Between 1811 and 1961 records of the population of Copgrove are available and these show that from 1811 the population remained fairly constant for the next 10 years before making a dip to 87 in 1931. 1940 had the biggest increase in population rising to 120 inhabitants. After 1891 the population of the Parish continued to decrease down to its lowest number of 60 in 1931. In 1951 however the population was recorded at 86. This could have been because of the baby boom that occurred between the late 1940s and early 1960s.
