After many centuries of unabated and relentless childbearing, European women, as if by magic, began to limit the number of children they bore. This trend began in France in the late 18th century, where, by 1830 its birthrate had dropped to less than 3 births per family. From France this fertility decline spread, first along linguistic lines to Belgium and parts of Switzerland, before slowly diffusing eastward across the rest of Europe and westward to the British Isles and the United States. This demographic transition was nothing short of a social revolution, made even more remarkable by the lack of new innovations in birth control and in the face of strong opposition by religious, political, and medical authorities. This was a social movement without spokesmen or public leaders that spread through word of mouth among friends, relatives, and neighbors. Its effects on the lives of women and their families would be profound.
Much of our current understanding of this phenomenon in Europe has come from extensive data collected from 600 provinces across Europe by a two-decade long interdisciplinary research project known as the Princeton European Fertility Project (PEFP). Drawing from over 100 years of records across Europe, the PEFP researchers compiled and analyzed the data to map a detailed description of the time course and nature of European fertility. This work remains the most comprehensive source of historical data on fertility across Europe.
A few general observations from the PEFP are notable. For example, most of the European fertility decline (excepting France) took place from the 1870s to the 1920s. Once the fertility level fell by 10% in a given district, its fertility decline continued rapidly and irreversibly. Within provinces, cities led these changes, with surrounding rural areas soon following. The years 1890-1920 were a tipping point, when most (59%) European provinces began to experience declining fertility. Decreasing birth rates were predominantly due to limitation of births within, rather than outside of marriage; neither later age of marriage nor fewer marriages were significant contributors to the observed fertility declines. Thus, this widespread European decline in birth rates was a result of altered reproductive behavior of married couples.
The Czech lands of Bohemia and Moravia fell within these parameters, but finer differences between individual Czech regions were unresolved by the PEFP (possibly because PEFP data was collected while Czechoslovakia was under Communist governance). Therefore, in the late 1980s, Czech researchers Ludmila Fialova, Zdenek Pavlik, and Pavel Veres refined the initial findings of the PEFP with their analysis of up to 218 districts (okres) within Czechoslovakia for each decade from 1800 to 1980. Publishing in 1990 (in Population Studies 44 (1), 89-106), they found that birth rates in the Czech lands began to fall as early as the 1870s, led first by Prague and several contiguous areas of northern and northeastern Bohemia as shown on the map.
In the next decades, additional districts saw significant and persistent reductions in birth rates. The tipping point for both Bohemia and Moravia came in the first decade of the 20th century (1900-1909), when the largest number of districts exhibited reduced fertility. After 1910, the few remaining districts in southern Bohemia and eastern Moravia completed the Czech fertility decline. Consistent with other European cities, Prague lead the way with fertility levels that began and ended lower than in surrounding areas. In Prague, an average of 5.9 children were born from couples marrying in 1860; 4.5 from those marrying in 1900; and 1.6 from those marrying in 1930. On the other hand, for Bohemia and Moravia as a whole, 7.2 children were born per couple who married in 1860; 6.6 children were born of those marrying in 1900, and 2.9 children were born from couples marrying in 1930.
Thus, the idea that a couple should marry, have a desired number of children, and stop reproducing was at the heart of this fertility decline, and as such, was a relatively modern innovation. Research of the PEFP and others (e.g., Fialova et al., 1990) tells a story of a demographic transition that spread, in some ways, like an epidemic across Europe; by 1930 very few provinces remained untouched. Despite Europe’s diverse cultures, the millennia-old tradition of high marital fertility seems to have crumbled almost overnight. Social historians now regard fertility declines as an integral part of the larger process of modernization of a society.
