Final answer:
Urban migration in the Philippines is mainly directed towards the National Capital Region (NCR), which includes Manila, the political capital of the country. This region attracts migrants looking for better opportunities, but rapid urbanization often results in the development of informal settlements.
Step-by-step explanation:
Urban migration in the Philippines, particularly towards the National Capital Region (NCR), is significant due to the concentration of opportunities and governmental activity in the area. The NCR hosts the political capital of the country, which is Manila, not the majority of agricultural lands, highest mountain peaks, or the largest freshwater lakes. This urban region has become a beacon for migrants seeking better living standards and employment, typically leading to rapid urbanization and the development of informal settlements or slums due to infrastructural and service demands exceeding supply.
