People in _people files not in _candidate files

[symroe]

The following are IDs that are in a *_people.yaml file but not in a *_candidates.yaml file:

alis-ballance
andrew-smith
anna-white
arlene-mccarthy
beatrix-campbell
chirs-olley
christopher-monckton
claire-edwards
david-haslett
david-knight
david-price
del-singh
gordon-johnson
henry-gent
joanna-corbin
john-tennant
john-walker-scott
kevin-doran
lisa-strachan
malcolm-macaskill
michael-hassell
michael-mcmanus
mike-scott-hayward
naseem-ayub
nick-wallis
paul-henke
phil-bloomer
rev-george-hargreaves
robert-sulley
ross-durance
saffi-price
steve-brammer
steven-mckeane
tracey-simpson-lang

Is this because the person ended up not standing as a candidate?

In the case where I want to assert "here is a full list of candidates" should I ignore these people?
