How many deaths were caused by the Dust Bowl?

Due to inaccurate record keeping at the time and that most of the affected regions were sparsely populated/rural it is impossible to know exactly how many people died. Some estimates go as high as 7,000. At least 2.5 million were left homeless or were forced to move by 1940. The long-term side-effects of dust inhalation and related diseases likely caused many more deaths over time.
