Thot Paper Argument: Internal migration to Metro Manila poses threats both to the population’s health and to the environment as well. It needs to be addressed not only by improving industrial and environmental conditions of metro manila alone but also the conditions of the rural areas so locals will not consider migrating to urban communities as their only option for progress. Outline: Definition of internal migration Migration has been practiced by humans ever since they have acquired the ability to walk on across the globe, with the Homo erectus species being the first one to accomplish this task. This prompted the spread of culture, information and the growth of civilizations and communities. In the present era, with states and countries established, migration has evolved into different types. One of which is internal migration, the type of migration in which a person relocates to another area that is still within the state of his original residence (National Geographic). Internal migration in the Philippines According to APCAD (2018), statistics show a dense percentage of population in internal migrants varying in long distance movers and short distance movers. The former are those who move in to a different province while the latter are those that only change the city they reside in. Factors of internal migration to manila Philippine Statistics Authority considers economic, social, political and cultural factors in the growing number of internal migrants. It was learned in reports that 2.9 million Filipinos have changed residency from 2005 to 2010. Moreover, it is observed that the urban population continuously rises in significant rates, and in 2010, 41.9 million, 45.4% of the country’s population that year, reside in the cities. It is expected, as the Philippines continues to be one of the fastest urbanizing country in the Asia-Pacific region (APCAD, 2018), and with the current government’s “Build, Build, Program”, the engine of industrialization and urbanization is hastened. Statistics also show that the CALABARZON region leads in the reception of long distance movers at 27.7% and Metro Manila follows at 19.7%. The two regions also dominate the Gross Domestic Product ranking among the regions of the Philippines with NCR at the top (36%) followed by CALABARZON’s 17% (PSA, 2018). Business establishments continue to rise within the two regions, and it prompts Filipinos in the rural communities to seek job opportunities and later on residence in the metro.
