Total number of the Azerbaijani disapora varies by sources, however, at least 5–10 million Azeris live outside of Iran and Azerbaijan.

According to Ethnologue, there were over 1 million Azerbaijani-speakers of the north dialect in southern Dagestan, Armenia, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Russia, Turkmenistan, and Uzbekistan as of 1993.

The Ethnologue figures are outdated in the case of Armenia, where the Nagorno-Karabakh conflict has affected the population of Azerbaijanis.

[33] Ethnologue further reports that an additional 1 million Iranian Azerbaijanis live outside Iran, but these figures most likely are a reference to the Iraqi Turkmen, a distinct though related Turkic people.

The majority of Azerbaijanis have settled in the states of California, New Jersey, New York, Michigan, Pennsylvania, Texas and District of Columbia.

[45][46][47][48] Azerbaijan Society of America which is the first Azerbaijani-American community organization was established in 1957 in New Jersey, USA by Naghi Sheykhzamanli.

USACC provides the improvement of network services between governmental and non-governmental entities, business organizations of the US and Azerbaijan.

The organization arranges series of events, exhibitions, and seminars in research centers related to Azerbaijani culture.

The members of the organization send statements and letters to the president, all state delegates, senators, congressmen, as well as to the press, about the Khojaly Massacre, March days, the Nagorno-Karabakh conflict between Armenia-Azerbaijan and other issues.

[58] In the corresponding timeframe, Azerbaijani inhabitants of the region would be subjected to ethnic cleansing from the Armenian side, resulting in massacres and deportations of the popuation.

[59] In addition, Stalinist population transfer policies resulted in the deportation of 100,000 Azeris from the Armenian SSR between 1930 and 1952.

[60][61] Many Azerbaijanis are assumed to be involved in the Basmachi movement, a Turkic uprising which was led by Enver Pasha against the Russian Republic, and later Bolsheviks, inspired by Islamic beliefs.

[64] Another primary reason why Azeris may reside in the region is the Soviet-era labour migration, which could have also affected Turkic populations of South Caucasus.

Prominent Central Asians of Azerbaijani origin include: Hajibala Abutalybov, Stalik Khankishiev, Rafael Fiziev, Elnur Hüseynov and others.

The Heydar Aliyev Park was opened in the Kartepe municipal area on the eve of the World Azerbaijanis Solidarity Day in 2010 as a result of the activity of Turkish-Azerbaijani Associations Federation.
