Which of the following statements correctly synthesizes two migration scales?
A. A population census is only useful in identifying local migration trends.
B. Internal migration at the local level occurs less frequently than national external migration.
C. National economic push factors in developing countries can create global migration patterns.
C. National economic push factors in developing countries can create global migration patterns.
The correct statement that synthesizes two migration scales is option C: National economic push factors in developing countries can create global migration patterns.
To determine which statement correctly synthesizes two migration scales, we need to analyze each statement and understand the concept of migration scales.
Migration scales refer to the different levels or scopes at which migration occurs. There are three primary migration scales:
1. Internal migration: This refers to the movement of people within a country, typically from rural areas to urban areas or between different regions within the same country.
2. National external migration: This refers to migration between different countries, involving the movement of people across national borders.
3. Global migration: This encompasses migration at an international level, including the movement of people across continents and between different regions of the world.
Now let's review each statement:
A. A population census is only useful in identifying local migration trends.
This statement primarily focuses on local migration trends and implies that a population census has limited utility in understanding migration beyond the local level. However, it does not explicitly synthesize two migration scales, so this statement is unlikely to be the correct answer in this context.
B. Internal migration at the local level occurs less frequently than national external migration.
This statement compares internal migration at the local level with national external migration, suggesting that the latter occurs more frequently. It synthesizes two migration scales by highlighting the difference in occurrence between internal and external migration. Therefore, this statement may be a correct synthesis of migration scales.
C. National economic push factors in developing countries can create global migration patterns.
This statement connects national economic push factors in developing countries to the creation of global migration patterns. While it acknowledges the influence of national factors on global migration, it does not explicitly synthesize two migration scales. Therefore, this statement may not be the correct answer in this context.
Based on the definitions and the analysis provided, it appears that option B is the statement that correctly synthesizes two migration scales, as it compares internal migration at the local level with national external migration.
