I live downtown and can think of a dozen neighbors (both renters and condo owners) who moved during or just after the pandemic. Most of them had no children, but some did. Their reasons for moving were mostly for job or relationship, or their job changed to 100% permanent remote work and they moved to more of a vacation area. The ones in the first category are now in Boston, DC, Portland ME, New Orleans, and LA. The ones in the second category are in places like Vermont, Ogunquit, NorthHampton, Cape Cod, Old Saybrook.
