  1. Demographic Transition

    The historical Shift of birth and death rates from high to low levels in a population. The decline of mortality usually precedes the decline in fertility, thus resulting in rapid population growth during the transition period.

  2. Millennium Development Goals

     

    MDG 1. Eradicate extreme poverty and hunger.

    MDG 2.  Achieve universal primary education.

    MDG 3. Promote gender equality and empower women.

    MDG 4. Reduce child mortality.

    MDG 5. Improve maternal health.

    MDG 6. Combat HIV/AIDS, malaria and other diseases.

    MDG 7. Ensure enviromental sustainability.

    MDG 8. Develop a global partnership for development

     

  3. How Population Grows ?

    World                                          B - D in a year per 1000 Population

                                                       Suppose 40 - 10=3.0 percent growth                                                       rate per annum

    Country:                                      B - D + Im - Em
     
    Province or District within
    each country:                             B - D - Im - Em + In - Out
     
    Urban Area within each

    country:                                       B - D + Im - Em + In - Out + Expansion


    Suppose the population grows at 3 percent per annum, what does it mean ?

    It means the population would double in 23 years, How?

    The formula is very simple:    Just divide 70 years by the rate of growth: 70 / 3 = 23 years

    It may be called the Law of Seventy.

    Note:
                   B     =    Births              D    =      Deaths
                   Im    =    Immigration     Em   =      Emigration

     

  4. Singulate Mean Age at Marriage

    The singulate mean age at marriage is the average length of single life expressed in years among those who marry before age 50.

     

  5. Zero Population Growth

    A population in equilibrium, with a growth rate of zero, achieved when births plus immigration equal deaths plus emigration.

     

  6. Stable Population

    A population with an unchanging rate of growth and an unchanging age composition, because of age-specific birth and death rates having remained constant over a sufficiently long period of time.

     

  7. Population Optimum

    The ideal number of people that can be sustained in a given area, in contrast to overpopulation and under population.

     

  8. Population Momentum

    The tendency for population growth to continue beyond the time that replacement level fertility had been achieved because of a relatively high concentration of people in the childbearing years.

     

  9. Net Reproduction Rate

    The average number of daughters that would be born to a woman (of group of women) of she passed through her lifetime from birth conforming to the age-specific fertility and mortality rates of a given year. This rate is similar to the gross reproduction rate, but takes into account that some women will die before completing their childbearing years. An NRR of 1.00 means each generation of mothers is having exactly enough daughters to replace itself in the population.

     

  10. Gross Reproduction Rate

    The average number of daughters that would be born alive to a women (or group of women) during her lifetime if she passed through her childbearing years conforming to the age-specific fertility rates of a given year.

     

  11. Doubling Time

    The number of years required for a population of an area to double its present size, given the current rate of population growth.

     

  12. Amenorrhea

    Amenorrhea, is the absence of a menstrual period in a woman of reproductive age. Physiological states of amenorrhea are seen during pregnancy and lactation (breastfeeding), the latter also forming the basis of a form of contraception known as the lactational amenorrhea method. Outside of the reproductive years there is absence of menses during childhood and after menopause.

     

  13. Population Pyramid

    Population Pyramid, also called age-sex pyramid and age structure diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which normally forms the shape of a pyramid.

     

  14. Polygyny

    Polygyny is a form of marriage in which a man has two or more wives at the same time.  It is distinguished from a relationship where a man who has a sexual partner outside marriage, such as a concubine, casual sexual partner, paramour, or other culturally recognized secondary partner. Polygyny is the most common form of polygamy.

     

  15. Growth Rate

    The rate at which a population is increasing (or decreasing) in a given year due to natural increase and net migration, expressed as a percentage of the base population.

     

  16. Infant Mortality Rate

    The number of deaths to infants under one year of age in a given year per 1,000 live births in that year.

     

  17. Maternal Mortality Rate

    The number of deaths to women due to pregnancy and childbirth complications per 100,000 live births in a given year.

     

  18. Total Fertility Rate (TFR)

    The average number of children that would be born alive to a woman (or group of women) during her lifetime if she were to pass through her childbearing years conforming to the age-specific fertility rates of a given year. See also gross reproduction rate and net reproduction rate.

     

  19. Fecundity

    The physiological capacity of a woman, man, or couple to produce a live child.
