Question

which factor is the primary reason urbanization occurs?
○ migration
○ desire for blended culture
○ increased birth rate
○ scarce resources

Explanation:

Urbanization is defined as the shift of population from rural to urban areas. Migration, specifically rural-to-urban migration, is the core driver as it directly moves people into cities, causing urban growth. Other options are secondary or not primary: blended culture is a byproduct, birth rates affect population size but not the urban shift itself, and scarce resources may push migration but are not the direct primary cause.

Answer:

migration
