Q. Which one among the following South Asian countries has the highest population density? (UPSC Prelims 2009)
Answer: Nepal
Notes: Nepal has the highest population density among the listed South Asian countries. Its mountainous terrain, particularly in the Kathmandu Valley and southern plains, causes a concentrated population in limited habitable areas. In contrast, India and Pakistan have larger geographical regions that distribute their populations more evenly, while Sri Lanka's overall population density remains lower than Nepal's when considering total population relative to livable land.
