Digestible summary on the impact of immigration on employment rate on native worker populations: immigration rate correlates with lowered employment rate for native workers in the

Impact also variable according to educational level of native workers - for University educated, there is zero impact, whilst lower educated native workers are most heavily impacted by imported labour.
