Step-by-step explanation:
The correct answer is c. Decline in the elderly population.
Between 1980 and 2014, the trend in aging in the United States saw increased life expectancy, with people living longer on average. Additionally, the baby boomer generation started entering old age during this time period, leading to changes in social institutions and increased demand for housing, elder care, and assisted living facilities. There was also a notable growth in the number of centenarians, with approximately 80,000 centenarians in the United States in 2010. However, there was not a decline in the elderly population; in fact, the number of elderly individuals increased significantly, representing a greater share of the total population.
