Nepal can be divided into 75 districts, 14 zones and three ecological regions such as mountain, hills and Terai. Population growth rate differs according to the development regions. The given table shows the population distribution in mountainous, hilly and Terai region of Nepal.
If we study the above mentioned table carefully, we find that the mountainous region is most sparsely populated compared to the hills and the Terai. There is a due to the availability of fertile soil and couple of other facilities in this region. Therefore, the Terai region has the highest population of all the geographical regions.
Looking at the population growth rate of different geographical regions, the growth rate in the mountainous and hilly regions is less and even decreasing whereas in the Terai region, the average annual population growth rate is very high. The population growth rate for the Terai in 2001 was 2.62 which is higher than the national population growth rate of 2.24%. Thus, the Terai has now become over-crowded.
The means and resources available in the Terai regions are not actually sufficient to bear of load of such population pressure. Therefore, there is a need to control of tendency of people migrating to the Terai region by having equal development to all areas of the country.
