Defence Analytical Services and Advice (DASA) was a statistical and economic unit within the MoD, initially created in 1992 from various statistics branches within the Ministry of Defence (MoD), as the Defence Analytical Services Agency. DASA was initially an executive agency of the MoD but lost its agency status on 1 April 2008, becoming an administrative unit within the MOD, changing its name to Defence Analytical Services and Advice, retaining the acronym DASA. On 1 April 2013, DASA was split into two separate units within the MoD; Defence Economics and Defence Statistics.
