• Founder of Demography


  John Graunt
• Bills of Mortality


  Weekly recording of deaths in London
• Bills of mortality were the weekly mortality statistics in London, designed to monitor burials from 1592 to 1595 and then continuously from 1603
• John Graunt's analysis


  • Classified death rates according to causes of death, including overpopulation
  • Found male birth rate higher than female but offset by greater mortality rate for males, so population divided evenly between sexes
  • Invented the life table, which presented mortality in terms of survivorship and predicted percentage of persons that will live to each successive age and their life expectancy
• Demography


  The statistical study of HUMAN populations
• 2 Kinds of Demography

  • Formal Demography (Demography)
  • Social Demography (Population Studies)
• Formal Demography


  • Concerned with the precise mathematical and statistical measurement and recording of the three population processes: Mortality, Fertility, and Migration
  • Concerned with explaining the three population processes: Mortality, Fertility, and Migration using demographic data
• What Formal Demography studies


  • Population Size
  • Population Structure
  • Population Growth and Decline
  • Population Distribution
  • Population Characteristics/Composition
  • Population Processes
• De Facto Population


  Physical presence in a given territory at a given moment in time
• De Jure Population


  You will be counted to where you are permanently residing
• Population Pyramid


  A graphical illustration that shows the distribution of various age groups in a population
• The Philippines has the 8th largest population in Asia
• Metro Manila population is 15 million by day and 12 million by night
• Population Growth Rate


  The rate at which the number of individuals in a population increases in a given time period
• Types of Population Growth Rate

  • Positive Growth Rate (population increasing)
  • Negative Growth Rate (population decreasing)
  • Zero Growth Rate (same number at beginning and end)
• Fast Growth Rate


  The population is increasing at a rapid rate, often with ages 23 and below as the dominant population
• Slow Growth Rate


  The population is increasing, but in a slow manner, often with old populations and low birth rates
• Population Density


  A measurement of the number of people in an area, calculated by dividing the number of people by area
• Factors affecting Population Density

  • Sparsely Populated (few people)
  • Densely Populated (many people)
• Population Characteristics/Composition


  • Social Status (age, sex, religion, civil status, ethnicity, race)
  • Economic Status (education, occupation, income)
• Population Processes


  • Mortality (Death and Morbidity)
  • Fertility (Birth)
  • Migration (Mobility)
• Social Demography


  • Concerned with explaining a demographic phenomenon using other perspectives such as sociological, economic, or biological perspectives
• The Philippines has the highest unemployment rate among members of the Association of Southeast Asian Nations (ASEAN)
• The Philippines has 4,780 babies born daily, or about 199 babies born per hour or 3 babies per minute
• The objective of Formal Demography is to describe population processes (mortality, fertility, and migration) by measuring, and to explain them using demographic data
• The objective of Social Demography is to explain a demographic phenomenon using other data (aside from demographic data) such as sociological, economic, or biological data
