Population decline in particular was noted to be faster in inner city areas than in outer ones, however a decline was noted throughout the 1970s, 80s, and 90s in both inner and outer city areas. Jobs declined between 1984 and 1991 (a decline observed particularly among men), while outer areas saw job growth (particularly among women). The UK also saw urban areas become more ethnically diverse, however urban decline was not limited to areas which saw population changes. Manchester in 1991 had a non white population 7.5% higher than the national average, but Newcastle had a 1% smaller non white population.
