Which of the following is the shape of the age-sex pyramid of Nigeria?...
The age-sex structure of a population refers to the number of females and males in different age groups. A population pyramid is used to show the age-sex structure of the population. The age-sex pyramid of Nigeria is a triangular shaped pyramid with a wide base and is typical of less developed countries. These have larger populations in lower age groups due to high birth rates. If we construct the pyramids for Bangladesh and Mexico, it would look the same.

Age-Sex Pyramid of Nigeria
The shape of the age-sex pyramid of a population is a graphical representation of the age and sex distribution of that population. In the case of Nigeria, the shape of the age-sex pyramid is triangular.
Explanation
- Triangular Shape: The age-sex pyramid of Nigeria is triangular, with a wide base representing the younger population and narrowing towards the top, which represents the older population. This shape is characteristic of a population with a high fertility rate and a large proportion of young people.
- Youthful Population: Nigeria has a high birth rate and a large youth population, which contributes to the pyramid's triangular shape. The country has a median age of around 18 years, indicating a significant proportion of young people.
- Population Growth: The triangular shape of the age-sex pyramid suggests that Nigeria has a rapidly growing population, with a high number of children and young adults. This can have implications for various aspects of society, such as healthcare, education, and employment.
- Challenges and Opportunities: While a youthful population can offer opportunities for economic growth and innovation, it also poses challenges in terms of providing adequate resources and services for the younger generation. Nigeria's demographic profile highlights the need for policies and programs that address the needs of its young population.
- Comparison to Other Shapes: The triangular shape of Nigeria's age-sex pyramid contrasts with other shapes such as bell-shaped (developed countries with stable populations) or tomb-shaped (aging populations with low birth rates). Nigeria's pyramid reflects its current demographic situation and the potential for future population growth.
