That's not true. While most voters from low income households supported leaving the EU (as shown in the report you linked), 59% of leave votes came from middle class voters and only 17% of Leave votes were from skilled manual workers. The majority of middle class voters supported remaining, but because there are so many of them, middle class voters also made up the majority of leave voters. This 5 minute report [0] from the BBC looks into where the votes for Brexit came from and how the different classes voted.

I should have said they were the sting demographic.

Skilled manual workers is a very specific, carefully selected sub-group of manual and low income workers, chosen just for the purposes of the narative. Why that specific sub-group? A lot of skilled manual workers are even middle class.

Middle class voters are the majority of voters, so they account for well over 59% of remain voters as well. Manual labour and low income voters made the break though, no other significant demographic was more likely to vote for Brexit.
