In the United States, employment rates at older ages are comparatively high at 62% among 55-64 year-olds against 59% on average in OECD countries in 2016. However, there are large disparities across population groups. Early retirement remains a widespread phenomenon, especially among workers from vulnerable socio-economic backgrounds. Preventing old-age disparities in terms of employment outcomes and retirement income from widening is crucial. This report looks at the various pathways out of the labour market for older workers, and how employers can be supported to retain and hire older workers. It examines the best ways that the United States can promote the employability of workers throughout their working lives and more equal outcomes among older workers.
