1. I took wages data for each wages decile for 1999-2017. assets.publishing.service.gov.uk/government/upl…
2. Put them in a spreadsheet and looked at correlations between immigrant numbers and wage rises. Found strongest correlation was in wage rises the year following the immigration.
4. Got Excel to calculate the strength of the correlation.
-the amounts were small
-the correlation was weak
-increases in EU immigration were correlated with increased pay rises
-increases in non-EU immigration were correlated with decreased pay rises.
