Former pilot organised large, election-day survey (8)

I believe the answer is:

exitpoll

I'm a little stuck... Click here to teach me more about this clue!

'election-day survey' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'former pilot organised large' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'organised' is an anagram indicator.
'large' becomes 'L' (eg in clothes sizes).
'pilot' with letters rearranged gives 'itpol'.
'ex'+'itpol'+'l'='EXITPOLL'

Can you help me to learn more?

I've seen this clue in The Guardian.
