"The village stands near Akeman-street, and near the boundary with Gloucestershire, 1½ mile E of Tetbury, and 6½ S W by W of Tetbury-road r. station; was known to the Saxons as Newantune; and has a post-office under Tetbury. The parish comprises 2,289 acres."
During the First World War, RAF Long Newnton was built on a farm, an RAF base that consisted of an aerial gunnery range, and then was used for storage of ammunition and bombs. When the war was finished great efforts were made to remove the bombs and ammunition from the site for safety. In 1939 RAF Long Newnton was made into a decoy airfield, as part of the planning for World War Two which involved strategic lighting to fool Germans yet allow the RAF fighters to avoid landing there. In 1940 the site became a training school as part of the RAF and a relief landing ground. However by 1947 the RAF base was completely unused and the land was bought privately for agricultural purposes. Three Solar farms now sit in its place however some remains of the RAF base have survived and these have become a magnet for those interested in the history. Historically the village was also known as "Long Newnton". The Fosse Way forms part of the Parish Boundary and also the country boundary with Wiltshire. Long Newnton was one of several parishes which were transferred from Wiltshire to Gloucestershire in 1930
Economy
The current average house value in Long Newnton is £700,000, an increase of £90,000 over the last ten years. Earliest records show that through history, the Long Newnton economy has significantly relied upon agriculture as a main employer. Records from 1811 show that out of the 44 families living in the Parish, 34 of them were 'chiefly employed in Agriculture' is further supported by the bar chart which shows that in 1881 agriculture continued to be the main occupation for men with 48 men employed by the trade. However by 2011, Long Newnton were no longer dependent on agriculture for the economy, while only 9 were employed in agriculture, 15 people were employed in Professional, Scientific and Technical Activities, making it the most popular trade in Long Newnton. This suggests that although in the past Long Newnton has been reliant on agriculture for trade and its economy, this is becoming less important as redients have taken up occupation in modern, technically advanced employment.

Demographics
As can be seen from the line graph, throughout 1801 to 2011 the population of Long Newnton has varied between 150 and 450. Population records start from the 1801 census when the population was just under 196, this stayed fairly stable until 1851 when the population decreased by 11 and continued to decrease until 1891 when it rose to 323. Between 1891 and 1931 it continued to vary between 323 and 284 before spiking significantly in 1951 to 419, this spike in population correlates with the Parish becoming part of Gloucestershire along with the village of Ashley and proposal transfer of Marston Maisey in 1930. Another decrease occurred in 1961 leaving a population of just 210. The population of Long Newnton then stabilised and was recorded at 211 in both 2001 and 2011. The Population Pyramid shows that Long Newnton has, what could be described as an economically stable demographic structure because it does not suffer from either a young or an aging population. Instead it benefits from having a population where the majority of the people living there would be expected to be economically active, 154 of the 210 people are within 21 years old to 70 years old.
