In terms of financial and human resources, the comparisons between the Manhattan Project and the "Uranverein" are stark. The Manhattan Project consumed some US$2 billion (1945) in government funds, and employed at its peak some 120,000 people, mostly in the sectors of construction and operations. Total, the Manhattan Project involved the labor of some 500,000 people, nearly 1% of the entire US civilian labor force. By comparison, the "Uranverein" was budgeted a mere 8 million reichsmarks, equivalent to about US$2 million (1945) — a factor of 1,000 less.
