They are mainly living in south east of Caspian Sea coasts. Many of them live as farmers and fishermen. They are closely related to other Iranian people in the Iranian plateau. In fact, the rise of the new wave of Iranian nationalism in modern history of Iran is associated with inspiration of the Pahlavi dynasty, a Mazandarani origin dynasty. During this period this ideology was fostered by Pahlavis as well as reviving pre-Islamic Iranian traditions, Persian language reforms, etc.
The local Mazandarani, which belongs to Northwestern Iranian languages, is spoken among these people and most Mazandarani people are fluent in both Mazanadarni dialect and standard Persian. However, with the growth of education and press, the differentiation between Mazandarani and other Iranian dialects are likely to disappear. Mazandarani is closely related to Gilaki and the two dialects have similar vocabularies. These two dialects retain more than Persian does of the noun declension system that was characteristic of older-Iranian languages.
Borjan states that Mazandarani has different sub-dialects and there exists a high mutual intelligibility among various Mazandarani sub-dialects. Raymond Gordon in Ethnologue lists them as Gorgani, Palani, etc. However, he calls them dialects.
Analysis of their NRY patrilines has revealed haplogroup J2, associated with the neolithic diffusion of agriculturalists from the Near East, to be the predominant Y-DNA lineage among the Mazandarani (subclades J2a3h-M530, J2a3b-M67 and J2a-M410, more specifically.). The next most frequently occurring lineage, R1a1a, believed to have been associated with early Iranian expansion into Central/Southern Eurasia and currently ubiquitous in that area, is found in almost 1/4th, and this haplogroup, together with the aforementioned J2, accounts for over 1/2 of the entire sample. Haplogroup G2a3b, attaining significant frequency together with G2a and G1, is the most commonly carried marker in the G group among Mazandarani men. The lineages E1b1b1a1a-M34 and C5-M356 comprise the remainder, of less than 10% sampled.

Assimilated groups into the Mazandarani people
In the Safavid era Mazandaran was settled by Georgian migrants, whose descendants still live across Mazandaran. Still many towns, villages and neighbourhoods in Mazandaran bear the name "Gorji" (i.e. Georgian) in them, although most of the Georgians are already assimilated into the mainstream Mazandaranis. The history of Georgian settlement is described by Eskandar Beyg Monshi, the author of the 17th century Tarikh-e Alam-Ara-ye Abbasi, in addition many foreigners e.g. Chardin, and Della Valle, have written about their encounters with the Georgian Mazandaranis.
