  1. POPULATION

  2. Counting people—rationale and how • Guides our policy (what services to provide in terms quantity) (scarcity/surplus) • Helps us plan programs ( whom and where the services be offered) • Data can be used also by private institutions, corporations, and companies

  3. Example: Planning to put a school (Education Manager) • You need to know the population of potential students because: • 1. You will know the number of classrooms you might want to build. • 2. You will know how many teachers you will hire to achieve good student-teacher ratio.

  4. Example: Road Construction (Engineer) • Quantity of people that will likely use. • The number of cars that will likely pass.

  5. For Medical Doctors:

  6. For Students in Marketing • You are tasked to come up with a social marketing plan for carbonated soft drinks. • Your task then is to identify the areas in the Philippines which have higher rates of carbonated soft drinks use. • YAFS 4 can offer you this data, particularly in the context of youth in the Philippines.

  7. For Students in Sociology/Social Sciences • You are tasked to come up with a plan in order to curb population. • Your task then is to identify the areas in the Philippines with high population growth rate.

  8. Investor from Japan, to put up an institution for the elderly

  9. You are a hotel manager and your boss asked you to come up with a promo or campaign to increase hotel room occupancy. Which month should you have the promo?

  10. Total population De facto (in practice) versus de jure (in law) Census (characteristics) —universality (not sampling) and simultaneity

  11. Population and housing census has five main objectives • Population and households data • Demographic information used for calculating population estimates. • Information for government ministries and local authorities for planning and budgeting purposes. • Socio-economic information on large sample of people and even those considered unique.

  12. Counting Population • It also helps us understand changes in family structure and composition. • Who and how many are the household family members • Composition (nuclear or extended) • Absentee • Which area is considered populated • How many are married, widowed, separated?

  13. Change in population size is relative Population may vary in different areas (regions, provinces, municipalities, cities)

  14. Change in population size is relative Size may increase, decrease, or remain the same

  15. Change in population size is relative Growth may be fast, moderate or slow

  16. Calculate: • Compute for the projected population of the Philippines for year 2011 if you have the following given: • 2010 Population: 92,337,852 • Growth Rate: 2% • Answer:

  17. When conducting Census • It is important that the respondents should be the household head. • Accurate enumeration. Reporting inaccurate information may impact program intervention. • INSERT VIDEO

  18. Change in population composition and distribution What types of people are counted, and how many of each type are there? People are typed according to their characteristics: physiological (e.g., sex); social (e.g., religion), economic (e.g., work status); vital events (e.g., number of children), and household/family (e.g., number of household members), ethnicity

  19. Population composition and distribution in a population pyramid (Philippines) ( a relatively young population)

  20. Spatial distribution of population How many, and what types of people are counted in a given geographic area? Population density: number of people per unit area (Philippines: 302per sq. km.)

  21. Components of change in population size Births (B) or fertility Deaths (D) or mortality Immigration (I) Emigration (E) Example: She emigrated from Barangay Ngalangala and immigrated to Barangay Ngolongolo.

  22. Population composition and distribution in a population pyramid (Japan)

  23. Demographic Dividend Low fertility rate Low mortality rate Low dependency ratio Large working population More revenues Less Expenses Therefore, there will be an increase in economic growth, provided that there are sound economic policies and investments made

  24. POPULATION Demographic Measures

  25. Basic Demographic Rates Ratio: relative size of two numbers. Population ratios are used to describe the degree of balance between two elements of the population. Rule If below 10,000 population you use 100 (k) If more than 10,000 use 1,000 (k) If more than 100,000 use 10,000 (k) In our class we use 100 (k) for dependency and sex ratio and all others are 1000 (k) Always round off your answers.

  26. Dependency Ratio • This ratio quantifies the number of persons in a population who are not economically active for every 100 economically active persons in that population.

  27. Dependency Ratio • This ratio quantifies the number of persons in a population who are not economically active for every 100 economically active persons in that population. • Tells us how many of the population are 14 years old and below (0-14 years old) and how many are 65 and above. • The higher the dependency ratio is, the greater the burden in supporting the elderly and the infants/and children below 14. • Implication: higher dependency ratio calls for more jobs to help defray social cost.

  28. Formula + Population of age under 14 Population of age over 65 - Population of age under 14 + Population of age over 65 Total Population X 100

  29. Formula + Population of______ Population of ____ - Population of age _____ + Population of age over _____ Total Population X 100

  30. Example: Community Pasaway has 45,025 children under age 14 and 7,500 persons age 65 and over. The total population is 80,000. Note: Express answer without decimal point. Rule in rounding off numbers applies. For example: 3.3 just indicate 3 3.9 indicate 5

  31. Formula + Population of age under 14 45,025 Population of age over 65 7,500 - Population of age under 14 + Population of age over 65 52,525 Total Population 80,000 X 100 =192

  32. Therefore, there are 191 persons in the population of Community Pasaway who are dependent on 100 economically active persons.

  33. Example: • Banana Republic has a population of 95,000. It has a population of 48,000 children under age of 14 and 12,324 age 65 and over.

  34. Answer • The dependency ratio is:  173.9=174 • There are 174 non economically active persons in 100 economically active persons.

  35. Sex Ratio • Sex ratio=number of men divided by the number of women x K (100)

  36. Why computer for sex ratio? • Provides us a benchmark regarding the quantity that should be afforded to women and men. • Equity of distribution of resources • We need to look at sex ratio to signal us when to intervene should we experience “marriage squeeze”

  37. Consequence of imbalance sex ratio • Marriage squeeze • Shortage of women leaves fewer brides available for the large number of prospective grooms.

  38. Sex ratio= number of men __________________ number of women x K (100)

  39. Sex ratio= number of ________ __________________ number of ________ x K (100)

  40. Example (45,000/44,000) x 100 = 102.3 or 102

  41. Sex Ratio • EXAMPLE: District “Makabagbag Damdamin” has 3456 male and 2543 female population. • Compute for the ratio: (3456/2543) * 100= Answer?

  42. ANSWER • Answer: 136
