Explain Three Terms Used To Describe Populations

Most major emigrations are caused by some kind of collapse, whether it is economic collapse or collapse of

Introduction: Not all limiting factors are related to a population’s density. Density-independent limiting factors affect a population regardless of its size and density.

Besides the total size of the population, one of the most significant demographic characteristics of a population is the age and sex structure. The immigration has had a major influence on both the size and the age structure of the U.S. population. The U.S. population has experienced remarkable growth since 1950. The number of women slightly outnumbered the men.

Population size refers to the estimated total number of individuals of a specific species in a given habitat or area at a given time. Population density is the number of individuals of a specific

There are two main componetns to population change, in this case population growth. These are natural increase and migration.

Have you ever wondered why some country's population is not as large as others, or why some are increasing while others are decreasing? The population growth rate definitely affects communities in an area. It is a measurement that combines both natural increase rate and net migration rate to calculate the total population increase of

Population is also based on size, age structure, density, sex ratio, and fecundity. The different size of population tends to, or can have a major impact on any economy. The size and density dealing with a population are the two most important issues scientist use to understand,

Words which are compared to immigrant are emigrant and migrant. These three words are similar in the fact that they both include the act of immigration. The difference is that Migration is not a permanent at. When people think of migrant, they think of birds. When a bird migrates, it does not stay at the location permanently, it goes down to usually wait out a climates seasonal change. Emigration is the act of moving somewhere to temporarily live, or work in another country.

Immigration is when someone, or a group of people want to move somewhere else.” Also the most popular reason why most people immigrate to somewhere

An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education,

The Demographic environment relates to the structure of populations (Oxford Dictionaries | English, 2017). The factors that contribute to the demographic environment relevant to this report are location and density of the population.

1. Universal- This traget population the whole population or community. The people in the community or popultionis not chosen based on any specic critrer. They usually share the same risk. For exsample if you wanted to do a health program it would be for the whole community and targeted to everyone who lives their. it would not be based on age, race, etc.

The dictionary meaning of migration is to movement from one part of something to another. Human migration is the movement of people from one place to another place ( Managalam, 2015).It is of several types such as temporary, permanent, international, internal, voluntary or forced. As the name defined permanent migration is the one in which a person move from his original place or country to another place or country and has no plans to move back to their original home. However, temporary migration is movement from one place to another for limited time. Forced migration is the one in which people have no choice but to move and opposite is true for voluntary migration in which a person make the choice to move out. Internal migration is the movement within the country whereas international migration is the movement from one country to another country(e Schooltoday, 2006). An example of internal migration is the movement of people from Punjab to Haryana whereas an example of international migration is the movement of people from India to Canada.

Fun fact:There is also different types of migration. “Economic migration” is when people are migrating to a country that has a higher percent rate of getting a job. “Social migration” is when you are migrating to start a new life or to live closer to your family. “Political migration” is when people are moving to escape corrupted government or civil war. “Environmental migration” is when natural disasters destroy homes and people try to start a new life in a new country.

As population increases, the need to expand becomes more evident. The huge consumption and need for more food, land, water, and energy have
