Mayfield is a community in Midlothian, Scotland, located just south of Dalkeith near Edinburgh between the A68 and the A7 south. It had an estimated population of 13,570 in 2016. This housing development was built in the 1950s as overspill accommodation for the colliery workers of nearby Newtongrange and Easthouses and for other essential workers, as well as to house the workforce for a small but relatively successful industrial estate. The decline of the coal industry in the 1980s led to the closure of the collieries.
