This paper turns to the indicators that are derived from the issues of information society (IS), information communication technology (ICT) as well as e-business/e-commerce (EC). It aims to explain the concepts, methodologies and conventions used in the calculation of these indicators and the measurement issues that arise both in the international and local levels. The paper does not seek to describe in detail every indicator that appears or ever has appeared. Instead it focuses on the key indicators or groups of indicators which appear in the associated issues between IS, ICT and EC which have conceptual or methodological aspects which are worthy of explanation. It follows by the policy implication of OECD recommendation as a sound advice to the policy makers.
