Examples of Net migration in the following topics:
-
Three Demographic Variables
- The basics of demographic population growth depend on the rate of natural increase (births versus deaths) and net migration.
- The United States illustrates how the rate of natural increase and net migration combine to create population change—the fertility rate in the U.S. is at almost exactly replacement level, but migration into the country is high enough to lead to population growth.
- Human population growth depends on the rate of natural increase, or the fertility rate minus the mortality rate, and net migration.
- Net migration is the mathematical difference between those migrating into a country and those migrating out of a country.
- However, when dealing with ethnic groups, "net migration" might have to be subdivided into physical migration and ethnic re-identification (assimilation).

Migration
- Migration is the movement by people from one place to another.
- Urbanization refers to migration from rural to urban areas.
- Yet another kind of migration, forced migration refers to the coerced movement of a person or persons away from their home or home region.
- Positive migration rates are indicated in blue; negative migration rates in orange; stable in green; and no data in gray.

-
The Effect of pH on Solubility
- The pH at which the net charge is neutral is called the isoelectric point, or pI (sometimes abbreviated to IEP).
- At a pH below the protein's pI, a protein will carry a net positive charge; above its pI, it will carry a net negative charge.
- When the proteins are added to the solution and current is applied, they migrate toward the electrode with the opposite charge (remember that opposites attract).
- For example, a protein that is in a pH region below its isoelectric point will be positively charged and so will migrate towards the cathode (negative charge).
- At this point, it has no net charge, and so it stops moving in the gel.
-
Movement and Migration
- Migration is the long-range seasonal movement of animals.
- Wildebeests migrate over 1800 miles each year in search of new grasslands .
- Although migration is thought of as an innate behavior, only some migrating species always migrate (obligate migration).
- Animals that exhibit facultative migration can choose to migrate or not.
- Additionally, in some animals, only a portion of the population migrates, whereas the rest does not migrate (incomplete migration).
-
Cell Migration in Multicellular Organisms
- Cell migration is necessary for development and maintenance of multicellularity, and occurs through varying mechanisms.
- Cell migration is a central process in the development and maintenance of multicellular organisms.
- Eukaryotic cell migration typically is far more complex and can consist of combinations of different migration mechanisms.
- The migration of cultured cells attached to a surface is commonly studied using microscopy.
- Other eukaryotic cells are observed to migrate similarly.
-
Electrolysis of Sodium Chloride
- Sodium ions migrate to the cathode, where electrons enter the melt and are reduced to sodium metal:
- Chloride ions migrate the other way, toward the anode.
- The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.
-
Induced Charge
- As such, it has no net charge.
- If the inductor is positive, electrons migrate toward it, making the uncharged object more negative in that area and positive in the region opposite it.
-
Net Income
- Net income in accounting is an entity's income minus expenses for an accounting period.
- Net income in accounting is an entity's income minus expenses for an accounting period.
- Net income is a distinct accounting concept from profit.
- In contrast, net income is a precisely defined term in accounting.
- As profit and earnings are used synonymously for income (also depending on United Kingdom and U.S. usage), net earnings and net profit are commonly found as synonyms for net income.
-
The Great Migration and the "Promised Land"
- People also frequently migrated to cities where they had family.
- The African-American Great Migration created the first large, urban black communities in the North.
- As African Americans migrated, they became increasingly integrated into society.
- This later painting, titled "During World War I there was a great migration north by southern Negroes" by the artist Jacob Lawrence, depicts African-American migration north via abstract images.
- Many African-Americans migrated North in search of a better life.

Dimensionalizing Immigration: Numbers of Immigrants around the World
- In 2006, the International Organization for Migration estimated the number of immigrants to be more than 200 million globally.
- In 2005 Europe experienced an overall net gain of 1.8 million people from immigration.
- This graph shows the worldwide net immigration rate in 2011.
