The rapid rate of growth decreased after the war, and population only increased from 1,137 in 1951 to 1,347 in 1971. This was particularly affected by the withdrawal of steam power on the railway in the 1960s, and the resultant reduction in the staff needed at the locomotive sheds. Some of the younger railwaymen found employment at the expanding Llanwern steelworks. Many of the older railwaymen retired, encouraged by security of tenancy for the desirable Garden Village housing. This gave Rogiet a population in 1966 that consisted of 40% retirees, with an unusually elderly population in the 1960s and 1970s, leading in turn to an low provision of schools and other amenities, although a thriving allotment society continues to this day. The local birthrate fell by over 50% in the 15 years from 1946 to the 1961 census.
