The districts of England (also known as local authority districts or local government districts to distinguish from unofficial city districts) are a level of subnational division of England used for the purposes of local government.

With a population of 575,400 in mid-2016, the City of Sheffield is England’s third largest district authority. The city grew rapidly during the industrial revolution. In 1801 its population was 60,100. By 1851 it had increased to 161,500 and by 1901 it was 451,200. At its peak, in 1951, the population numbered 577,050.

There is a clear bulge in the population in the 20 to 24 age group. This is caused by Sheffield’s significant student population at its two universities. The increase in recent years is largely the result of 2 factors:

• There are now more births than deaths in Sheffield, resulting in a positive ‘natural change’ in the population.

• There has been an increase in the level of international migration to Sheffield.

Sheffield's population is projected to increase by around 88,600 people over the 25-year period to 652,300 in 2039.
