Answer:
The answer is below
Step-by-step explanation:
As of 2011, the population density of Nepal can be divided into three, Ecological zones which are mainly are mountain region, hilly region, and Terai region.
Between 1991, 2001, and 2011, using 10 years intervals, the Mountain region has a population density of 28, 33, and 34 respectively.
The Hilly region on the other hand has 137,167, and 186 respectively between 1991, 2001, 2011.
At the same time, the Terai region has between these three major years a population density of 254, 330, 392 respectively.
This implies that there has been an increase in population density of each region, even though some are more than the others particularly due to the terrain of each region.
