Which of the following statements correctly synthesizes two migration scales?

National economic push factors in developing countries can create global migration patterns.
Trends of globalization can create global migration patterns such as migration corridors.
A population census is only useful in identifying local migration trends.
Internal migration at the local level occurs less frequently than national external migration.

Trends of globalization can create global migration patterns such as migration corridors.

The statement that correctly synthesizes two migration scales is:

Trends of globalization can create global migration patterns such as migration corridors.

To determine which of the following statements correctly synthesizes two migration scales, we need to review each statement and understand the relationship between the migration scales mentioned.

1. National economic push factors in developing countries can create global migration patterns.
This statement suggests that push factors at the national level in developing countries can lead to global migration patterns. It highlights the connection between national-level factors influencing migration and the global migratory outcomes.

2. Trends of globalization can create global migration patterns such as migration corridors.
This statement suggests that the broader trends of globalization can shape global migration patterns, including the creation of migration corridors. It emphasizes the impact of globalization on migration patterns at the global scale.

3. A population census is only useful in identifying local migration trends.
This statement focuses on the usefulness of a population census in identifying local migration trends, suggesting that it may not be effective for identifying migration patterns at larger scales.

4. Internal migration at the local level occurs less frequently than national external migration.
This statement contrasts internal migration at the local level with national external migration, suggesting that internal migration occurs less frequently than migration at the national scale.

Based on the information provided, the statement that correctly synthesizes two migration scales is:
"National economic push factors in developing countries can create global migration patterns."
This statement combines the influence of national-level push factors on migration with the resulting global migration patterns.
