In this section, the concept of human resources is presented as a crucial component for development, with emphasis on their unequal distribution and the factors contributing to population density and changes. Population distribution varies globally with over 90% of the population occupying only 30% of the land. Factors affecting this distribution include topography, climate, soil fertility, water availability, and economic opportunities. Variances in population densities are further explored through population pyramids, illustrating how birth and death rates affect population compositions and future labor forces. This understanding is vital for devising policies to harness human potential effectively.
