A team of population specialists from the United States and Kazakhstan uses heretofore unpublished data of the Kazakhstan Statistical Agency to assess gender and age differences in the propensity to migrate from Kazakhstan for the period 1991-2001. The interstate character of the population movements analyzed means that Slavic, German, and other non-Kazakh ethnic groups are disproportionately represented among the emigrant population, but the key focus is on identifying the differing migration responses of men and women during economic crisis, in this case the precipitous decline in economic activity following the dissolution of the USSR. © 2003 by V.H.
