    The demographic situation in Penza region under the reforms of the administrative-territorial division in the 1920–1930s by Ya.V. Tereshchenko

    Published 2025-08-01
    “…The obvious unevenness of filling the source base on population movement in the first half of the 20th century forces researchers to develop statistical mod-els and use extrapolation or the balance method to obtain the necessary data. But in light of significant administrative and territorial changes in demographic behavior and composition of the population, general models are not always applicable and can give conflicting results. …”
