This archipelago, with a land area of 1,978.49 km² out of a total area of 264,198.37 km² area, This area is divided into island clusters such as the Natuna Island Cluster and the Serasan Island Cluster. However, several other islands that are not located in the two clusters are spread over a wider area. This division reflects the geographical and administrative location of the district, but there are also other small islands that are outside these two main clusters and are not always included in the grouping. Administratively, this area is divided into 17 districts (kecamatan) which function to facilitate management and services for the local community and support the development of the potential of the region which is rich in natural resources and tourism. This regency also plays an important role in maintaining Indonesia's sovereignty in the northern border area.

With 69,003 inhabitants at the 2010 Census and 81,495 at the 2020 Census, most of the population are Malays with 11% of Javanese migrants, Chinese, Minang, Batak, Banjar people, Dayak people, Buginese people, Sundanese people, and tiny percentage of migrants who come from Sulawesi, Bali, and other provinces across Indonesia. The official estimate as at mid 2025 was 86,760 (comprising 44,580 males and 42,180 females).

Some 80% of its inhabitants are of Malay origin, numerous being descended from Terengganuan, Johorean, and Pattanian descent as results of contact established since 1597. The consequence of this is the usage of Terengganuan Malay beside the Indonesian language as the official language and the Malay language as a lingua franca across the Province of Riau Islands.

Indonesia's exclusive economic zone (EEZ) off the coast of Natuna is slightly overlapped by China's widely disputed South China Sea claim.
