Zorluk: OrtaPopulation Migration Causes and Effects

A demographic survey in a rural farming district reveals that ongoing land degradation has forced working-age adults to move to coastal cities for employment, leaving behind mostly children and elderly residents. Which of the following statements correctly identifies the type of migration factor involved and its demographic impact on the rural source region?

  1. Land degradation acts as an environmental push factor, leading to an increase in the dependency ratio of the rural source region.Cevap
  2. B
    Land degradation acts as an economic pull factor, causing an increase in the proportion of the economically active population in the rural source region.
  3. C
    Land degradation acts as an environmental push factor, causing a decrease in the overall dependency ratio because fewer people remain in the rural source region.
  4. D
    Land degradation acts as a pull factor that reorganizes the rural source region into a nucleated linear settlement pattern.

Cevap

Land degradation acts as an environmental push factor, leading to an increase in the dependency ratio of the rural source region.
Negative environmental conditions such as land degradation at the origin are classified as push factors because they drive residents away. When young, economically active adults relocate, the remaining rural population consists disproportionately of dependents (children and the elderly), which increases the dependency ratio of the source community.

Adım Adım Çözüm

1
Identify the migration force driving the movement
Land degradation is a negative condition at the place of origin, which constitutes a push factor.
Push factors are adverse conditions at the origin that compel people to leave, whereas pull factors are attractive conditions at the destination.
2
Analyze the demographic effect on the source region's age structure
The out-migration of working-age adults reduces the denominator (working population) relative to the numerator (dependents: children and elderly).
The dependency ratio is calculated as the non-working population divided by the working-age population multiplied by 100.
3
Synthesize the correct combined conclusion
The movement is driven by an environmental push factor and results in an elevated dependency ratio in the rural origin.
Matching both correct geographical classifications yields the true statement.
