Iran's population increased dramatically during the later half of the 20th century, reaching about 75 million by 2011. In recent years, however, Iran's birth rate has dropped significantly. Studies project that Iran's rate of population growth will continue to slow until it stabilizes above 100 million by 2050. More than half of Iran's population is under 35 years old (2012).
In 2009, the number of households stood at 15.3 million (4.8 persons per household). Families earn some 11.8 million rials (about $960) per month on average (2012).
According to the OECD/World Bank statistics population growth in Iran from 1990 to 2008 was 17.6 million and 32%. The literacy rate was 80% in 2007, and 85% in 2008.
According to the 2011 population census the population of Iran was 75 million, a fourfold increase since 1956. Between 1976 and 1986, an average annual population growth of almost 4% was reached, but due to decreasing fertility levels the growth decreased to 1.3% between 2006 and 2011.

The largest linguistic group comprises speakers of Iranian languages, like modern Persian, Kurdish, Gilaki, Mazandarani, Luri, Talysh, and Balochi. Speakers of Turkic languages, most notably Azerbaijanis, which is by far the second-most spoken language in the country, but also the Turkmen, and the Qashqai peoples, comprise a substantial minority. The remainder are primarily speakers of Semitic languages such as Arabic and Assyrian. There are small groups using other Indo-European languages such as Armenian, Russian, Pashto; Georgian (a member of the Kartvelian language family), spoken in a large pocket only by those Iranian Georgians that live in Fereydan, Fereydunshahr. Most of those Georgians who live in the north Iranian provinces of Gilan, Mazandaran, Isfahan, Tehran Province and the rest of Iran no longer speak the language but keep a Georgian conscience. The Circassians in Iran, a very large minority in the past and speakers of the Circassian language, have been strongly assimilated and absorbed within the population in the past few centuries. However, significant pockets do exist spread over the country, and they are the second-largest Caucasus-derived group in the nation after the Georgians.
