to the , abbreviated in Russian as ОКТМО. Federal legislation introduced on May 27, 2014, added the territorial units of urban okrug with intra-urban divisions and their constituent divisions (Intra-urban district).( Additional federal legislation introduced on May 1, 2019, added the territorial unit of municipal okrug. The purpose of the creation of municipal okrugs was to transition the two-tier system of the municipal districts to a single-tier system of the municipal okrugs, thereby reducing the number of local governments and thus reducing the cost of local government on the state. This legislation also set standards for the incorporation of new urban okrugs and the change in status of existing ones. In urban okrugs, at least two-thirds of the population must live in the urban settlement(s) within, and the population density must be five times the national average. Existing urban okrugs which do not meet the requirements must be reincorporated as municipal okrgus by 2025. The change was implemented out of concern that some small towns had been incorporated as urban okrugs and given all of the taxing powers and municipal service standards of much larger cities, which in the words of State Duma deputy Viktor Kidyaev turn "villagers into townspeople."
