| Term | Definition |
|---|---|
| Arithmetic density | the total population number divided by the land area of the country |
| Agricultural Density | the total number of farmers compared to the amount of land used to grow crops |
| Physiological Density | the total number of people per unit of arable land |
| Population density | the total amount of people living in a certain area of land |
| Human Migration | when people decide to move from one place to another to live there, usually permanently or for a short time |
| Emigration | exiting your own country to live in another country |
| Guest workers | someone who moves to another country temporarily because that country needs more workers |
| Immigration | people moving into a new country to live their permanently |
| Carrying Capacity | the maximum number of living things that an environment can sustain without running out of resources |
| Total Fertility Rate | average amount of kids a woman is expected to have during her lifetime |
| Doubling Time | how long it takes for a population to double twice it’s size- rule of 70 (dividing 70 by annual growth rate) |
| Refugee | a person that's forced to leave their home and go to another country in order to survive war, violence, or even natural disasters. |
| Internally displaced persons | a person who is forced to leave their home for safety, but stay within their countries borders instead of crossing into another country. |
| Mortality Rate | the total number of deaths in a population during a certain period of time and usually shown as the amount of deaths per 1,000 people in a year |
| Rate of Natural Increase/Natural Increase Rate | the rate at which a population is growing or shrinking only based on the number of births and deaths, not including migration. |
| Asylum seekers | someone who's left their home country to another hoping for safety and protection from internal problems back home- (not officially a refugee until their request is approved) |
| Push Factor | reasons that make people want to leave their country |
| Pull Factor | positive attractions that make people want to go to a new place/country |
| Forced Migration | when people leave their homes and move to another country because they have no real choice |
| Voluntary Migration | when people voluntarily leave their home because they want more opportunities for a better life |
| Intervening Opportunity | when something good pops up along the way of migration which causes someone to settle there instead of the place they were originally planning |
| Intervening Obstacle | something that either stops a person from reaching their planned destination, or makes it harder for them to |
| Chain Migration | when people from the same place follow each other and move to a new location one after another |
| Step Migration | when people reach their final destination in smaller moves rather than all at once |
| Pro-Natalist Policies | when a government encourages people to have more children because the population is decreasing and there may not be enough young workers to keep the economy strong. |
| Anti-Nationalist Policies | When a government tries to reduce the number of births in a country mainly because its growing too fast and using up resources more than expected |
| (live births / population) * 1000 | Crude Birth Rate |
| (deaths / population) * 1000 | Crude Death Rate |
| (# of children born/ # women aged 15-45) | Total Fertility Rate |
| The percentage of how much a population grows each year, excluding any migrants- (BR-DR)/10 | Rate of Natural Increase (RNI) |
| the amount of time it take for a population to double in size- 70 / RNI | Doubling Time |
| (immigrants - emigrants) / (population / 1,000) | Net Migration Rate (NMR) |
| (BR-DR + NMR) / 10 | Demographic Equation |
| Intraregional migration | When someone moves within a certain region of a country |
| Interregional migration | relating to or occurring between different regions. |
| Repatriate | Someone who is sent or chooses to go back to their home country after living somewhere else. |
| Eastern Asia (China), South Asia (India), Southeast Asia (Indonesia), Western Europe | Identify the FOUR highest population concentrations in order |
| Transhumance | Seasonal movement of someone and their livestock, usually from lowlands in the winter and highlands in the summer |
| Demographic Momentum | even if the fertility rate declines, the population can still grow for a while because there are already many young people alive to have children. |
| Dependency ratio | (# of people aged 0-14) + (# of people aged 65+)/ (# of people aged 15 to 64) * 100 |
| Ecumene | Active areas of the world where people actually permanently live |
| S curve (carrying capacity) | After rapid population growth, it will die down when it reaches the carrying capacity. Represents how instead of population growing forever, it can stabilize due to limited resources, food supply, and less birth rates. |
| J curve (malthusian theory) | represents exceeding population growth compared to food production which grows at a steady rate |
| Industrial and Scientific Revolution | Thomas Malthus theory and the TWO reasons why it never occurred |
| contractive pop. pyramid | Has a narrow base and is more wide in the higher ages. Birth rates way lower than the 2.1 ideal and an aging population that out paces the birth rate, leading to a declining population |
| Stationary population pyramid | Ss fairly even up and down the pyramid- rectangular. The birth rates and death rates are low and almost aligned making it stable |
| Expansive population pyramid | Very wide base and narrow at the top. Birth and death rates are extremely high making the life expectancy very low and fast population growth (DTM stages 1-2) |
| When the population is stable because the birth rates and death rates are equal (not including migration) | Zero Population Growth (ZPG) |
| Mostly Western and Northern European countries in 1840-1910 (Ireland, Britain, and Germany) In 1840, the Irish Potato famine occured | Wave One: Phase One- US immigration |
| In 1930’s, more transitions to Southern and Eastern Europe, recognizing what's about to happen (war) | Wave One: Phase Two- US immigration |
| After WWII, 1950- Asians and Latin Americans, declining Europeans Latin America In the 1980s- 1990s: Philippines, Vietnam, and South Korea Today: Chinese, Indian | Wave Two- US immigration |
| gravity model | The bigger and closer two places are, the more likely people will move between them (will travel least distance to get what they need. Natural pull factors to go to bigger cities, in terms of the quality/amount of goods and services that draw them in |
