Cernon is a rural commune, because it is one of the municipalities that are not very little dense, in the sense of the municipal gate of density of INSEE ^{[ Note 1 ] , [ 3 ] , [ 4 ] , [ 5 ]} .

In addition, the town is part of the Oyonnax attraction area, of which it is a town of the Crown ^{[ Note 2 ]} . This area, which brings together 40 municipalities, is categorized in the areas of 50,000 to less than 200,000 inhabitants ^{[ 6 ] , [ 7 ]} .

The town, bordered by an inner body of an area greater than 1 000 hectares, Lake Vouglans, is also a coastal commune within the meaning of the law of January 3, 1986 , called coastal law ^{[ 8 ]} . Specific town planning provisions are applied there to preserve natural spaces, sites, landscapes and ecological balance of the coast, such as the principle of unconsciousness, apart from urbanized spaces, on the band coast of 100 meters, or more if the local town planning plan provides ^{[ 9 ] , [ ten ]} .

The IGN also provides an online tool to compare the evolution over time of the soil occupation of the municipality (or territories to different scales). Several eras are accessible in the form of aerial cards or photos: the Cassini card ( XVIII ^{It is} century), the staff map (1820-1866) and the current period (1950 to today) ^{[ twelfth ]} .

The evolution of the number of inhabitants is known through the population censuses made in the municipality since 1793. From 2006, the legal populations of the municipalities are published annually by INSEE. The census is now based on an annual information collection, successively concerning all the municipal territories during a period of five years. For municipalities with less than 10,000 inhabitants, a census survey relating to the entire population is carried out every five years, the legal populations of the intermediate years being estimated by interpolation or extrapolation ^{[ 15 ]} . For the municipality, the first exhaustive census falling within the framework of the new system was carried out in 2004 ^{[ 16 ]} .

In 2020, the town had 234 inhabitants ^{[ Note 4 ]} , in decrease of 7.51%compared to 2014 (Jura: −0.72%, France excluding Mayotte: +13%).
