Research Reports - Population and Development Interrelationships
Our views of the real world can be summarized in terms of this population and development interaction model. While this may not be the only way to do it, this model is useful in the sense that: (1) it shows the relationship and population and development factors, and (2) it distinguishes between processes and outcomes.
with the population processes - fertility, mortality and migration.
These processes lead to outcomes - population size; age / sex structure
or the distribution of the population by age and sex; and spatial
distribution or the distribution of population in various regions or
various areas. These population outcomes affect in many different ways
the various development processes, such as consumption of goods and
services ( e.g., food, health, education and housing ), savings and
investment behavior, public expenditure patterns, utilization of human,
physical and natural resources, etc.
For example, if government provides for primary schooling, and the school-age population increases, then government might have to spend more to accommodate this larger population of school-age children. In a very simple sense, that is how population outcomes affect development processes.
Sometimes the relationship can be a bit more complex than that. Other processes include utilization of resources - utilization of land that affects the productivity of land as well as the environment; utilization or non-utilization of labor, leading to levels of employment, unemployment and underemployment; and utilization of capital and technology. All these processes, in turn, lead to development outcomes which, more or less, indicate the extent to which we are achieving our development objectives.
outcomes could be expressed in terms of income or its distribution,
levels of employment, educational, health and nutritional status and
even environmental quality, which might be affected by either
extensive, excessive or improper use of land and other natural
resources. These socioeconomic outcomes, in turn, also affect the very
population processes of fertility, mortality and migration that we
started out with
In general, there is an interaction between population factors on one hand, and development factors on the other, in terms of the interaction of their processes and outcomes.
