  2. Definition
    of static and dynamic demography
    • Static demography: studies population in a determined moment

    • Dynamic demography: studies population along time (changes due to people coming
    • in and out of the group)
  3. Demography
    • UNO: science
    • that studies human population (size, structure, evolution) from a quantitaive

    • demography provides data about population used for:
    • - rates and other health indexes
    • - epidemiological studies
    • - public health management and planning
  5. Static
    demography sources:
    •  census, poll, approximative methods, active
    • population survey.
  6.  Census concept
    • census is the main data source for static demography group of activities directed to gather, analyse and issue demographic, cultural, economical, social data of all inhabitants of the country in a determined

    is a static demography source

    • definition:

    • about population is based on estimations. they are approximative data
  14.  Usefulness of active population survey

    • important information in intercensus periods
  15. Basic shapes
    of population pyramids:
    • pagoda
    • (progressive), bell (stabilized), money-box (regressive)
  16. Sundbarg
    index: what is it useful for?
    • classify population in 3 age groups:
    • from 0-14
    • from 15-50 (principal interval, 100%)
    • more than 50 years
    • dont differenciate men and women
