In 1856 coal output in North Staffordshire was 1.3 million tons a year. By 1864 it had risen to over 3 million tons, and by 1870 it stood at 4 million tons. Despite pit closures the coalfield output had remained remarkably constant throughout the 20th century, varying from 6.7 million tons in 1907 to 7.4 million tons in 1939, 6.6 million tons in 1948 and to 4.6 million tons in 1971.
