The departmental structure changed in 1960, when responsibility for fisheries was removed from the Home Office and added the Department of Agriculture (it then became the Department of Agriculture and Fisheries), and in 1962, when the Home and Health departments were merged (into the Scottish Home and Health Department). A new Development Department was also established in 1962. In 1973, they were joined by a new Scottish Economic Planning Department, which was renamed the Scottish Industry Department in 1983. All of the Departments had their named changed in 1991, when "Scottish Office" was prefixed to them, and at the same time the Development Department was renamed the Scottish Office Environment Department.
