Over the past 30 years there have been three unanticipated shifts in m
etropolitan-nonmetropolitan population change and migration: the nonme
tropolitan turnaround of the 1970s, with a migration balance favoring
nonmetropolitan areas; the downturn of the early 1980s when nonmetropo
litan areas lost net migrants as they did in the 1960s, and a more rec
ent post-1990 recovery, with nonmetropolitan net migration rates once
again above those of metropolitan areas. Partial explanations have bee
n developed from the deconcentration and regional restructuring theore
tical perspectives, but there is not yet consensus on how to explain t
his sequence of three migration changes since 1970. There is a need fo
r a general review of these trends, particularly given the recency of
the latest change. Such a review is attempted here. Annual net migrati
on estimates are examined, considering the changing metropolitan-nonme
tropolitan differential, and differences across geographic and functio
nal county types in nonmetropolitan areas. Some differences stand out
across the 24-year period, but the most notable finding is the widespr
ead nature of the turnaround, the reversal, and the current recovery.
There are differences between the present and the 1970s, but a trend t
oward greater retention and/or acquisition of people in rural and smal
l town areas is clear.
