WebApr 1, 2024 · Distribution Of Population. India’s present population makes up 17% of the world’s population. Additionally, these individuals are dispersed unevenly across our country’s 3.28 million square kilometers of land. With 166 million inhabitants overall, Uttar Pradesh has the highest density of population in India, according to the 2001 Census. WebIn random dispersion, the position of each individual is independent of the others, and spacing is unpredictable. Random dispersion occurs in the absence of strong attraction or repulsion among individuals in a population, or when key physical or chemical factors are relatively homogeneously distributed.
