Abstract:
OBJECTIVE: To identify the existing demographic problems basing on the data of All-Ukrainian Population Census for 2011 and as at 01.01.2017 related to the population size and composition in the areas most radiologically contam- inated due to Chornobyl NPP accident.Study object. Population of the most intensively contaminated areas of Ukraine (areas of radiological contamina- tion - ARC), i. e. Narodychi, Ovruch and Olevsk regions of Zhytomyr oblast, Ivankiv and Poliske regions of Kyiv oblast, Rokytne and Sarny regions of Rivne oblast, 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 related to the distribu- tion of permanent population by gender and age as at 01.01.2017, as well as data of All-Ukrainian Population Census for 2011, were the information base of the study. Demographic, mathematical and statistical, graphical and techno- logical software methods and tools were applied. RESULTS: There are significant differences in size and composition of the population of the ARC of Ukraine. Gender and age structure of the population living in the ARC, similar to that living in Ukraine in general, changes over time. The whole shape of demographic pyramid of Ukraine indicates that the share of over-60 age group in the popula- tion increased in 2017, whereas the population of the same age living in the ARC is rapidly disappearing. Also there is a significant regional variation of ageing levels of the population living in the radiologically contaminated areas. CONCLUSION: The analysis of pyramid slopes indicates that both in 2001 and in 2017 the most rapid change of pop- ulation size occurred in Rokytne and Sarny regions of Rivne oblast.
