Sex Ratio
The statistical indicator showing the number of females per 1,000 males in a given population, which helps assess gender balance in a country.
Population Pyramid
A specialized graphical bar chart that illustrates the age and sex structure of a country's population, helping determine the proportion of youth, working-age adults, and senior citizens.

Frequently Asked Questions
Why is the population density very low in the Amazon river basin?
The Amazon river basin has dense forests, a hot and humid equatorial climate, heavy rainfall, and rugged terrain, which make human settlement and transportation very difficult.
How do we read a population pyramid?
A population pyramid shows age groups on the vertical axis (with youth at the bottom and elderly at the top) and percentage of population on the horizontal axis, split between males on the left and females on the right.
Which part of India has a very high population density and why?
The Northern Indian Plains (like Uttar Pradesh and Bihar) have a very high population density due to flat fertile land, perennial rivers, favorable climate, and well-developed agriculture.
