*Note: AnA asteriskcaret (^) indicates the two municipalities and nine raions which previously constituted [[Izmail Oblast]] until that former oblast's merger with Odesa Oblast on 15 February 1954; these areas lie to the west of the [[Dniester]] River, and formerly constituted the territory known as the [[Budjak]] (southern Bessarabia). In the 18 July 2020 reorganisation, these nine raions were reduced to three, which also incorporated the two former independent cities.
*Note: Asterisks (*) Though the administrative center of the rayonraion is housed in the city/town that it is named after, cities do not answer to the rayonraion authorities only towns do; instead they are directly subordinated to the oblast government and therefore are not counted as part of rayonraion statistics.
