The statistics of population health and development of public health system is incomplete. Mortality values can be analyzed for 5-year intervals, while morbidity is represented for the following age groups: children, adolescents, adults aged 20-39 and 40-59 years. The authors suggest revising the structure and volume of statistical data on morbidity with regard for age and sex for 5-year intervals, which will help more reliably and correctly solve modern problems of public health.
