In the late Imperial period, a significant share of population of European Russia has demonstrated improved demographic indicators. The most important sign of demographic modernization is individual birth control. The available data suggest that transition from spontaneous fertility to the controlled one was first noted in St. Petersburg residents around the middle of the XIX century, disseminating among the entire urban population in the second half of the century, and extending to the rural population in the early twentieth century. Commencement of the demographic transition in Russia has been neglected by researchers for two reasons. First, demographic processes were studied country-wide, without any breakdown on urban and rural areas. With this approach, the urban population, accounting for only 10% in 1863 and 15% in 1914, blended with the general population; therefore, it was difficult to understand specifics of its reproduction. Second, age-specific and total fertility rates were not included in the analysis.
