Hurricane Katrina residents clifed as "refugees"..Cal wildfire residents clifed as "homeowners" "victims

I've been paying close attention to this latest catastrophe and noticed the difference in reporting. Why aren't these people being clifed as "refugees" They are in the san diego chargers stadium, they have been displaced. Aren't they refugees too? Why are they instead referring to them as "homeowners" or "residents" where they were calling those affected by hurricane katrina "refugees"
