Human fertility in Russia since the 19th century

In more than a decade of research on fertility in the Russian Empire and the Soviet Union, the Office of Population Research at Princeton University has assembled a large inventory of quantitative information. Some of the data from early years are handwritten others exist only in computer printouts. Much of the material was not included in published results for one reason or another. For the convenience of other researchers interested in the population of Russia, selected primary data have been put in machine-readable form.
