FACTBOX: Zimbabwe: its people, land and economy

(Reuters) - An official of Zimbabwe's ruling ZANU-PF said on Tuesday President Robert Mugabe and breakaway opposition MDC leader Arthur Mutambara had signed a power-sharing deal and would form a national unity government.

Below are some facts on Zimbabwe:

* AREA: 386,900 sq km (149,400 sq miles) and landlocked. Borders Zambia to the north, Mozambique to the east, Botswana and Namibia to the west and South Africa to the south. The capital is Harare.

* POPULATION: About 13.3 million. The prevalence of AIDS, falling life expectancy and high infant death rates mean estimates are unreliable.

* LANGUAGE: The official language is English and Shona, Ndebele and other minority languages are also spoken.

* ETHNIC GROUPS: Most are of Shona or Ndebele origin. Other groups include Venda, Shangaan, Tonga and Kalanga.

* RELIGION: African traditional religions -- 55 percent; Christianity -- 45 percent; also small minorities of Muslims and others.

* ECONOMY: Central Bank Governor Gideon Gono said last month Zimbabwe's annual inflation rate, already the highest in the world, had reached 2.2 million percent.

-- From August 1, local currency was re-denominated by removing 10 zeros from a Zimbabwe dollar. The highest note was 100 billion. The new set of notes -- from Z$1 to Z$500 -- will circulate alongside the higher-denominated currency being phased until at the end of the year.

-- Zimbabwe's economic crisis -- also highlighted by chronic shortages of food and fuel, and massive unemployment -- forced President Robert Mugabe to negotiate with the main opposition Movement for Democratic Change.

FOOD SHORTAGE:

-- The U.N. Food and Agriculture Organization and World Food Program estimated in June that 2.04 million Zimbabweans risked hunger in the coming months, "peaking at about 5.1 million at the height of the hungry season between January and March 2009".

-- The report forecast maize output in 2008 would fall by 28 percent from 2007 to 575,000 metric tons and domestic cereal supply would be down 40 percent to 848,000 metric tons.
