Final answer:
External factors such as ethnic violence, poverty, and drought can force people to migrate from rural areas to cities with high unemployment rates. Highly industrialized countries offer more economic opportunities compared to developing countries, attracting migrants. Social issues like unemployment, urban decay, and inadequate healthcare or education can also drive migration.
Step-by-step explanation:
External factors can significantly influence migration and employment opportunities. For example, in low-income countries, factors such as ethnic violence, poverty, and drought can force people to migrate from rural areas to cities where unemployment rates are already high.
On a global scale, highly industrialized countries offer more economic opportunities compared to developing countries, attracting migrants in search of better employment prospects.
Additionally, factors like social issues, including widespread unemployment, urban decay, and inadequacy of healthcare or education, can also contribute to migration patterns.
