 True
 False

8) The socalled saturation effect of population growth can be applied to
 alogistic growth model
 barithmetic growth model
 cgeometric growth model
 dexponential growth model

 aaritmetic growth model
 blogistic model
 cgeometric growth model
 dexponential growth model

12) The simple growth model approach is preferred to the components method of projection because of its ability to determine not only likely future population size but also age and sex distributions.
 True
 False

13) Some of the most advanced approaches to forecasting have been developed in the business fields of marketing and finance.
 True
 False

14) Exponential growth assumes a continual increase in the rate of growth between two dates.
 True
 False

15) When faced with the problem of anticipating the size and/or structure of a population at a date for which information is unavailable, population scientists begin with the premise that change can only occur through the effects of fertility, mortality, and migration.
 True
 False

16) Forecasts and projections, including matrixbased projections, both attempt to assess the size and/or composition of future populations. However, they employ dissimilar methods.
 True
 False

17) The linear model assumes that
 athe population growth rate is constant between intervals
 bpopulation growth follows “S” curve
 cpopulation growth is followed by sharp population decline
 dpopulation growth is curvilinear during the given interval(s)

18) The lack of certainty about future trends makes it necessary for demographers to take informed guesses about what is to be expected.
 True
 False

19) With the declines in birth rates in Europe, several countries
 aare at or below ZPG
 bhave seen rapid increases in mortality rates
 cbirth rates began to increase by 2010
 done of the above

20) One of the differences between population estimation and projection is that
 aestimation is used to obtain longterm predictions of population
 bprojection is used to obtain longterm predictions of population
 cestimation is used to predict the changes in fertility and mortality
 dprojection is used to predict the changes in fertility and mortality

21) The Pareto’s curve is a mathematical model that refers to
 aan agesex distribution
 ba measurement tool to predict urban growth
 ca principle of economic saturation
 dan enumeration used to indicate an intercensus year population size

22) William Ascher (1978) has pointed out that the substantive knowledge required to make valid assumptions in demographic applications is now well developed.
 True
 False

23) The simple growth model approach can be used to produce a set of projections based on one date, one growth rate, and three or four different equations.
 True
 False

24) Among the following models, which one would produce the highest estimation?

 barithmetic growth model
 cgeometric growth model
 dexponential growth model

25) Which of the following methods is the most efficient tool in making projections?
 acomponents method
 bextrapolation
 cmatrixbased method
 dsimple growth models

26) The logistic model assumes that
 apopulation grows more rapidly than the food to sustain its members
 babsolute growth remain nonconstant over the period under observation
 cgrowth rates remain nonconstant over the period under observation
 dB and C, above

27) The process of making estimations or projections from a census date by using the simple growth models is called
 aextrapolation
 binference
 cforecast
 dinterpolation

28) The simple growth model can readily be applied to projection without the need for a series of high, medium, and low estimates.
 True
 False

29) Once the idea of having rates vary over a projection period is considered, the possibilities are virtually unlimited, as we attempt to develop projection models that more faithfully capture the way in which real populations change.
 True
 False

30) Qualitative forecasting methods are dependent on numeric time series data.
 True
 False
