"Migration for employment is an important global issue, which now affects most countries in the world. Two major labour market forces are in operation today that result in increased migration for work – many people of working age either cannot find employment or cannot find employment adequate to support themselves and their families in their own countries, while some other countries have a shortage of workers to fill positions in various sectors of their economies.
Other factors include demographic change, socio-economic and political crises, and widening wage gaps within, as well as between, developed and developing countries. There is consequently much movement across borders for employment, with women independently migrating for work in considerably greater numbers than in the past and now comprising about half of all migrant workers."
