•Climate:

Climate is as important as terrain in influencing population. Of all the climatic factors, twin elements of rainfall and temperature play the most important role in determining the population of an area. Man cannot go beyond the limits set by climate.

Extremes of climate discourage the concentration of population. Such climates include the too cold climate of Himalayas, and the too hot and dry climate of the Thar Desert. A moderate climate, on the other hand, is favourable for population.

▪️Relief features also play an important role in influencing population distribution. The influence of altitude has already been noted. Among the other aspects of relief features which affect human habitation are general topography, slope and aspect. The main concentrations of human population are confined to the areas marked with flat topography. Rugged and undulating topog­raphy restricts the condensation of human population in any area.

Abrupt changes in the density of population can be seen on the world map of population distribution where plains meet mountain ranges. Rising Himalayas, thus, mark the northern limit of dense population in the Ganga plain. Similarly, the Deccan plateaus with rugged and undulating topography appear distinct from the plains in respect of population concentration. In the mountainous areas valleys provide suitable locations for human settlements. Likewise, sun-facing slopes provide favourable locations for the emergence and growth of settlements.
