migration and its Effects on population

Migration refers to the movement of people from one place to another, typically with the intention of settling in the new location. It can occur within a country (internal migration) or between countries (international migration). Migration has significant effects on both the population of the place of origin and the destination.

Effects Of Migration on the Population of the place of Origin:

  1. Demographic changes: Migration can lead to changes in the age structure and sex ratio of the population left behind. For example, if young adults migrate in large numbers, it can result in an ageing population and a decrease in the working-age population.
  2. Economic impact: Migration can have both positive and negative economic effects on the place of origin. On one hand, remittances sent back by migrants can contribute to the local economy, stimulate consumption, and improve living standards. On the other hand, the loss of skilled workers can negatively impact productivity and economic development.
  3. Social and cultural changes: Migration can affect the social fabric and cultural dynamics of the place of origin. It can lead to changes in social norms, values, and traditions. It may also disrupt community structures and relationships, as well as contribute to the loss of cultural heritage.

Effects on the population of the destination:

  1. Demographic changes: Migration can alter the demographic composition of the destination. It can result in population growth, particularly in urban areas, leading to increased diversity and multiculturalism. Immigrants often have higher fertility rates, which can contribute to population growth in the long term.
  2. Economic impact: Migration can bring economic benefits to the destination, including filling labor market gaps, addressing skill shortages, and promoting entrepreneurship. Immigrants can contribute to economic growth, innovation, and tax revenues. However, there may be short-term challenges in terms of labor market competition and pressure on public services.
  3. Cultural enrichment: Migration can enrich the cultural landscape of the destination by introducing new languages, cuisines, traditions, and perspectives. It can promote cultural diversity, intercultural dialogue, and the exchange of ideas, leading to social and cultural innovation.

It’s important to note that the effects of migration can vary depending on various factors such as the scale and nature of migration, policies governing migration, social integration measures, and the specific contexts of the origin and destination regions.

Types of Migration and how it affects population

Migration is defined as the movement of people from one geographical area to another, involving permanent or temporary residence or settlement.

In migration, the region where people are leaving is called the source region while the region where people are entering is called the receiving or destination region.

Types of migration

There are two major types of migration. These are emigration and immigration.

  • Emigration: This is the type of migration in which people leave their own countries, i.e. movement out of a country.
  • Immigration: This is the type of migrations in which people enter into another country, i.e. movement into another country
  • .
Forms of migration

Migration from one place to another takes different forms. These include:

  • Rural-urban migration: This is the movement of people from rural areas, villages, to urban

centres like Ibadan.

  • Rural-rural migrations: This is the movement of people from one rural to another rural area.
  • Urban-rural migrations: This is the movement of people from one urban centre to rural areas.

  • Urban-urban movement: This is the movement of people from one urban centre (town or city) to another.

  • International migration: This is the movement of people from one country to another.
  • Seasonal migration: This is the movement of people from one place to another during a particular season, summer holidays abroad.
Factors affecting migration

The following factors account for dying migrations of people from one area to another.

  • Natural disasters: The occurrence of natural disasters like floods, famines droughts and earthquakes, could make people migrate out of place.
  • Physical conditions: The physical conditions of a place such as the climate, souls relief may also be responsible for the people, especially when such  conditions are unfavourable
  • Insecurity: Fear of insecurity arising from war, political instability, etc. could make people migrate.
  • Differences in economic opportunities: As a result of these, people tend to migrate to where there are more economic opportunities like jobs and business transactions.
  • Changes in status: Changes in status, e.g. high level of education and wealth, could make people migrate, e.g. from rural-urban centres.
  • Differences in social amenities: Owing to differences in the availability of water, roads and electricity, people tend to move to where these amenities are present

Advantage of migration

  • It reduces population pressure on agricultural land at the source region.
  • It reduces population pressure on social amenities in the source region.
  • It supplies migrant labour at the receiving legion.
  • It ensures the flow of capital to the living region.
  • It leads to the development of social amenities at the receiving region,

  • It boosts markets at the receiving region,
  • It promotes cultural integration, e.g. inter­marriage at the receiving region.

Disadvantages of migration
  • It breeds social vices like crime and armed robbery at the receiving region.
  • It increases the high cost of living at the receiving region.
  • It leads to pressure on social amenities at me receiving region.
  • It leads to the loss of able-bodied men and arid youth at the source region,
  • It leads to congestion in housing and transportation at the receiving region,
  • It leads to a decline in production at the source region.
  • It leads to unemployment at the receiving region.
  • It also leads to cultural disintegration at the destination region.

One of the major forms of migration that tend to create problems in all developing countries is of rural-urban migration.

Since we recognize that this form of migration is a major problem, solutions have to be provided in order to prevent the occurrence of overpopulation in the receiving regions. The solutions to the problems of rural-urban migration include:

  •  Provision of social amenities: The provision of social amenities such as water, electricity, cinemas, roads and telephones in rural areas will go a long way in reducing the rate at which youth move to urban areas.
  •  Transformation of traditional agriculture to modern agriculture: This will enable the youth to engage in agriculture as the system will make farming interesting.

  •  Establishment of industries: The establishment of industries, projects and businesses that will absorb the rural working population and reverse labour movement will go a long way in reducing rural-urban drift.

  •  Establishment of educational institutions: The establishment of colleges and other institutions of higher learning in rural areas will also help to reduce movement to urban centres.

  •  Establishment of corporate branches: Government departments, business firms and financial institutions should be encouraged to establish their branches in rural areas.

Provision of recreation facilities: If recreational facilities like stadia, swimming pools, cinema houses and amusement parks, are matters available in rural areas, 1 reduce the propensity of our youth to move to urban areas.
