According to the 2015 Louisiana Laws Revised Statutes, residents of any unincorporated area may propose to incorporate as a municipality if the area meets prescribed minimum population thresholds. Municipal corporations are divided based on population into three classes: cities, towns, and villages. Those having five thousand inhabitants or more are classified as cities; those having less than five thousand but more than one thousand inhabitants are classified as towns; and those having one thousand or fewer inhabitants are classified as villages. The governor may change the classification of the municipality if the board of aldermen requests a change and a census shows that the population has increased or decreased making it eligible for a different classification. Municipalities are granted powers to perform functions required by local governments including the levy and collection of taxes and to assume indebtedness. The largest municipality by population in Louisiana in 2020 is New Orleans with 383,997 residents, and the smallest is Mound with 12 residents.
