TRENDS AND ISSUES

• A population is defined as a group of individuals of the same species living and interbreeding within a given area.
• The world economy is divided into three parts: developed, developing, and underdeveloped.
• Rapid population growth leads to environmental damage.
• Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.
• The difference between population and demography is that population is the people living within a political or geographical boundary while demography is the study of human populations, and how they change.
• Demographic Analysis focuses on this enduring collectivity, studying changes in its size, growth rates, and composition.
• Many of the indexes used in demography (life expectancy at birth, total fertility rate) translate aggregate-level processes into statements about the demographic circumstances faced by an average or randomly-chosen individual.
• Physical factors that affect population distribution include high population, low population, shape and height of land, resources, and climate.
• Human factors that affect population distribution include political, social, and economic factors.
• The major reason for population changes, whether in an individual country or for the whole world, is the change in birth and death rates.
• The Demographic Transition Model attempts to show how population changes as a country develops.
• In Stage 1, which applied to most of the world before the Industrial Revolution, both birth rates and death rates are high, resulting in a constant but fluctuating population.
• In Stage 2, the introduction of modern medicine lowers death rates, especially among children, while birth rates remain high, resulting in rapid population growth.
• In Stage 3, birth rates gradually decrease, usually as a result of improved economic conditions, an increase in women’s status, and access to contraception.
• In Stage 4, birth and death rates are both low, stabilizing the population.
• The median age in the Philippines is 25.7 years.
• The Philippines population is equivalent to 1.41% of the total world population.
• Consequences of Population Growth include Investment, Overuse of Resources, Urbanization, Per Capita Income, Standard of Living, Agricultural Development, Employment, Social Infrastructure, Labor Force, Capital Formation.
• 50% of the population in South-Eastern Asia is urban (334,418,881 people in 2019).
• External migration is moving to a different state, country, or continent.
• Human patterns of movement reflect the conditions of a changing world and impact the cultural landscapes of both the places people leave and the places they settle.
• Internal migration is moving within a state, country, or continent.
• Seasonal migration is moving with each season or in response to labor or climate conditions.
• The population density in the Philippines is 368 per Km2 (952 people per mi2).
• South-Eastern Asia ranks number 3 in Asia among subregions ranked by Population.
• The current population of South-Eastern Asia is 680M as of April 2022, based on the latest United Nations estimates.
• Emigration is leaving one country to move to another.
• South-Eastern Asia population is equivalent to 8.58% of the total world population.
• 47.5% of the population in the Philippines is urban (52,008,603 people in 2020).
• Push factors for migration include food shortage, war, flood.
• In order to study how the world population changes over time, it is useful to consider the rate of change rather than focusing only on the total population level.
• Human migration is the movement of people from one place in the world to another.
• The population density in South-Eastern Asia is 154 per Km2 (399 people per mi2).
• World population growth 1950-2050.
• Pull factors for migration include a nicer climate, job opportunities, better food supply.
• The Philippines ranks number 13 in the list of countries (and dependencies) by population.
• The median age in South-Eastern Asia is 30.2 years.
• The current population of the Philippines is 112,213,933 as of Today, April 6, 2022, based on Worldometer elaboration of the latest United Nations data.
• Developed countries tend to have stronger economies, higher levels of education, better healthcare, a higher proportion of working women, and a fertility rate hovering around two children per woman.
• The Philippines 2020 population is estimated at 109,581,078 people at midyear according to UN data.
