A population pyramid, also known as an age-sex pyramid, is a graphical representation that illustrates the distribution of a population by age groups and sex.
Key features and functions:
- Structure: It typically consists of two back-to-back bar graphs, with the population's age groups displayed on the vertical axis and the number or percentage of males and females in each age group on the horizontal axis.
-
Shape: The shape of a population pyramid provides insights into a population's demographic history and future trends. For example:
- A broad base indicates a high birth rate.
- A narrow top suggests a low life expectancy.
- Irregularities can reflect past events such as wars, famines, or epidemics.
- Analysis: Population pyramids are used by demographers, sociologists, and policymakers to analyze population trends, make projections, and plan for future needs in areas such as healthcare, education, and employment.

The population situation in Nepal is characterized by a complex interplay of factors including population size, growth rate, distribution, and demographic composition. Here's a breakdown:
Current Population Size
- As of recent estimates, Nepal's population is around 30 million. Worldometers estimates about 30.6 million as of 2024.
Population Growth Rate
- Nepal's population growth rate has been declining over the past few decades.
- The annual growth rate is now below 1%. The World Bank indicates a growth rate of approximately 0.84% in 2022.
Population Distribution
- Nepal's population distribution is uneven, with a higher concentration in the Kathmandu Valley and the Terai region (plains) due to better economic opportunities and agricultural productivity.
- Many rural, hilly, and mountainous regions are sparsely populated.
Demographic Composition
- Nepal has a relatively young population, but the median age is increasing, indicating a gradual aging of the population.
- Fertility rates have declined significantly over the years, contributing to the slowing population growth. The total fertility rate is around 2.1 births per woman.
Challenges and Opportunities
- Challenges: Rapid urbanization, pressure on resources and infrastructure, unemployment, and the need for improved healthcare and education services.
- Opportunities: A demographic dividend (a larger working-age population relative to dependents) if investments are made in education, skills development, and job creation.
