Rising Elderly Population in the US

Life-Span Perspective

The life-span perspective sees human development as a lifelong process rather than one that stops after adolescence; instead, it continues into adulthood through old age. This perspective divides human development into two phases: an early phase of childhood and adolescence, in which there is a lot of growth and change, and a later phase that includes young adulthood, middle age, and old age, where changes slow, but abilities continue to develop? (Cavanaugh & Blanchard-Fields, 2011).

The Four Key Features of the Life-Span Perspective

According to Paul Baltes, there are four features of the life-span perspective—multidirectionality, plasticity, historical context, and multiple causation (Cavanaugh & Blanchard-Fields, 2011, p. 4). Human development involves gains and losses that occur at the same time throughout one’s lifespan. For example, some cognitive abilities such as vocabulary may continue to improve, but things like reaction time tend to decline.

Plasticity refers to the ability to change in response to positive or negative experiences. It is present even in late adulthood, as people can develop new skills or improve existing ones through training and practice. However, not everyone has or maintains the same plasticity over time.

Every person’s development is also shaped by his particular historical period and culture. For example, someone born in the early 20th century experienced different life conditions and social norms than someone born in the 21st century, that person’s development is obviously going to be a little different. This feature views socio-historical influences on growth and development? as an important consideration.

Finally, development is influenced by a biological, psychological, sociocultural, and life-cycle forces. These forces interact to shape the trajectory of a person\\\\\\\'s development, making it a multi-faceted process that can\\\\\\\'t be fully understood from a single angle?? (Cavanaugh & Blanchard-Fields, 2011).

Changing Population Demographics

Countries around the world have populations that are aging. They are experiencing lower birth rates and increases in their older adult populations who are living longer. For example, Japan has the highest rate of aging among industrialized nations. Similarly, Canada has an adult population that is expected to increase by 126% between 2000 and 2030?. This trend means there will be challenges for nations with already strained health care systems and limited social support systems? (Cavanaugh & Blanchard-Fields, 2011).

The diversity of older adults is also increasing, particularly in the United States, where minority groups like Hispanic Americans, Asian Americans, and Native Americans are seeing faster growth in their elderly populations compared to European Americans. This growing diversity will have effects for health care and social services, as different cultural backgrounds tend to require different approaches to and types of care??.
