Growing Old, Growing Young: Demographic Challenges
Hussein A. Sayed
Growing Old, Growing Young: Demographic Challenges The main theme of the session is actually
emphasizing the demographic challenges facing nations and subpopulation as a result of their different level of progress within the demographic transition process.
The same conclusion was also confirmed by the papers presented, although limited to the Australian experience, but it can be also observed at various levels:
* Global / Regional * National * Sub-national
Growing Old, Growing Young: Demographic Challenges Besides their demographic implications, they will
have clear implications for the measurement of progress, assuming that already have a common consensus of what various stakeholders mean by progress?
The presentations and the position elaborated yesterday showed different views about what is meant by progress for different groups and organs depending on various factors including the level of those concerned, the context and the time factor.
Growing Old, Growing Young: Demographic Challenges
Major prevailing demographic challenges that need to be elaborated include:
The changing age structure of the population;
Global Ageing; Migration; and, Population characteritics.
Demographic Transition: The Changing Age Structure
Long-term changes in fertility and mortality resulted in fundamental population dynamics that was reflected on the age structure.
The speed and depth of such changes varies, across nations and subpopulations, depending on their place within the demographic transition process.
Such differences can be noticed for different regions and globally, as shown in Table 1, representing the expected average annual growth rates during the period 2005- 2050.

Demographic Transition: The Changing Age Structure Significantly low average annual rate of change
for the age group 0-14 years. With the exception of the least developing countries, the rate is very low and even negative for developed regions and parts of the less developed countries. This is mainly the result of continuous low birth rates.
Similar trend is noticed for the age group 15-59 years, although the differences between developed and developing countries is becoming more obvious.
Global Ageing
Population dynamics, accompanied by significant improvements in health and longevity among the elderly are leading to growing percentages of ageing populations and growing rates of old age dependency.
Table 2 show a different pathways to the changes in the age structure, leading to growing old and growing young populations at different parts of the world.
The prevalence of two population models is clearly seen, at the regional level, reflecting the varying impact of population dynamics (fertility and mortality).
The percentage of the population of age 60+ years amounted to 20% in the developed regions compared to only 11% in developing countries.
The trend is expected to continue manifesting in 2050 (32% compared to 20% respectively).
Significant differences are observed across regions, the percentage of population 60 years or over in Africa (2006) amount to 5 % compared to 21% for Europe and 17% for North America, confirming the prevalence of two models at various levels.

Global Ageing
The ageing process would continue globally, across regions and countries as can be seen from Table 2.
By 2050, the percentage 60 years and over is to reach 22% and such percentages would be doubled for almost all developing regions, but the gap between developed and developing countries would narrow.
Similar percentage for Europe and North America would reach 34 and 27 % respectively.
Global Ageing: Overall Impact
Successful ageing leading to maximizing desired outcomes, i.e. “ adding life to years, not years to life”.
AS stated by ageing experts, successful ageing is the confluence of three functions:
* Avoidance of disease and disability;
* High cognitive and maintain physical and mental functioning;
* Involvement in society and being active with life.
Global Ageing: Overall Impact
The aspirations of this growing group and their challenges need to reflected in measuring progress.
Various aspects of life for this group include: * Health transition, morbidity and disability; * Marital status changes & intergenerational
relationships; * Family structure and the changing norm of the
nuclear family; * Living arrangements; * Work participation; * Retirement and social security benefits.Table 3 presents some characteristics of this group.

Demographic Challenges: Migration
Migration trends, similarly affected the changes in the age structure;
Migration stocks from developing countries might benefit from the better conditions in the receiving countries, but the benefits for the former are affected by many factors;
Managed migration programs are based on circular migration, short-term movements and incentives for return back. This will affect population dynamics in different ways .
A new type of data collection mechanisms are required.
Demographic Challenges: Population Characteristics Human development aspects including
health, education and economic growth; Gender concerns, especially among
ageing population; Special groups needs and absorbing them
within the society ( disability and people with psychological disorder)
Level of HIV/AIDS epidemic and death, especially in some region such as Africa.
Demographic Challenges and Measuring Progress Measurement of progress that takes into
consideration such demographic challenges, would require:
* Identifying the aspirations and desirable outcomes for various groups and locations;
* A combination of aggregate and distributional measures to respond to the needs of various special groups and geographic locations;
* Improving the quality of primary data and widening the scope of measurements to take contextual aspects into consideration.
Demographic Challenges: Data Requirements Providing primary quality data for various defined
administrative level; Collect information to monitor the situation of
subpopulation groups, especially the ageing, to enable countries to develop better policies in that respect(such as the Health & retirement study of the USA) while at the same time develop systems to collect information on children;
Collect development information on international migration, especially that some countries are benefiting from this to help stem the decline of population size and working-age.
Measuring Progress
Measuring progress is a dynamic continuous process that depend on the perception of progress:
GDP considered a measure of progress in goods &services
HDI is mainly concerned with expanding abilities to make informed choices
Progress in that continuum should be concerned with capacity to achieve/realize informed choices.
