Migrants have a profound impact on the labour market of the country to which they move. They tend to be concentrated in particular localities, and in particular occupations and branches of industry. This concentration makes their presence in the local labour market very noticeable to non-migrant workers. There is a great deal of policy and public concern, often fanned by alarmist reporting in the media, that a large influx of migrant labour into the labour market will depress the wage levels of non-migrant workers, especially those with the same skill levels as migrants. Moreover, it is often anticipated that migrants will displace non-migrant workers in some occupations and industries, or push them out of the labour market altogether.
