Final answer:
True, by 2050, it is projected that one out of every five persons will be over 60 years old, as global populations are aging significantly.
Step-by-step explanation:
The statement that by 2050, one out of every five persons is projected to be over 60 years old is true. Aging populations are becoming a significant global demographic trend, particularly in high-income nations, where the proportion of elderly citizens is increasingly surpassing other age groups. This demographic shift is causing what is commonly known as "the graying of America." Additionally, even in low-income countries, the proportion of the elderly is expected to increase substantially by 2050.
In 2013, the U.S. Census Bureau reported that 20% of the U.S. population was already over 60 years old, a number which represented almost 63 million individuals requiring more medical care and other services. The increasing life expectancy is one of the key factors in this trend. At a global scale, the United Nations 2020 report projects that by 2050, the number of people aged 65 or over will double to 1.5 billion, meaning one in six people will be in this age bracket. These changes have profound implications for healthcare, social services, and economic policies.
