SOCW 6210 Life Span Interview
SOCW 6210 Life Span Interview
Life expectancy, often abbreviated to LEB (for Life expectancy at birth), is a statistical measure of the average time an organism is expected to live, based on the year of its birth, its current age and other factors including gender. The most commonly used measure of life expectancy is at birth, which can be defined in two ways. Cohort LEB is the mean length of life of an actual birth (all individuals born a given year) and can be computed only for cohorts born many decades ago, so that all their members have died. Period LEB is the mean length of life of a cohort[] assumed to be exposed, from birth through death, to the observed at a given year.
National LEB figures reported by statistical national agencies and international organizations are indeed estimates of period LEB. In the and the , LEB was 26 years; the 2010 world LEB was 67.2 years. For recent years, LEB in is about 49, while LEB in is about 83. The combination of high and deaths in young adulthood from accidents, epidemics, plagues, wars, and childbirth, particularly before modern medicine was widely available, significantly lowers LEB. For example, a society with a LEB of 40 may have few people dying at precisely 40: most will die before 30 or after 55. In populations with high infant mortality rates, LEB is highly sensitive to the rate of death in the first few years of life. Because of this sensitivity to infant mortality, LEB can be subjected to gross misinterpretation, leading one to believe that a population with a low LEB will necessarily have a small proportion of older people. Another measure, such as life expectancy at age 5 (e5), can be used to exclude the effect of infant mortality to provide a simple measure of overall mortality rates other than in early childhood; in the hypothetical population above, life expectancy at 5 would be another 65. Aggregate population measures, such as the proportion of the population in various age groups, should also be used along individual-based measures like formal life expectancy when analyzing population structure and dynamics. However, pre-modern societies still had universally higher mortality rates and universally lower life expectancies at every age for both genders, and this example was relatively rare. In societies with life expectancies of 30, for instance, a 40 year remaining timespan at age 5 may not be uncommon, but a 60 year one was.
Mathematically, life expectancy is the mean number of years of life remaining at a given age, assuming age-specific mortality rates remain at their most recently measured levels. It is denoted by {displaystyle e_{x}}, which means the mean number of subsequent years of life for someone now aged {displaystyle x}, according to a particular experience. , maximum lifespan, and life expectancy are not synonyms. Life expectancy is defined statistically as the mean number of years remaining for an individual or a group of people at a given age. Longevity refers to the characteristics of the relatively long life span of some members of a population. Maximum lifespan is the age at death for the longest-lived individual of a species. Moreover, because life expectancy is an average, a particular person may die many years before or many years after the “expected” survival. The term “” has a quite different meaning and is more related to longevity.
Life expectancy is also used in plant or animal ; (also known as ). The term life expectancy may also be used in the context of manufactured objects, but the related term is used for consumer products, and the terms “mean time to breakdown” (MTTB) and “” (MTBF) are used in engineering.
Throughout the HSBE I and II courses, you have explored the biological, psychological, and sociological aspects of different phases of the human life span. You have explored life-span development theories that help to explain human behavior. You also have considered how the social environment influences individuals and their behavior.Gathering facts about a client’s life span through the interview process is an important social work skill. This week, you practice this skill by interviewing an older adult using the questions in the Life Span Interview document available in this week’s resources.
For this week’s Assignment you transform your interview notes into a narrative—that is, a life story—of the older adult you interviewed. You interweave within this narrative an analysis of the life story by applying person and the environment concepts to your understanding and interpretation of that story.
Submit a 3- to 5-page paper in which you provide a narrative analysis of the Life Span Interview you completed.
The paper should:Provide a chronological history of the individual’s major life experiences.
Identify specific biological, psychological and sociological influences that shaped the individual’s experience.
Analyze the individual’s experiences by applying theory and concepts learned throughout both HBSE courses.
Provide your reflection of the experience, both in interviewing the individual and analyzing their narrative.
Explain what you learned and how you will apply this to future social work practice
