Population Distribution and Structure in Nigeria Explained Clearly

37

Population distribution and structure in a broader view is what we are lookíng at but before we expand, let’s look at the lesson objectives.

Lesson Objectives

By the end of the lesson, students should be able to:

1. Identify areas of high and low population density in Nigeria.
2. Explain reasons for the high and low population density in population distribution.

Areas of High Population Density in Nigeria (Population Distribution)

In population distribution, there are areas with a large number of people living per square kilometer.
Examples include:

1. Lagos State: Lagos State is the most densely populated area in Nigeria. It is the commercial and industrial centre of the country and was once the federal capital. Millions of people from all parts of Nigeria and even neighboring countries move to Lagos in search of jobs, business opportunities, and better living conditions. The state has numerous industries, good road networks, seaports, airports, and other social amenities such as schools and hospitals. The high level of urbanisation and availability of basic services make Lagos a major attraction for migrants, leading to overcrowding in many parts of the city.
2. Anambra State: Anambra State, in southeastern Nigeria, has one of the highest population densities in the country. The area has fertile land that supports intensive farming, especially yam, cassava, and vegetables. It is also known for its high level of commerce and industry, with towns like Onitsha and Nnewi serving as major trading and manufacturing centers. Good road networks, educational institutions, and access to markets have encouraged people to settle there. Many families live close together due to limited land space, resulting in a very dense population in urban and rural areas alike.
3. Imo State: Imo State, also in the southeastern region, is another area with a high population density. The people of Imo are mostly farmers, traders, and civil servants. The land is fertile and suitable for growing a variety of crops. In addition, the state has many educational institutions and public offices that provide employment opportunities. The cultural attachment to family land and the tradition of living close to relatives have led to the clustering of people in villages and towns. Over the years, these factors have made Imo one of the most crowded states in Nigeria.
4. Ogun State: Ogun State, located in the southwestern part of Nigeria, has a high population density due to its closeness to Lagos. Many people live in Ogun but work in Lagos, because housing is cheaper and transport links between the two states are good. Ogun also has several industries, including cement factories and manufacturing plants, especially around Abeokuta, Sagamu, and Ota. The state’s fertile land and educational institutions attract both workers and students. Its strategic location between Lagos and other southwestern states makes it a fast-growing and densely populated area.
5. Kano State: Kano State, located in the northern part of Nigeria, is also highly populated. It is the largest city in Northern Nigeria and a major centre for trade, agriculture, and manufacturing. The state’s history as a key commercial hub dates back to the trans-Saharan trade period. Its markets, like the famous Kurmi Market, attract traders from within and outside Nigeria. Kano has fertile land for farming, and the presence of industries, schools, and religious institutions draws many people to live and work there. The combination of economic and cultural activities has contributed to its dense population.

Reasons for High Population Density in These Areas

1. Industrialisation: One major reason for high population density in certain areas of Nigeria is the presence of industries. Industrial areas such as Lagos, Ogun, and Kano provide many job opportunities in factories, offices, and businesses. People move to these places to find work and improve their living standards. Industries also attract other services like banking, transport, and housing, which create even more employment. As a result, the population continues to grow because people prefer to live close to where they can easily find work and earn a steady income.
2. Fertile Soil: Fertile soil encourages people to settle and farm successfully. Areas like Anambra and Imo States have rich, productive soil suitable for growing crops such as yam, cassava, and maize. When the land produces enough food and income, farmers are less likely to migrate elsewhere. Fertile regions also attract traders, food processors, and transporters, all of whom come to benefit from agricultural activities. Over time, the abundance of fertile land leads to the growth of towns and villages, resulting in high population density.
3. Good transportation: Areas with well-developed transportation systems — such as roads, railways, airports, and seaports — attract large populations. For example, Lagos has a major seaport and airport that connect Nigeria to other parts of the world, while Kano is a key transport hub in the north. Good transport makes it easy to move goods and people, encourages trade, and helps businesses grow. Because people can travel easily for work or trade, they tend to live in places with better transport links, increasing the population density.
4. Availability of social amenities: Social amenities like schools, hospitals, electricity, pipe-borne water, and entertainment centers make life more comfortable. Cities such as Lagos and Owerri (Imo State) have better infrastructure and public services than rural areas. This attracts people seeking a higher standard of living. Students move to such places for education, while workers and families settle there to enjoy modern facilities. The concentration of these amenities causes more people to migrate to these cities, making them densely populated.
5. Commercial activities: Trade and commerce also play a big role in attracting people. Towns like Onitsha (Anambra) and Kano are famous trading centers where goods from all over the country and beyond are bought and sold. Traders, transporters, and suppliers all move to these commercial centers to do business. As business expands, more people move in to benefit from the economic opportunities, build houses, and start families. This constant inflow of people makes such areas heavily populated.
6. Historical factors: Some areas in Nigeria have been densely populated for a long time because they were early centers of civilisation, trade, or traditional power. For instance, Kano and Ibadan were important ancient cities long before Nigeria’s independence. People have lived and traded there for centuries, leading to the natural growth of the population. In addition, cultural and family ties encourage people to remain close to their ancestral homes rather than moving away, increasing population density in those traditional regions.

Areas of Low Population Density in Nigeria (Population Distribution)

Also, in population distribution, there are areas with few people living per square kilometer include:

1. Borno State: Borno State, located in the northeastern part of Nigeria, is one of the areas with low population density. The region experiences very hot and dry climatic conditions for most of the year due to its location in the semi-arid zone. Rainfall is low and irregular, making farming difficult. In addition, frequent insecurity and insurgency have forced many people to migrate to safer areas. The combination of harsh weather, poor soil, and insecurity discourages people from settling permanently in the state.
2. Yobe State: Yobe State, also in the northeastern region, has similar features to Borno. The land is generally dry, sandy, and not very fertile, which limits agricultural activities. Water sources are scarce, and the desert is gradually encroaching on farmland. The area also suffers from insecurity and limited infrastructure such as roads, schools, and hospitals. These conditions make life difficult, leading to low population density as people move to more developed and fertile regions.
3. Adamawa State: Adamawa State lies along Nigeria’s eastern border with Cameroon. Although parts of the state have fertile land, the mountainous terrain and uneven distribution of rainfall make large-scale settlement difficult in some areas. Some parts of the state are prone to flooding during the rainy season, while others remain dry for long periods. Limited industries and employment opportunities cause many young people to migrate to urban centers, leading to a relatively low population density.
4. Taraba State: Taraba State is located in the middle belt of Nigeria and is characterised by many hills, mountains, and rivers. While the scenery is beautiful, the rugged terrain and thick vegetation make transportation and communication difficult. Many communities are isolated and lack basic infrastructure such as good roads, schools, and healthcare centers. The combination of poor accessibility and limited economic activities discourages large settlements, resulting in a low population density.
5. Cross River (northern parts): The northern part of Cross River State has thick tropical rainforests and hilly terrain. The dense vegetation makes it difficult to build roads, houses, or large farms. Many parts of the area are rural and lack modern amenities, which discourages people from settling there in large numbers. Although the soil is fertile, farming is mostly at a subsistence level due to poor access to markets. In population distribution, these factors contribute to the area’s sparse population.
6. Niger State: Niger State, located in north-central Nigeria, is vast but sparsely populated. Much of the land is covered by forests, rivers, and hills, including the Kainji Lake and large expanses of uninhabited land. Farming is the main occupation, but settlements are scattered, and infrastructure development is low. Because of the large land area and limited urban centers, people are spread thinly across the state, making the population density low.
7. Plateau State: Plateau State is known for its beautiful highlands and cooler climate, but its mountainous nature limits large-scale settlement. Many parts of the state are difficult to reach due to poor roads and steep terrain. Farming is possible on the plateaus, but the land available for building and expansion is limited. As a result, the population is concentrated in a few urban areas like Jos, while most other parts remain sparsely populated.

Reasons for Low Population Density in Those Areas

There are reasons for low population distribution in the areas where there are low population density. They are:

1. Unfavorable climate: One of the main reasons for low population density in some parts of Nigeria is the harsh and unfavourable climate. Areas such as Borno and Yobe States experience extremely hot and dry weather conditions with very little rainfall. This makes farming and other forms of livelihood difficult. Water is scarce, and the land is often dry and sandy. Because of these uncomfortable living conditions, many people move away to cooler and more fertile regions, leading to sparse population in such areas.
2. Poor soil fertility: Soil fertility greatly affects where people choose to live. In many northern parts of Nigeria, the soil is poor, dry, and sandy, making it difficult to grow crops. Even when it rains, the soil cannot hold enough moisture for plants to survive. As a result, farming, which is the main occupation of many Nigerians, is not productive in these areas. Since agriculture cannot support large populations, fewer people choose to settle there, causing low population density.
3. Lack of industries and jobs: Industrialisation and employment attract people to live in an area. However, in many sparsely populated regions of Nigeria, there are very few industries or businesses. Most people rely on small-scale farming, which does not provide enough income. The absence of factories, markets, and offices means there are limited job opportunities. Young people often migrate to cities like Lagos, Kano, or Port Harcourt in search of work, leaving behind a small and scattered population in rural areas.
4. Poor infrastructure: Another important reason for low population density is the lack of basic facilities such as roads, electricity, schools, and hospitals. In many rural or mountainous parts of Nigeria, roads are bad or non-existent, making movement and trade difficult. Without electricity, good schools, and hospitals, people find life uncomfortable and may relocate to urban centers where such amenities are available. Areas with poor infrastructure therefore remain sparsely populated.
5. Insecurity: Insecurity has also played a major role in reducing population density in certain parts of Nigeria, especially in the North-East. Frequent attacks, insurgency, and communal clashes have forced people to flee their homes to safer places. Farmers are often afraid to go to their farms, and businesses close down due to fear of violence. As people leave these unsafe regions, population density decreases, and the once lively areas become empty or deserted.
6. Presence of thick forests or mountains: Some regions of Nigeria, especially in the middle and southern parts, have thick forests, hills, and mountains that make settlement difficult. For example, parts of Taraba, Plateau, and Cross River States have rough landscapes that are hard to build on or farm. Thick vegetation makes it costly to clear land for housing or roads. Because of this, few people choose to live there, resulting in sparse settlements and low population density.
