Content of Population Geography .

INTRODUCTION:-  In''geography of population'' G.T. Trewartha says, ‘population serves as the point of reference from which all other geographic elements are observed and from which they all singly and collectively derive significance and meaning.

 "The central theme of the science of population geography is the areal differentiation ….’’ On the other hand, some geographers like John In Clarke (1965), Wilbur Zelinsky (1996), J Beaujeu Garnier, Robert Woods(1979), M.S Sidhu(1980) gave their own definitions of population geography from various perspectives. 

1. Distribution of the population related to space means their characteristics. 

Example-size of the population, the distance between the settlements, settlement patterns in 

continent and sub-continent region, inter-regional distribution & whole distribution of population 

approach to ecumenic and non-ecumenic.  

                                             

 2. Population density, type of the population density…. 

❑ Physiological density 

❑ Nutrition density 

❑ Arithmetic density 

❑ Agricultural density 

❑ Economic density 

3. Population migration, international migration, type of migration, a consequence of population migration, cause of migration develops and developing country or region. 

                Migration laws Raven stein’s model, Gravity model, Lee’s model, Lewis-Fei-Ranis model. 

➢ Rate of migration:- 

• Gross migration • Net migration • Balance migration • Effective migration 

      

4. Population growth measurement, birth rate death rate measurement, indicators of population growth (climate, food habitat) and their impact, population theory, population. 

      

5. Ethnic composition (identify the people category by resumed similarity, common language, history, society, culture, nation or social treatment with their residing area), religious composition, linguistic composition, age-sex composition, occupational structure, economic composition, dependency ratio, workforce employment status, income classifications, poverty distribution.  

6. Literacy and illiteracy & their difference, indicators, world pattern of population, quality of people, the process of improvement of quality of people. 

7. Population resource ratio, improvement of population growth and resource, optimum population, low population, overpopulation, population policy (china-One Child Policy), etc. 

8. Population of rural and urban and their structure and pattern and their differences, urbanization processes, the trend of urbanization. 

9. population trend of geographical point of view in global or regional position, world population projection, life expectancy, population control by economic, social, political, etc. 

     

Population geography involves demography from a geographical perspective. Population geography definition itself as the systematic study of: -

(a) The simple description of the location of population number and characteristics. 

(b) The explanations of the spatial configuration of these numbers and characteristics. 

(c) The geographic analysis of population phenomena (the inter-relation among real differences in population with those in all or certain other elements within the geographic study area). 

            Demographic phenomena (natality, mortality, growth rates, etc.) through both space and time. Zelinsky classified the phenomena to be covered by a population geographer into three broad categories:-

(a) Essentially biological; 

(b) Economic, social, cultural in causation; and  

(c) Those constituting the elements of dynamic.
