Unified population register as a source of conducting socio-demographic analysis

The article deals with the analysis of demographic characteristics based on data from unified population register. The role of population registers, which are considered the most important sources of population data, is examined. The possibility of a wider use of the data of the unified population register in socio-demographic research is studied. Demographic characteristics are analyzed in the context of the COVID-19 pandemic based on data from individuals integrated into a single registry for experimental assessment. Experience shows that although data from population registers are currently used in demographic research, there is no approach to using data from other government registers. One of the main features of conducting demographic analysis using data collected in different state registers is the presence of a single identification number for each person. In the study, the information on individuals is presented by hypothetical data taken from two separate registers (population registers and health registers). A dataset on 1,000 individuals was combined into a single register. In this dataset, personal data and information about health of the population were collected. The dataset includes each person's PIN, gender, age, position, number of family members, nationality, chronic diseases including diabetes, bronchial asthma, COVID-19 infection, death from COVID-19, recovery from COVID-19. The obtained results show that the creation of a single integrated register based on the population register — electronic demography system — requires an increase in the number of available statistical indicators, integration of various state registers for a more detailed analysis. This will allow processing data and performing statistical analysis more thoroughly and for a longer period of time.
