A recent Business Insider report has shed light on several interesting facts regarding America’s labor force.

It is no secret that the global average age is increasing. This is especially true in first world countries, where birth rates are constantly declining while life expediencies are either increasing or stagnant at approximately 70-85. One result appears to be that millions of Americans are choosing to work past 65, and it isn’t due to a lack of retirement funds.

More retirement-age Americans, especially baby boomers, are working than ever before. The reasons for this are not the negative stories that have been floating around, either. The majority of retirement-age Americans who choose to continue working are those in the best situation to jump into retirement. This demographic is primarily composed of highly educated individuals with high incomes, according to Lincoln Plews, a Research Analyst at United Income. This includes approximately one in five retirement-age individuals, or 10.6 million people who are either working or looking for work. In fact, the biggest reason for the current trend appears to be that retirement-age Americans are just healthier than they used to be.

For Americans born before 1960, the full retirement age at which point you may receive your full social security benefits is 66 years and 10 months. You can begin claiming reduced social security benefits at 62, or wait until you’re 70 to maximize your monthly payouts.
