Individual Aging vs. Population AgingBy: Lemuel G. Salvana, RN MN

At the end of this lecture, the listener will

be able to;Define individual age in terms of:

Chronological Age

Physical Age

Functional Age

List Factors that affect individual aging

Define Population aging in contrast to individual aging

Describe the causes of population aging; and

Describe population aging using population pyramids and other graphs.

Individual Aging

Means growing older

1. Chronological Age

2. Physical Age

3. Functional Age

Population Aging

A condition that describes the state of a population.

Refers to the phenomenon where the proportion of older people to total population is increasing steadily so that a significant percentage now lives up to advanced old age.

A country is considered to be aging if the proportion of people aged 60 and over is at least 7 percent of the total.

Causes of Population Aging

Theory of Demographic Transition describes the growth of populations over a long period of time in three stages:1. The Pre-Transition stage

(high birth and death rates = zero growth)

2. Transition Stage

(decline in births and decline in deaths but not an equal pace)

3. Post-transition stage(very low growth because both birth and death rates are equally low)

Trends in Fertility

Trends in Mortality

POPULATION PYRAMID

Economic and Sociocultural Implications of Population Aging

Economic Implications

Fewer people to contribute in the “pay as you go system”

Increasing number of people who are no longer economically productive

In the Phils, SSS and GSIS are not automatically pegged to inflation rates.

Sociocultural Implications

Developed Countries….

Developing Countries (eg Philippines)

Activity:In a sheet of paper, draw yourself and briefly describe the kind of life you would want when you reach 70 years of age…

Assignment:Research on the latest Population Pyramid of the Philippines and compare it with the population pyramid of any developed country.
