Population and sustainable development
This document discusses population and sustainable development in the Philippines. It defines key demographic terms like population growth rate, population structure, and spatial distribution. The Philippines' population is characterized as expansive, with a very young age structure and high population density in some areas. The main determinants of population change are discussed as fertility, mortality, and migration. Rapid population growth is shown to strain economic development, education, employment, health services, and the ecosystem in the Philippines.

Population Growth Demography The scientific study of human populations, including size, composition, distribution, destiny, growth, related socio-economic characteristics and the causes and consequences of changes in population. Growth Rate Describes the rate at which population is increasing or decreasing; i.e. the surplus or deficit of births over deaths and net migration. Philippines’s population growth is 2.3 % annually.

Constructive Has a base that is narrower than the middle of the pyramid usually a result of a result of a recent rapid decline in fertility affecting the younger age groups Has a narrow base with approximately equal numbers in each sub sequent age group, tapering off the older ages and indicating a moderate proportion of children at a slow rate.

- 9. Philippine agestructure is very young: more than two out of every five persons are less than 15 years old. In 1983, about 14.7 million women in the Philippines have reached the child bearing age. The researchers believed that by the end of the 20th century, the number will grow up to 20 million. It only implies large fertility between that time and the year 2000.

Fertility the fist determinant of population change. (births) CBR (Crude Birth Rate) Is the number of births per 1,000 population in a given year, usually the estimated midyear population. TFR (Total Fertility Rate) Is the average number of children per woman.
- 11. 2. Mortality Thesecond determinant of population change. (death) Is the technical term for death. It is a component of population change and has a negative effect on population. CDR (Crude Death Rate) is the simplest measure of mortality rate which is the number of deaths per 1,000 population in a given year.
