  1. “Global Population”ICSEClass 10

  2. Global Population • A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. On the basis of age distribution, population is classified into three types i.e., expanding population, stable population and declining population. • Expanding population includes high proportion of infants and children (0 -14 years age group). In stable population, birth and death rates are almost equal. Declining population includes comparatively more old aged persons. • Population density (n) is the total number of individuals in a per unit area in a given time . • Birth rate is the number of children born per 1000 living person in the population, per year. Death rate is the number of deaths per 1000 living person in the population, per year. Immigration can be defined as the addition of number of individuals of same species from outside into existing population while emigration is the departure of individuals of same species, to outside from existing population.
