Final answer:
The group known as seniors, ages 64-74, is growing in the US. This demographic shift, largely due to the aging Baby Boomer generation, has resulted in a significant increase in the elderly population, which in turn affects health care and social services.
Step-by-step explanation:
The demographic group known as seniors, ages 64-74, is currently growing in the US. This age group is part of the "young-old" category, which is happier, healthier, and financially better off than previous generations. A factor contributing to the increase in senior population is the aging of the Baby Boom generation. By 2030, all Baby Boomers will be age 65 and older, representing a large segment of the elderly population.
Figures indicate that as of 2013, 20% of the U.S. population was over 60 years old, equating to almost 63 million individuals requiring increased medical care and other services commonly associated with aging. The U.S. Census Bureau illustrates that the proportion of the population that is 65 years and older has grown significantly, which has been termed as "the graying of America".
Overall, these shifts in demographic patterns are notable as they have a profound impact on policies, health care, and various social services within the United States.
