We considered the specifics of mapping natural population changes of the Irkutsk oblast. The Irkutsk oblast is a non-uniformly populated territory in its main part with a rare network of settlements (mainly of focal character) with the exception of the south along the Transsiberian Railway. We applied the dasymetric method by V.P. Semenov-Tyan-Shanskii adjusted for Siberian realities to identify local characteristics of the population distribution. The boundaries of the territories of areal settle ment were determined by the spot method with a buffer radius of 3 km from the borders of the settlement. Continuous lines of settlement formed by single or double chains of settlements along the transport routes, being the axes of economic activity, border upon the territories of areal settlement. A defining characteristic of this method is that the calculation of natural growth and further mapping was carried out not according to administrative units, but in the context of settlements and populated areas, ignoring the boundaries of municipalities. A cartographic study enables the identification of patterns and detailing of natural migration, taking into account the characteristics of the actual distribution of the population of the Irkutsk oblast.
