About 8,000 women worked in Bletchley Park, the central site for British cryptanalysts during World War II. Women constituted roughly 75% of the workforce there. While women were overwhelmingly under-represented in high-level work, such as cryptanalysis, they were employed in large numbers in important auxiliary work, such as: operating cryptographic machinery and communications machinery; translating of Axis documents; traffic analysis; clerical duties, and many more besides.
