Priya travels every day from Thane to her college in Mumbai and comes home each evening. Is she a migrant?
No, because she still lives in Thane. Her home has not changed.
Correct, that is commuting. Now, a family moves from a village in Bihar to Pune and settles there. Is that migration?
Yes. They crossed a boundary, changed where they live, and they are staying for a long time.
Good. And tourists who spend a week in Goa?
Not migration either. They are only visiting, so their usual home stays the same.
A nurse moves from Kochi to London to work for many years. From India's point of view, what is she?
An emigrant, because she is leaving India.
And from the United Kingdom's point of view?
An immigrant, because she is coming into the country. E for exit and I for in!
Nicely remembered. What do we call moving out of a state to another state within India?
Out-migration from the first state, and in-migration into the second.
In one year, 1,200 people moved into a town and 800 moved out. What is the net migration?
1,200 minus 800, which is plus 400. The town gained people.
The same town had 1,000 births and 400 deaths. By how much did its population change?
The natural increase is 600, and migration added 400, so the population went up by 1,000.
Exactly. Population changes through births, deaths and migration together.
moving from one place to another to live there permanently or for a considerable time.
a boundary is crossed, the usual home changes, and the stay is long.
daily commuting, holidays and short visits, because the usual home stays the same.
an emigrant leaves a country, and an immigrant enters one; the same person can be both.
people moving in minus people moving out; positive means a gain and negative a loss.
births, deaths and migration together decide how a place's population changes.
A family that moves from a village in Bihar to Pune and settles there are migrants; Pune is their destination and the village their place of origin.
A student who travels daily from Thane to a college in Mumbai is a commuter, not a migrant, because her home does not change.
A nurse who moves from Kochi to London is an emigrant from India and an immigrant in the United Kingdom.
A town where 1,200 people move in and 800 move out in a year has a net migration of +400.
Cross a line and change your door, stay a while, a migrant for sure.
Raju takes the train to the city every morning and back every night, so he is a commuter. His cousin Sita packed her things, moved to the city and rented a room for her new job, so she is a migrant. Both travel, but only Sita changed her home.
E for Exit, I for In: an Emigrant exits a country, and an Immigrant comes in.
H.B.T. - Home changes, Boundary is crossed, Time spent there is long.

The movement of people from one place to another to live there permanently or for a considerable time.
A person who moves from one place to another to live there.
The place a migrant leaves; also called the source area.
The place a migrant moves to.
A person who leaves their own country to live in another country.
A person who comes into a country from another country to live there.
The number of people moving into an area minus the number moving out of it.
Travelling regularly between home and a place of work or study without changing one's home.
Migration is the movement of people from one place to another to live there, permanently or for a fairly long time; this lesson defines it carefully and introduces the key terms used to describe it.
Not every journey is migration. This lesson sets out the three parts of the definition (moving across a boundary, changing one's usual place of residence, and staying for a considerable time) and shows why daily commuting and holidays do not count. It then introduces the words geographers use: migrant, place of origin and destination, emigrant and immigrant, in-migration and out-migration, and net migration, with simple calculations. Finally, it explains how the Census of India records migrants and how migration, together with births and deaths, changes the population of a place. These terms are used throughout the lessons on the types, reasons and effects of migration.
Migration is the movement of people from one place to another with the aim of living in the new place, either permanently or for a considerable period. People who move in this way are called migrants. The place they leave is the place of origin (or source area), and the place they move to is the place of destination.
A movement counts as migration when:
The same person can be both an emigrant and an immigrant. A nurse who moves from India to the United Kingdom is an emigrant from India's point of view and an immigrant from the United Kingdom's point of view.
Net migration is the difference between the number of people who move into an area and the number who move out:
Net migration = number of people moving in − number of people moving out
If 1,200 people move into a town in a year and 800 move out, net migration is 1,200 − 800 = +400, a net gain. If 150 people move into a village and 420 move out, net migration is 150 − 420 = −270, a net loss.
The population of a place changes in two ways: through births and deaths (natural change) and through migration. For example, a town of 50,000 people has 1,000 births and 400 deaths in a year (a natural increase of 600), while 1,200 people move in and 800 move out (net migration of +400). Its population grows by 600 + 400 = 1,000, to 51,000.
The Census of India records a person as a migrant if the place where they are counted is different from their place of birth, or from their place of last residence. These records show how many people move, from where to where, and why.
