 aaritmetic growth model
 blogistic model
 cgeometric growth model
 dexponential growth model

8) 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

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

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

13) 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)

14) Determining the likelihood that a particular outcome will occur is not within our capabilities, although it is usually safe to assume that current patterns will prevail until tomorrow, next month, or perhaps next year.
 True
 False

15) The difference between the simple growth models and the components method is that
 acomponents method takes sexage structure into consideration
 bsimple growth models take sexage structure into consideration

 False

18) Among the following models, which one would produce the highest estimation?
 alinear growth model
 barithmetic growth model
 cgeometric growth model
 dexponential growth model

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

20) Which of the following methods does not include populations over age 65?
 acomponents
 bcomponents II
 cadministrative records
 dcohort survival

21) 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

22) The administrative records method is no longer used by the Census Bureau to estimate the sizes of state, county, and subcounty (e.g., urban) populations.
 True
 False

23) Matrixbased methods can be used for any kind of projection, but they are computationally most efficient when projecting large populations over long periods with the use of computer programs.
 True
 False

24) The cohort survival method of estimation is more precise than the simple growth models because in the place of crude rates it employs agespecific measures, in a manner similar to life table analysis.
 True
 False

25) The assumption of a closed population applies to situations in which inmigration is
 afar greater than outmigration
 bequal to outmigration
 cfar less than outmigration
 dis unrelated to migration

26) 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
