World Population Ageing 2019

This report is the seventh in the series entitled World Population Ageing. The first report was released in 2002 in conjunction with the Second World Assembly on Ageing convened in the same year in Vienna, Austria. The present report provides a description of global trends in population ageing and includes an in-depth analysis of new measures that offer an alternative perspective on changes in the population age structure. It also presents measures to track trends in economic dependency as a result of changes in the population age distribution.
