Population and sustainable development

  1. 1. Population and Sustainable Development Lesson 1
  2. 2. Overview
  3. 3.  Philippine Development vision can be warped by a family size too large to sustain.  Concern for rapid population growth must be solved fast.
  4. 4. Meaning of Population
  5. 5. Components of Population  A. 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.
  6. 6. B. Population Structure
  7. 7. Expansive  Broad based indicating high proportion of children and a rapid population growth. 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. Stationary
  8. 8. Philippines ----Expansive Germany-------Stationary Singapore-----Constructive
  9. 9.  Philippine age structure 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.
  10. 10. C. Spatial Distribution  Population Density  number of population per square meter of land area  Provides a means of spatial distribution of population  1. 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. 11. 2. Mortality  The second 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.
  12. 12. 3. Migration  Basically from rural to Urban.  It is not universal.  Relatively permanent movement of persons over a significant distance.  Reasons  Employment  Pursuit of higher education  Expectation of better housing and other social services  Political instability  Natural calamities  Population pressure on agricultural lands
  13. 13. Consequences of Rapid Population Growth  Economic Development  Education  Employment  Health and Other Social Services  Ecosystem
  14. 14. Economic Development  1994-5.1 GNP growth rate  1995-5.2 GNP growth rate  Forty Percent of Filipinos still live below poverty line.
  15. 15. Education  1994 Philippine Human Development Report-literacy rate is 93.54%.  Lack of Classrooms, materials and Teachers.
  16. 16. Employment  800 k applicants a year, only 200k are accepted.  1994 figure-9.6 % employment rate, 2.2% underemployment rate.  12.5% underemployment in urban areas, 6.6% in rural areas.
  17. 17. Health and Other Social Services  As population grows, the maintenance of existing health and social services becomes increasingly difficult.
