I assume you are using that phrasing as a proxy for "they want to date". To note, chosing a field with higher ratio of women can be good for completely different reasons. After spending years in almost 100% male environments, moving to more balanced and diverse environments was like night and day, the toxicity was mostly gone, discussions and communication would be more interesting etc. I heard the same for women moving away from women only places as well. So yes, looking at the ratio can be plenty helpful outside of any dating concern.
