The paper studies the relationships and the dependencies among the several indices, designed by the international organizations, which are used for the assessment of the economic, social and technological (mostly information society related) development. Examination and analysis of a correlation between these indices can reveal the interesting dependencies. The indices assessing the level of a country's competitiveness, corruption, e-participation, e-readiness, etc. are studied and the interdependencies are also investigated. The correlation coefficients between the individual indices are calculated and the identified dependencies discussed.
