RESUMO
The high level of children health, according to official statistics, (about 80% of children of I and II health groups), raises doubts in quality of information. Analytical methods of processing of databases of the official state statistics, based on interregional comparisons, and also comparison of the main indices of public children's health and multidimensional classifications are offered As a result of the hierarchical cluster analysis of the main indices of children's health the poor quality of medical examinations and health survey is confirmed. The best situation concerning children's health and quality of information is noted in 19 regions, mostly European part of the country, the worst--in six national regions of the North Caucasian, Southern and Siberian Federal Districts.
