Is it inappropriate to explain why I really want to live where the university is located in my job talk? I am preparing to give a job talk for
an on-campus interview for a tenure-track assistant professor position.
The university is located in city X.
I really want a job in city X
because I have many relatives living in city X,
and my parents also live a few hours by plane from city X,
and I feel that city X is a good place for my wife and I to raise our kids.

I would like to spend one slide and a minute near the end of my job talk
in order to explain why I really want to live in city X.
Would this strengthen my case,
or would this be seen by the faculty as "too much information?"
Just to put what's already in the comments into an answer:


Yes, you should convey the information you've told us to the hiring faculty.  If you've gotten a campus interview for a faculty position, they are already extremely interested and satisfied with your on-paper qualifications.  Final decisions are often strongly motivated by who they think will take the offer and who they think will stick around, happily and productively, in the job.  You list several things that would earn you lots of points on that score, and since the hiring faculty cannot and should not ask too many questions about your personal life, the way to make that information known is to tell them so explicitly.  


However,


No, you should not put that information in as a slide.  Your talk should be about your professional work.  Throwing in "I'd like it here!  Hire me!!" while people are listening to your work is jarring and shows (I think) just a soupçon of poor judgment.  I assume that your on-campus interview is structured so that anyone who is involved in hiring you has multiple opportunities to talk to you outside of the context of your job talk.  If so, then I wouldn't even bring it up at all in your talk, except possibly as an ice-breaker at the beginning or a parting shot at the very end.
