Explanation:

The US Bureau of Labor Statistics (BLS) is a government - funded organization. It has the resources and mandate to collect, analyze, and publish accurate and comprehensive data on various labor - related aspects, including retirement age trends. A bank teller may have limited access to generalized data on retirement age trends. Social media groups for retirees may have anecdotal or self - reported information which may not be representative or reliable. A financial planning magazine may have some data but is likely to be more biased or less comprehensive compared to the BLS.
