Education and interlocking weights

Some polling companies weigh by educational attainment.

A former adviser to the UK government wrote on social media:

There’s literally *a BIG alignment* in UK/US over years which is why e.g pollsters now must do as Vote Leave did in 2016 & *weight by education*

What does “weight by education” mean?

In survey research, weights correct for some imbalances between samples and the population.
