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.
