Nominativnye istochniki v kontekste vsemirnoy istorii perepisey: Rossiya i Zapad [Nominative Sources in the Context of the World History of Censuses: Russia and the West].
Population statistics were complemented with records of vital events in the church protocols from the 16th century. In addition, from the 18th century onwards, some countries conducted annually updated population registers. Combining census information from parish registers and other nominative sources of data provides a unique opportunity — to construct a historically continuous population register. In the late 20th century, some Western European countries started to combine their population registries with other electronic sources for the construction of national censuses.
Since the range of nominative sources in the West has been identified, digitized and largely introduced in scholarly work, while in Russia this process has just begun, it can be argued that the future of innovative historical demography lies in Russia.
