This encompasses bulk of the peninsular block of India, excluding the plateaus of Tamil Nadu and western Karnataka. It includes south and southeast Rajasthan, lying east of Aravallis. Leaving a number of pockets cited in the previous category, majority of Madhya Pradesh falls in this zone of reasonable density of population. It also encompasses plateau of Western Orissa and Telangana in Andhra Pradesh, and some portions of eastern slopes of Sahyadri in Maharashtra.
The western half of this region is distinguished by low rainfall and black soils of irregular depth, intruded by rocky outcrops. The eastern half is more gravelly and surging and is covered with red soil, pretty thin in depth. In both these portions the topography is bouldery and soils are thin and far from prolific. Therefore, the density of population is determined by low to temperate rains, a rocky personality of the topography and presence of soil, largely in shallow pockets.
