The most widespread language group is the Kartvelian family, which includes Georgian, Svan, Mingrelian and Laz. The official languages of Georgia are Georgian, with Abkhaz having official status within the autonomous region of Abkhazia. Georgian is the primary language of 87.7 per cent of the population, followed by 6.2 per cent speaking Azerbaijani, 3.9 per cent Armenian, 1.2 per cent Russian, and 1 per cent other languages. In the 2010, the United States federal government began the Teach and Learn English with Georgia programme of promoting English literacy in elementary school. The goal was to import English speakers from across the world to ensure that all children in Georgia spoke English in four years and replace Russian as a second language.
