5. To discuss different ways on how students can curb population growth in the Philippines.
A. Philippine Demographics
The Philippines has one of the fastest growing populations in the world. Based from estimates, it is the 12th most populated nation in the world, making 1.34% of the total global population. According to the National Statistics Office, the estimated population in the Philippines as of July 2011 is 101, 833, 938; a noticeable increase from the 2010 Philippine 2Population which is 99, 900, 177. Tomas Osias, Executive Director of the Commission on Population said that by the year 2014, the
population might boom to approximately 101.2 million. Philippines, with these growing population, developed a 1.903% growth rate as of the 2011 EST. 61.1% of Filipinos in the country are 15-64 years old, 31, 103, 967 are males while there are 31, 097, 203 females in this census. 82.9% of the Filipino people are Catholics while the most dominant Ethnic group is the Tagalog people with 28.1%.
B. Factors that affect Population Growth
Population growth is defined by three growth factors (death rate, birthrate and immigration/emigration rate) and two limiting factors (density dependent and density independent limitation). The birthrate or the fertility rate is the number of childbirths per 1, 000 people per year (in estimation review points). Birth rate is also coined as the natality of the population. The birth rate is calculated using live birth counts from a universal system of registered births. The death rate or the mortality rate (in general, or due to a specific cause) in population, scale to the size of population, per unit time. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus, a mortality rate of 9.5 in a population of
100,000 would mean 950 deaths per year in that entire population, or 0.95% out of the total. The birth rate for the Philippines is 25.34 births/1,000 populations (2011 EST.) while there is a 5.02 deaths/1,000 population (July 2011 est.) death rate.
The immigration/emigration rate (derived for the Latin: migratio) is the rate of foreigners passing and coming out of a country for the purpose of permanent residence. Immigration is made for many reasons, including economic, political, family re-unification, natural disaster, poverty or the wish to change one's surroundings voluntarily.
The density-dependent limitation factor decrease population growth through environmental stress including limitations in food, predation and other factors like diseases. Density-independent limitation includes food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes. The former are often biotic factors while the latter are abiotic factors.
