ThesisStatement:Population and migration are the primary concerns of world`sgeography.
Populationand migration is the fifth chapterin the book, ‘Introduction to Geography People, Places, andEnvironment (5th Edition).` The chapter starts by describing theprocess of the population growth and the distribution of people inthe world, which has more than 6.4 billion people. It explains howpeople live, what they do, and the way they move from one place toanother. This chapter discusses the critical forces that affect deathrates, birth rates, and migration.
Thesize of a population may change because of three main reasons birthof people, death, or migration. The demographic measures includebirth rates, death rates, total fertility, rate of natural increase,and the infant mortality rate (Dahlman,Renwick & Bergman, 2011).Population pyramids tend to indicate gender and age subgroups. Theage structure facilitates the determination of death and birth rates,as well as the ratio of different workers to that of those who areeither too old or too young to be productive.
Themale to female ratio is usually higher when they are young than whenthey are elderly this indicates the real status of men in comparisonto women. According to Dahlman (2011), many countries do desire lowerbirth rates, and there are many methods to achieve it. Stimulatingeconomic development, industrialization, and urbanization assuggested by the demographic transition model are some of the waystowards achieving lower birth rates. Family planning is anothersimple method, which involves advocacy through public policy and massmedia. Countries that have low birth rates enhance proper policiesfor future economic growth.
Inmost cases, a high rate of deaths is attributed to infectiousdiseases many interventions are being adopted to decrease this rate.These interventions include improving water supplies and vaccinations(Dahlmanet al., 2011).The chapter concludes by discussing the process of migration. Themigration concept entails international movements and it tends toface many challenges and opportunities in the current world.
