<P> The Soviet economical and political system produced further consequences such as, for example, in Baltic states, where the population was approximately half of what it should have been compared with similar countries such as Denmark, Finland and Norway over the years 1939--1990 . Poor housing was one factor leading to severely declining birth rates throughout the Eastern Bloc . However, birth rates were still higher than in Western European countries . A reliance upon abortion, in part because periodic shortages of birth control pills and intrauterine devices made these systems unreliable, also depressed the birth rate and forced a shift to pro-natalist policies by the late 1960s, including severe checks on abortion and propagandist exhortations like the' heroine mother' distinction bestowed on those Romanian women who bore ten or more children . </P> <P> In October 1966, artificial birth control was proscribed in Romania and regular pregnancy tests were mandated for women of child - bearing age, with severe penalties for anyone who was found to have terminated a pregnancy . Despite such restrictions, birth rates continued to lag, in part, because of unskilled induced abortions .
