Emigration is the act of leaving one's country or region to settle in another. It is the same as immigration but from the perspective of the country of origin. Human movement in general is termed migration. There are many reasons why people might choose to emigrate. Some are for reasons of religious, political or economic freedom or escape. Others have personal reasons such as marriage. Some people living in rich nations with cold climates choose to move to warmer climates when they retire.

Emigration had a profound influence on the world in the 18th, 19th, and 20th centuries, when millions of poor families left Europe for the United States, Canada, Brazil, Argentina, the rest of Latin America, Australia and New Zealand.

Even though definitions may be vague and vary somewhat, emigration/immigration should not be confused with the phenomenon of involuntary migration, such as instances of population transfer or ethnic cleansing.

Motives to migrate can be either incentives attracting people away, known as pull factors, or circumstances encouraging a person to leave, known as push factors, for example:

Loreena Isabel Irene McKennitt, CM, OM (born February 17, 1957) is a Canadian singer, composer, harpist, accordionist and pianist who writes, records and performs world music with Celtic and Middle Eastern themes. McKennitt is known for her refined, clear soprano vocals. She has sold more than 14 million records worldwide.

McKennitt was born in Morden, Manitoba of Irish and Scottish descent to parents Jack (died 1992; a livestock dealer) and Irene McKennitt (1931-2011; a nurse). She moved to Stratford, Ontario in 1981, where she still resides.

When Loreena was young she wanted to become a veterinarian but she found that music chose her rather than she it. Developing a passion for Celtic music, she learned to play the Celtic harp and began busking at various places, including St. Lawrence Market in Toronto in order to earn money to record her first album.

McKennitt's first album, Elemental, was released in 1985, followed by To Drive the Cold Winter Away (1987), Parallel Dreams (1989), The Visit (1991), The Mask and Mirror (1994), A Winter Garden (1995), The Book of Secrets (1997), An Ancient Muse (2006), A Midwinter Night’s Dream (2008), and The Wind That Shakes the Barley (2010). All of her work is released under her own label, Quinlan Road.
