Not really.
What there is, are way fewer people who are going to affirmatively answer the question, "do you have guns in your home", when blindly called by a stranger representing a polling agency, for reasons that in 2018 should be abundantly obvious to you.
Because nobody thought of that before? It is accounted for in the survey.
