Agricultural output grew faster than the population over the century to 1770, and thereafter productivity remained among the highest in the world . This increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, though domestic production gave way increasingly to food imports in the nineteenth century as population more than tripled to over 32 million . The rise in productivity accelerated the decline of the agricultural share of the labour force, adding to the urban workforce on which industrialization depended: the Agricultural Revolution has therefore been cited as a cause of the Industrial Revolution . </P> <P> However, historians continue to dispute when exactly such a "revolution" took place and of what it consisted . Rather than a single event, G.E. Mingay states that there were a "profusion of agricultural revolutions, one for two centuries before 1750, another emphasising the century after 1650, a third for the period 1750 - 1880, and a fourth for the middle decades of the nineteenth century". This has led more recent historians to argue that any general statements about "the Agricultural Revolution" are difficult to sustain . </P>
