[5] Clayworth was described in John Bartholomew's Gazetteer of the British Isles of 1887 as having a population of 439, with 2,076 acres of land.

[6] Heinrich Mutschmann, writing in 1913, thought that the place-name Clayworth referred to the clay soil of the township.

[7] More modern scholarship however inclines to the view that the name seems to contain the Old English word, clawu, a claw + worð (Old English), an enclosure, so 'Claw of land enclosure', and suggests that the claw-shaped feature may be the low, curving hill here.

[10] A stagecoach bus link, number 97, runs through Clayworth on its Retford to Gainsborough service every 2 hours.

[11] Peter Laslett undertook a study of Clayworth monitoring migration and population changes during the 12 years from 1676 to 1688.

[12] The purpose of the study was to collect detailed data on the residents of Clayworth, it was undertaken by people who lived in the parish itself, the church wardens.

The findings from this study showed how 61% of Clayworth's population had migrated away from the village over the 12-year study period, a variety of reasons were suggested including people choosing to move parish to remarry and spinsters who were not socially tied to the village, although the real reasons are unknown.

[13] The highest level reached by Clayworth’s population, according to census statistics, was in 1841 when 627 residents were recorded as living in the village.

[15] At the time of the 1881 census the biggest family in Clayworth were the Taylors, with 26 people sharing this surname.

[20] The majority, 200 residents, in Clayworth were living in a couple, 173 of those residents were married, this follows the general trend of the population with people choosing to marry later in life, 53 were registered as single and 38 divorced/widowed at the time of the census lived in Clayworth.

[29] The oldest memorial in the church is a floorstone which holds a worn inscription to a rector, dating to 1448.
