO 10 IS 5 SP 475 OP 502 AB This paper considers and contrasts two alternative approaches for capturing the regularities exhibited by age patterns in observed migration rates. The mortality approach is considered first and it is shown how such an approach may be used to infer migration flows from two consecutive place-of-residence-by-place-of-birth census age distributions. The fertility approach is considered next, and techniques for graduating migration age profiles are described. The advantages and disadvantages of both approaches are then briefly assessed.
