According to Zelinsky's model of migration, which demographic stage leads to increased emigration pressure to more developed countries?

In Zelinsky's model of migration, as countries progress through demographic stages, migration patterns evolve significantly. Stages 2 and 3 are particularly characterized by increased emigration pressure to more developed countries.

During Stage 2, countries often experience a high birth rate and declining death rates due to medical advancements and improved living conditions. This leads to a substantial population growth that can outstrip available resources and job opportunities, prompting individuals to migrate to more developed areas in search of better economic prospects and improved living standards.

As countries transition into Stage 3, birth rates start to decline, but population growth can still be significant. In this stage, the economy may begin shifting toward industrialization, which can create new job opportunities; however, the rapid population increase often continues to outpace these opportunities. This creates further emigration pressure as individuals seek greater stability and prosperity in developed nations.

In contrast, Stages 1 and 2 are more focused on internal migration and do not exhibit the same patterns of emigration to developed countries. Stage 4 and 5 typically involve low birth and death rates, where migration pressures might shift towards internal migration for job opportunities rather than an outmigration trend. Thus, it is Stages 2 and 3 that align
