Why are you assuming the rapid increase in LA’s population from 2006 to 2010 did not have a significant portion of temporarily displaced people moving back?
Like, there are entire journals and programs of study devoted to it. I’m not just guessing here.
According to this study, almost a third of displaced people returned to the same dwelling by some time in 2006. https://pmc.ncbi.nlm.nih.gov/articles/PMC4048822/
Today, numbers suggest that around 60%, almost two-thirds returned. https://en.wikipedia.org/wiki/Displacement_after_Hurricane_K...
