Objective: Assay of contemporary structure and age composition of population in the areas of the country desig-nated as ones of the most intensive radiological contamination after the Chornobyl NPP accident.Study object. Population of the most intensively contaminated areas of Ukraine, i.e. Korosten, Narodychi, Ovruchand Olevsk regions of Zhytomyr oblast, Ivankiv and Poliske regions of Kyiv oblast, Rokytne and Sarny regions of Rivneoblast, Kozelets and Ripky regions of Chernihiv oblast. Entire population of Ukraine was the control.
Materials and methods: The State statistical services of Ukraine and their regional offices were the study informa-tion base regarding the distribution of permanent population by gender and age as of 01.01.2017. Demographic,mathematical and statistical, graphical and technological software methods and tools we applied.
Results: An excess of males over females from birth up to 35 years old is found in Ukraine. Similar gender imbal-ance was observed only in Olevsk region. In other age groups, high or very high disproportion in age compositionbeing the most pronounced after 65 years old remains in favor of females, except villages in Sarny region. An aver-age age of population in Ripky (45.9 years), Kozelets (44.5 years), Korosten (42.5 years), Ovruch (42.3 years) andNarodichi (42.2 years) regions was higher vs. the entire Ukraine (41.1 years). The lowest age at that was in Rokytne(30.9 years) and Sarny (33.8 years) regions. The age difference between males and females was from 3.6 years inSarny region to 7.7 years in Ripky region.Сonclusion. There are some differences in age composition of population of the contaminated areas of Ukraine.Rokytne, Sarny, Olevsk and Poliske regions feature the best potential of demographic replacement in the foreseeablefuture. Areas of radiological contamination are different in patterns of population replacement, i.e. progressive, sta-tionary of regressive. The number of children under 15 years old exceeds there the size of population older thanworking age.
