Predicted changes, in the years 1990-2010, in the state and structure of productive age population in Poland and in selected European countries and their consequences for external migrations.

Trends in the number and structure of working-age populations in Europe and Poland are projected for the period 1990-2010. Among their predictions, the authors anticipate that "in Western Europe...the working age population will be reduced by...2%. In both Southern and Northern Europe the working age population will grow...by 1.3% and 3.6% [respectively]. On the other hand, in Eastern Europe the population concerned will grow substantially in those years: this growth is estimated [at]...9.1%." A 14.7 percent increase is predicted for Poland.
