Study Notes
Population and Demography
- Population refers to a group of similar species living in the same time and place, occupying a certain geographic area, drawing substance from their habitat, and interacting with one another.
- Demography is the study of statistics such as births, deaths, income, or the incidence of disease, which illustrate changes in the structure of human populations.
- Demographers gather data about population size, distribution, composition, and change to describe populations.
Sources of Demographic Data
- Population Census: a population count conducted by government offices (NSO).
- Vital registration statistics system: birth, death, marriage, and divorce registrations.
- Sample or Special Surveys: surveys of households.
- Demographic data gathered and processed by government agencies.
Importance of Demography
- Understanding population trends and patterns helps address social, economic, and environmental issues.
Population Size and Distribution
- The current global human population is approximately 8.1 billion.
- The Philippines has a population of 117,337,368 as of 2023, with a yearly change of 1.54%, ranking 13th in the list of countries by population.
- Factors affecting population size include natality (birth rate), mortality (death rate), and migration.
Migration
- Migration refers to the transfer of individuals from one place to another.
- Push factors: economic (lack of job opportunities), social (inequality and discrimination), political (conflict and climate change), and environmental (natural disasters).
- Pull factors: economic (better job opportunities), social (social freedom and better quality of life), political (favorable and safer stability), and environmental (safety and stability).
Population Density and Distribution
- Population density: the number of persons living per square kilometer.
- Population distribution: the arrangement of individuals within a particular space, which can be random, uniform, or clumped.
Population Growth and Overpopulation
- Population growth: the increase of population, leading to issues like poverty, energy crisis, environmental degradation, criminality, housing problems, and inequality.
- Overpopulation: a scenario in which the population of a living species exceeds the carrying capacity of its ecological niche, leading to intensified problems.
- Effects of overpopulation: resource depletion, environmental degradation, social unrest, and decreased quality of life.
