Explain the purpose of studying population according to age, sex, geography and occupational distribution
Answers
Answer:
Population geography is a division of human geography. It is the study of the ways in which spatial variations in the distribution, composition, migration, and growth of populations are related to the nature of places. Population geography involves demography in a geographical perspective.[a] It focuses on the characteristics of population distributions that change in a spatial context. This often involves factors such as where populations are found and how the size and composition of these populations is regulated by the demographic processes of fertility, mortality, and migration. Contributions to population geography because geographical epistemological related to environment, place and space have been developed at various times. Related disciplines include geography, demography, sociology, and economics.
Since its inception, population geography has taken at least three distinct but related forms, the most recent of which appears increasingly integrated with human geography in general. The earliest and most enduring form of population geography emerged in the 1950s, as part of spatial science. Pioneered by Glenn, Wilbur Zeal in sky, William A. V. Clark, and others in the United States, as well as Jacqueline Pierre George in France, it focused on the systematic study of the distribution of population as a whole and the spatial variation in population characteristics such as fertility and mortality.[1] Population geography defined itself as the systematic study of:
the simple description of the location of population numbers and characteristics
the explanation of the spatial configuration of these numbers and characteristics
the geographic analysis of population phenomena (the interrelations among real differences in population with those in all or certain other elements within the geographic study area).
Accordingly, it categorized populations as groups synonymous with political jurisdictions representing gender, religion, age, disability, generation, sexuality, and race, variables which go beyond the vital statistics of births, deaths, and marriages. Given the rapidly growing global population as well as the baby boom in affluent countries such as the United States, these geographers studied the relation between demographic growth, displacement, and access to resources at an international scale.
Examples can be shown through population density maps. A few types of maps that show the spatial layout of population are , I so line, and dot maps.
