1% increase in immigration leads to a 1.78%-2.97% increase in Far-Right voting (2024)

The largest electoral swings to the far right in the history of the developed world are 1930 in Germany (economic difficulty), 1956 in France (economy doing well), 1968 in the USA (economy doing well), 1973 in Denmark (economy doing well), 1992 in Israel (economic difficulty) and 2022, 23, 24 and 26 in Italy, the Netherlands, France and Germany respectively (economic difficulty).

The only way to even begin making any useful conclusions is to start with a two-axis graph.
