What % of faculty in your department have stay-at-home spouses?
How should you classify those faculty whose spouses stayed at home while the kids were young and then went back to work? I would not include them in my own count of stay-at-home spouses. My own calculation represents the % who have stay-at-home spouses right now, including those without kids but with a non-working spouse or long-term significant other.
I would also not include in my SAH category those faculty whose spouses have part-time jobs. Let's count employed spouses as employed spouses.
