Questions: Migration: Push-Pull Theory and Patterns

Question 1

Research consistently finds that residents of the poorest villages in low-income countries migrate internationally at *lower* rates than residents of somewhat wealthier villages in the same country. Which concept best explains this counterintuitive pattern?

• A. Residents of the poorest villages have fewer push factors because absolute deprivation reduces the desire to migrate
• B. International migration requires resources — money, credentials, social connections — to overcome costs and border barriers, pricing out the very poorest
• C. Ravenstein's laws predict that rural populations are less mobile than urban ones regardless of income
• D. Pull factors in destination countries are weaker for migrants from the poorest villages

Answer: (B)

The push-pull model would predict that the most extreme poverty produces the strongest push factors and thus the most migration. But this ignores intervening obstacles: international migration is expensive and requires capital, legal documents, and information that the very poorest lack. The relationship between poverty and migration is an inverted U — moderate poverty increases migration; extreme poverty actually suppresses it because the cost barrier is insurmountable. This is one of the push-pull model's key empirical failures.

Question 2

A migration stream from a Oaxacan village to a particular neighborhood in Los Angeles has persisted for 40 years, even as wages in both locations have converged. Which concept best explains the stream's persistence?

• A. Push factors in Oaxaca remain as strong as they were 40 years ago
• B. Ravenstein's counter-stream law produces a return flow that keeps the original stream active
• C. Migrant networks built by early migrants lower information and settlement costs for subsequent migrants, making movement self-perpetuating
• D. Intervening obstacles between Mexico and the US have decreased over time, increasing all migration flows

Answer: (C)

Chain migration (or migrant network theory) explains why migration streams persist long after original push-pull differentials have changed. Early migrants provide later migrants with housing, job leads, and local knowledge — social capital that dramatically lowers the cost and risk of moving. These networks are spatially concentrated (linking specific origin communities to specific destination neighborhoods) and are reproduced across generations. The migration stream becomes partially self-sustaining, independent of current economic differentials.

Question 3

According to Ravenstein's laws, most long-distance migrants travel directly from their rural origin to a distant major city in a single move.

• T. True
• F. False

Answer: False

Ravenstein observed *stepwise migration*: migrants tend to move in stages, first to a nearby town, then possibly to a larger city, rather than jumping directly to the most distant optimal destination. This pattern reflects the role of cost and information in migration decisions — each step is more manageable than a single large leap, and earlier moves provide the resources and knowledge needed for subsequent ones. Stouffer's intervening opportunity theory formalizes this: migrants stop at the closest destination that satisfies their needs.

Question 4

A person fleeing both active gang violence and chronic unemployment in their home country may simultaneously qualify as both an economic migrant and a refugee under international law.

• T. True
• F. False

Answer: False

Under the 1951 Refugee Convention, refugee status requires persecution on specific grounds (race, religion, nationality, political opinion, or social group) — not economic hardship or generalized violence. A person fleeing gang violence faces legal ambiguity: the violence is coercive (refugee-like) but may not meet the Convention's persecution standard, and the economic dimension is explicitly excluded from refugee protection. The legal categories are mutually exclusive in formal law, even though the empirical reality is mixed-motive migration. This is analytically important: the legal distinction shapes which protections and rights are available.

Question 5

Why does the push-pull framework predict that extreme poverty should produce high emigration, yet empirically the very poorest populations often have LOW international migration rates? What does this gap reveal about a key limitation of the push-pull model?

Model answer: The push-pull model treats migration as a rational response to conditions at origin and destination — extreme poverty should be a strong push factor, driving high emigration. But the model ignores that migration is itself costly and requires resources. Crossing international borders demands money for transport, legal fees, and initial settlement; credentials or networks to find work; and information about the destination. The very poorest lack all of these, making international migration practically impossible regardless of how strong the push factors are. This reveals that the push-pull model omits intervening obstacles — the filters between motivation and movement — which determine who among motivated migrants can actually move.

This gap between push-pull predictions and observed patterns motivated Stouffer's intervening opportunity theory and subsequent work on migrant networks and migration infrastructure. The upshot is that migration is not simply a function of conditions at origin and destination; it also depends on the resources, networks, and structural conditions that enable movement. The poorest individuals often 'aspire but cannot migrate,' a pattern that has significant implications for development policy and remittance flows.
