We offer next some examples of JRC experience in the quest for a methodology for ensuring quality of composite indicators including the use of uncertainty and sensitivity analysis. Finally, we analyse two crucial issues in composite indicator building such as correlation and compensability, which have not received the necessary attention. }, title = {Statistics, Knowledge and Policy: Key Indicators to Inform Decision Making }, url = {}, volume = {}, number = {}, journal = {}, pages = {359-351}, issn = {}, publisher = {}, doi = {} }
