Using microdata samples from the 1851 and 1881 censuses of England and Wales, this article explores patterns in the employment and retirement of older men in the second half of the nineteenth century. The article argues that male labour-force participation rates were stable over these years, and indicates that the major decrease did not occur until after 1881. Despite this static picture of employment of older men, there were structural changes in the economy, demonstrated here by alterations in occupational profile. Those occupational groups shown to be in decline were more likely to have an ageing workforce. Changing age profiles of certain occupations are reported, giving evidence of deskilling and the marginalisation of older men in the workforce through technological change. This article also suggests that differences in household composition where older men were present may be related to economic activity.
