What were the changes in the U.S. on the home front during WW2?

World War II caused many changes on the home front.  One of the largest changes was that a significant percentage of working age men went overseas to fight.  This led to major changes in the workforce.  Women, who typically were housewives when married, had to go to work to meet workforce demands.  There were additional demands because of increased production of war related materials (from parachutes to tanks).  

Food became rationed, and distribution of food products were regulated by the ration boards.  Gasoline was also regulated, and common items such as rubber, steel, and grease were collected in drives to be used for the war effort.  There was fear that the Japanese or Germans could attack on U.S. soil, so many houses had black out curtains, which they used during black out drills.  Families also were supposed to have certain supplies on hand in the event of an attack.  This was a time of both fear and unity in the United States.  There was fear that the U.S. could lose the fight or that the United States would be attacked.  There was also unity as Americans got behind the war effort.
