Explain why different parts of Southeast Asia vary so much in regard to both population density and population growth?

What will be an ideal response?


The differences in population density are a reflection of settlement patterns and physical geography. Population densities are highest in those fertile river valleys that are dominated by rice cultivation. The rugged, mountainous terrains are characterized by lower densities of population; these areas are characterized by swidden agriculture—although recent population encroachments and deforestation have significantly altered this practice. Population growth is in part affected by the age-structure of the country and also by governmental policies that have either encouraged or discouraged population growth.
