This document discusses why aging populations and labor markets are important topics, especially at the local level. It notes that employment rates for older workers vary significantly across OECD countries, and that once unemployed, older workers face high risks of long-term unemployment. The OECD has conducted various reviews on policies to promote longer working lives. These reviews recommend actions like pension reforms, training opportunities, and improving work environments. However, the challenges of aging populations are not uniform across all local areas, so policies need to be implemented at the local level to address specific local issues.
