INTEGRATED ASSESSMENT OF THE DEMOGRAPHIC STATE OF RADIOLOGICALLY CONTAMINATED AREAS OF UKRAINE

Objective. Basing on the integrated assessment to conduct a comparative statistical analysis as of 2016 of the demographic state of the areas of Ukraine that are recognized as those with the most intensive radiological contamination due to the Chornobyl NPP accident.
Study object. The population of the regions of Ukraine with the most intensive radiological contamination due to the Chornobyl NPP accident and the population of Ukraine as a whole (control).
Materials and methods. The data of the State Statistics Service of Ukraine and its regional offices were used as information base in this study. Integrated assessment of the demographic situation in a oblast was conducted based on the calculations of the territorial indices and multidimensional average variable on each region. Demographic, mathematical-statistical, graphic, software-technological methods were used in this study.
Results and conclusion. Radiologically contaminated regions of Ukraine differ significantly: both by the number of population (from 5800 people in the Poliske region to 105100 people in the Sarny region), and by the variability in themedical and demographic indicators; bothone from another and compared to data for the country. The results of the calculations of 10 medical and demographic («positive» and «negative») territorial indices and multidimensional average variable (P) as integrative assessment of the demographic state have revealed that the best indicators of the demographic situation in 2016 were in Rokytne (P = 1.249) and Sarny (P = 1.112) regions of the Rivne oblast, while the worse indicators were in Kozelets (P = 0.363) and Ripky regions of the Chernihiv oblast. The demographic situation of the Olevsk region of the Zhytomyr oblast (P = 0.947)was the closest to the national average one. Poliske, Narodychi, Ovruch, Ivankiv and Korosten regions take intermediate position as comparedto the regions of Rivne and Chernihiv oblasts (P = 0.618–0.742).
Key words: Chornobyl accident, radioactively contaminated areas, demographic situation, integrated assessment.
