N.C. Gen. Stat. § 160A-486
When a newly incorporated municipality is not included in the most recent federal census of population but otherwise qualifies for distribution of State-collected funds allocated wholly or partially on the basis of current population estimates, the municipality shall be entitled to participate in the distribution of these funds by reporting all information designated by the Office of State Budget and Management. An estimate of this city's population will be made by the Office of State Budget and Management in accordance with procedures designated by that office. The estimate will be certified to State departments and agencies charged with the responsibility of distributing funds to local governments along with the current population estimates for all other municipalities.
