Abstract
The article proposes a solution of the task of achieving the target regional population size and structure, which would be sustainable in the long term, by means of managing its movement. The significance of this task is justified by the growing concentration of population and labour in a few number of Russia’s regions in the current and projected periods, primarily due to migration processes. The apparatus of matrix equations is used to shape the conditions for reaching the target size and structure of the population. The article presents the estimates of the equilibrium population of the Russian Federation and the possibilities of reaching the target population size in prospect. The demographic forecast of Rosstat up to 2035 in three variants is considered as a target. For each of variants, the required increase of population via birth and immigration is calculated. The possibilities to assess the need in population inflow and to achieve the target population size by using the methodology proposed in the article are shown by the case of the Far Eastern Federal District. It is argued that nowadays a crucial element of social and economic policy in the regions should be creation of new jobs with higher labour productivity and therefore, reduction of the need for foreign labour migrants in the Russian labour market.
population of the Russian Federation, forecasting, regional structure, migration movement, natural movement, balance of population movement, balance of labour resources, model of population and labour force movement
Uneven spatial distribution of resources in terms of investments and labour, is a significant limitation on the acceleration of economic growth in Russia (see, for example,
A similar situation is in the territorial distribution of the employed population: in 1990, 29% of the employed population were concentrated in 10% of the most populated regions while in 2018 this share increased up to 35.5%. Within this group of regions, the share of the city of Moscow, the Moscow oblast, the city of St. Petersburg and Krasnodar krai increased. Employment in other regions of this group decreased compared to 1990. The growing concentration of the employed population is also rooted in internal migration processes.
Other things being equal, the concentration of the population and labour force can result in a decrease in the growth rate of the gross regional product, growth of regional differentiation in the level of social and economic development, changes in the volume and pattern of consumption of goods and services by the population, including an increase in the share of health services, changes in the size of the labour force, its age structure and professional composition, etc.
In the light of such prospects, an important role in the system of socio-economic forecasting should be assigned to the development of methods of analysis and forecasting of population movement of the Russian Federation, including interregional migration. Interregional migration is to be taken into account when solving such problems as depopulation of regions of the Far East or the development of the Russian Arctic by encouraging internal and external migration inflow of both population and labour. Otherwise, the alleviation of problems in some regions could exacerbate them in others, ultimately reducing both the social and economic effects of the measures taken.
Most of modern population forecasts in Russia are based on the cohort-component method (see, for example,
This paper proposes another approach to forecasting the size and territorial structure of the population in the framework of the balance model of movement of labour resources, which takes into account the repeated transitions of people from one state to another (
The demographic forecast elaborated on the basis of this model and presented in this paper, takes into account the trends of interregional migration within two basic periods of time (1991−2015 and 1999−2015). The projected number of births was based on Rosstat calculations (low, medium and high scenarios). Two prospective scenarios were considered for immigration: the constant scale at the level of 2015 and an annual increase of 5%. The combination of these scenarios of fertility, interregional migration and immigration gives 12 variants of forecast scenarios of population size and structure until 2030 (
Among the totality of forecast scenarios, three were considered: low (low birth rate, immigration constant at the level of 2015, base period 1991−2015), median (low birth rate, immigration annual increases by 5%, base period 1991−2015) and high (high birth rate, immigration increases by 5% annually, the base period is 1999−2015).

The forecast reflects the retrospective trends, therefore, it appears to be extremely difficult to overcome this trend in the future without changes in the dynamics of economic growth and its spatial structure.
The task of achieving a particular target structure of the population in some way is the inverse task of the demographic forecast, which determines the prospective size of the population as a result of the dynamics of demographic parameters. As part of this task, it is possible to assess what the basic demographic parameters should be for achieving it.
An analogue of the corresponding task is presented by
Availability of statistical data to calculate the balance of territorial movement of the population enables studying the possibility of achieving the target sizes and proportions of the population distribution between regions. In Russia, with its high existing and projected imbalances in the distribution of population between regions, this issue is highly relevant. However, as far as the authors know, such objective has never been set. This is partly due to the fact that in a market economy, unlike in the Soviet period, many methods of regulating the population size of certain regions like organized recruitment (orgnabor) or instruments to reduce personnel turnover, etc., are not in use.
The need to develop regional strategies for social and economic development actualizes the task of regulating the regional size and structure of the population and the development of tools for its implementation. Prerequisites for its solution are the estimates of current and prospective birth rates and mortality, levels of regional technologies, labour productivity, disposition of productive forces, structures of demand for products, etc.. Without this context it is impossible to determine the target territorial structure of the population and the proportions between its individual groups.
In any case, the task of achieving a certain target structure of the population (or its economic groups) involves the identification of at least two key issues: what the future structure of the population should be and how it can be achieved. The answer to the first question lies in the field of studying the equilibrium size and structure of the population of the Russian Federation. In relation to the distribution of the population between the administrative regions of the Russian Federation, we define the sustainable prospective regional structure, which will remain unchanged over time as a result of maintaining its natural and migration movements at the level of the current year, as “equilibrium”. The size of the population corresponding to its equilibrium regional structure we also define as “ equilibrium”.
Maintaining stable structure over a long period is an objective property of the Markovian processes, which can be applied with some degree of conditionality to the regional structure of the population resulting from its migration movement. In this context, two questions are relevant. Does a balanced regional structure of the population, resulting from the current migration pattern, meet the interests of the country as a whole and of its regions? How to determine the desired (target) regional population structure within the framework of long-term planning? Some aspects of the answer to the first question are presented in (
Plurality of criteria that can be applied to the target regional population structure (efficiency, ensuring the maximum economic growth rate of the country as a whole and its regions, social justice, geopolitical issues, etc.), as well as the existence of different patterns of urban/regional systems complicate the task of determining the desired (target) regional population structure or at least shaping it in a long term. Generally, there exist two “extreme” regional strategies, namely, emphasis on the development of only urban agglomerations and large cities or development of all smaller towns and municipalities. The golden mean between them has to be found. However, studies show that over-concentration of the population in large cities and agglomerations does not provide sustainable economic growth, therefore, the balanced development of cities of different sizes is needed (
Let us suppose that some pattern of the distribution of population (or its particular economic groups) are established and fixed at the state level as target indicators, therefore the long-term methods to achieve them are to be determined. In case of annual revision of the related policies (for example, changes in the number of entrants to different specialties, retraining of personnel, economic incentives to move from one region to another, and other kinds of stimulation) the population and the region authorities would be disoriented. Therefore, the methods of achieving the targets should, on the one hand, be flexible, with the possibility of technical corrections, and on the other hand, be stable in the long term, which will allow the country as a whole and regions to adjust.
The measures aimed to regulate the regional population structure can be classified into three groups: affecting natural population movement, external migration and interregional population movement.
Considering population movement over a certain period of time as a Markovian process described by the probabilities of population movement from one state to another (0 ≤ pij ≤ 1, , , n is the number of states considered), it is possible to determine the equilibrium regional population structure. In the model, states are understood as regions (internal states), as well as sources of population increase and decrease, such as fertility, mortality, emigration and immigration (external states).
The impact of exclusively internal migration of the population on the formation of its equilibrium regional structure can be estimated on the basis of closed migration balances. This balance describes the change in the regional population structure as a result of its interregional movement, excluding dynamics of natural movement and external migration. In this case, the equilibrium regional population structure, which will develop through r periods after the period t, is calculated as N (t-1)×prclosed, where prclosed = pij,, , are the probability matrix of interregional population movement; N (t-1) = (n1(t-1), n2(t-1), ..., nn(t-1)) is the vector population at the beginning of the current moment; n is the number of regions.
An open balance enables assessing the joint impact of migration and natural population movement on the equilibrium regional population structure. The latter is defined by the following formula: , where f = (f1, f2, ..., fn) is the vector of intake of people from external states, determined by fertility and immigration, P = || pij ||, , is the matrix of population movements taking into account natural movement and external migration, k is the number of external states.
Indicators of balance model of movement of population and labour force taking into account repeated movements of people are used as elements of the matrix P (
N (t) = N (t-1)P (t),
where N (t-1) and N (t) are vector lines of regional population size at the beginning and end of the period, respectively; is the matrix of population transition coefficients during the period between regions and external states (its elements calculated on the basis of available statistics are interrelated by the formula , is the matrix the main diagonal of which are the coefficients of settlement in the regions; M (t) = ||mij (t)|| is the matrix of population transition coefficients at each step of movement between regions and the relationship of regions with external states; n is the number of studied states; E is an identity n-matrix. It should be kept in mind that .
Quantitative estimates of changes in parameters of external migration and natural population movement needed to achieve the target regional population structure can be calculated in the model as follows. Let us denote g = (g1, g2,... , gn) as a desired (target) equilibrium distribution of population between regions. Then, if the goal is achievable, there is a single vector f, the elements of which determine the needs of regions in the inflows of the population from external states to achieve the goal: f = g (I–P)-1 = gN, where N = (I–P)-1; I is an identity matrix.

The equilibrium population size in federal districts repeats the dynamics of the equilibrium population of the Russian Federation with some exceptions. Between 2000 and 2010, for Russia in whole the equilibrium population was lower compared to the actual population, while in the North Caucasus Federal District it was growing due to high fertility rates and low mortality rates. Between 2010 and 2016, for Russia in whole the equilibrium population was higher than the actual population, while the Far Eastern Federal District was steadily losing its population (in some years a decrease was also observed in the Volga Federal District). In 2013, which was the most favourable year, the negative gap between the equilibrium population and actual population in the Far Eastern Federal District was the biggest (7.5% at the end of 2013).
The reported parameters of natural and migratory population movements, which were used in calculating the equilibrium population in Fig.
Unlike the target values of the size of employed population in particular administrative regions indicated in some regional development programs, the authors did not encounter assessments of the target regional structure of the population and options for its achievement, taking into account the interests of all regions of the Russian Federation. Therefore, we will take the regional estimates of the population forecasted by Rosstat to 2035 as target ones in terms of achieving the equilibrium state. The authors understand that the demographic forecast of Rosstat is a scenario, not a targeted one, however, we consciously accept such an assumption. Its conceptual meaning is to assess Russia’s need for an additional population inflow (not only for the country as a whole, but also for regions) and to assume that the long-term regional distribution of the population forecasted by Rosstat iss stable and constant (i.e. equilibrium). Thus, the regional need in population will be determined by vector f = (f1, f2,... , fn), and in the country as a whole - by the sum of its regions. At the same time, it is assumed that the structure of interregional population movement will remain at the level of the current (base) year.
By comparing our estimates with the current and/or forecast estimates of fertility and immigration by Rosstat, we can estimate the shortage of population inflow to the country (in general and in the context of regions) in order to establish the regional population structure as an equilibrium, corresponding to the three variants of the demographic forecast of Rosstat.
The result of the corresponding comparisons is represented by three curves in Fig.

In case of the 2000 pattern, with the accepted hypotheses, the period between 2001 and 2035 is divided into three periods. The first period refers to the period up to 2011-2013, depending on the variant. During this period, the actual annual influx of the population from the external states was less than the estimated need (the sum of the elements of vector f). Under the low scenario, the need was estimated as 2.1 million, while the actual inflow varied from 1.5 million in 2001 to 2 million in 2010. The second period starts in 2012 (low variant), in 2013 (medium variant), in 2014 (high variant) and lasts up to 2017. If the population influx from external conditions corresponding to this period could be maintained in the long run, it would provide achieving any of the three variants of target size and structure of the population. However, since 2018 (the third period) within the medium variant of the forecast of Rosstat, taking into account the projected dynamics of the birth rate and the immigration scale as in 2016, the need for population additional inflows from external states arises.
Calculations based on the structure of population movement as in 2016 (Fig.
The appropriate method of calculation enables estimating the need for population influx not only in the entire country, but also in the regional aspect. Regional target population size is set only in the State Program “Socio-Economic Development of the Far East and the Baikal Region”. It sets the target of the population growth in the region from the current 6.2 to 6.5 million persons by 2025. To achieve that, a number of measures are proposed to increase the migration attractiveness of the region for internal and international migrants and to anchor of the newly arrived population in the places of settlement. In terms of migration structure, first of all, the emphasis is placed on attracting labour-age population by creating modern, highly paid jobs in the territories of implementation of investment projects, as well as infrastructure development.
According to the calculations of Rosstat, the “spread” of the possible population size of the Far Eastern Federal District by 2035 is 1.2 million persons depending on the scenario (5.5 million persons for the low variant and 6.7 million persons for the high one; in the medium scenario the corresponding number is 6 million persons). The share of the District in the total population of the country will increase only within the high scenario: from 4.2% in 2019 to 4.3% in 2035, while in the other two scenarios its share decreases to 4.1 or 4%.
Within the framework of our model we can determine the need of the Far Eastern Federal District in additional population inflow to achieve the target population number as defined in the State Program. For this purpose, in all three of Rosstat’s scenarios the population of the Far Eastern Federal District (excluding the Baikal region) is increased to 6.5 million people. Fig.

Source: authors’ calculations on the basis of the Rosstat data.
In order to achieve the declared target, the Far Eastern Federal District needs an additional influx of population during the entire period under review, both reporting and forecasted. In the forecast period, the additional need of the District in population will grow, but at different rates depending on the forecast variant. The highest need for the population inflow in the District will be in the case of realization of Rosstat’s low scenario (up to 57.5 thousand persons in 2035), which is explained mostly by the projected decrease in the birth rate in the District. Noteworthy, the scale of the need for population inflow is roughly the same regardless of the structure of migration flows in 2010 or 2016.
The need for additional population in the Far Eastern Federal District can be achieved by rise in fertility, increase in the number of immigrants, reducing the migration outflow of population, and the encouragement of resettlement of citizens to work in these regions. The actively implemented but highly controversial measure related to granting a plot of one hectare of land in the Far East region, is also aimed at attracting the population from other regions for economic development of virgin lands and encouragement of small and medium size businesses.
The reduction in the growth rate of the working-age population in the late 1960s brought to the forefront the task of increasing the efficiency of the use of available labour resources. In this regard, a large number of studies have been aimed at determining the optimal distribution of labour resources among industries, professions and regions and shaping the ways to achieve it. At present, the issue of setting target parameters in relation to the distribution of population and its economic groups among industries, professions and regions is not on the research agenda. This is probably due to the hope of the market self-regulation which is to establish reasonable proportions “automatically”. However, the studies show (see, for example,
The current trend of active attraction of foreign labour migrants is to some extent a reflection of the mechanism of compensation of the negative effects of an unbalanced economy formulated by
