[Demographic systems and supranational systems: European fertility from 1952 to 1982].

"The analysis of fertility for 22 European countries and 8 Soviet Republics between 1952 and 1982 reveals different evolutionary models for socialist Eastern Europe and capitalist Western Europe. These models function as attractors (in the sense of fractal geometry) and suggest that demographic evolutions occur at a supranational level. Is it a matter of a bifurcation related to the geopolitical division established after 1945? Or should it rather be seen as a resurgence of the old historical division which cuts Europe into two parts along either side of a line from Trieste to Saint Petersberg?" (SUMMARY IN ENG) excerpt
