Population: A Lively Introduction Conclusion The study of population dynamics involves the interplay among the three sources of population change: fertility, mortality, and migration. These variables determine the most basic characteristics of a population, as well as its demographic future. The effects of demographic variables extend far beyond the growth or decline in the number of people. As demographer Samuel Preston has so eloquently written: "The study of population offers something for everyone: the daily dramas of sex and death, politics and war; the interlacings of individuals in all their collectivities; the confrontations of nature and civilization, [of] statistics and diaries, [of] self-interest and altruism." | |
