It covers an area of 21,693.51 km2, and had a population of 182,001 at the 2010 Census, which grew to 311,969 at the 2020 Census.

The regency covers the entire south coast of its province (the only other coastal regency of Central Papua is Nabire Regency, covering the north coast of the province). The western half of this southern coastline, identified as "West Mimika" in the table below, forms the coastal access to the landlocked regencies to its north - Deiyai Regency and Dogiyai Regency. During the 2020s, Mimika was involved in a border dispute with neighboring Deiyai and Dogiyai regencies, resulting in the Kapiraya conflict.
