Does a depression always follow a recession? yes, the trough is always considered a depression. no, a depression is indicated when the recession is exceptionally long. yes, for recovery to occur, the trough must be reached. no, the economy could decline quickly and bypass recession.

Yes, a Depression is really the same as a Recession, just worse.

so a Recession is when the economy is not doing so good and unemployment may remain at a high level, if it gets worse, then the "worse recession" is called a Depression.

kinda like the difference between a storm and a hurricane, both are windy and wet, one is more destructive than the other.
