Jimma is one of the zones of the Ethiopian Region of Oromia. Jimma is named for the former Kingdom of Jimma, which was absorbed into the former province of Kaffa in 1932. Jimma is bordered on the south by the Southern Nations, Nationalities and Peoples Region, the northwest by Illubabor, on the north by Misraq Welega, and on the northeast by Mirab Shewa; part of the boundary with Misraq Shewa is defined by the Gibe River. The highest point in this zone is Mount Maigudo (2,386 m). Towns and cities in Jimma include Agaro, Genet and Saqqa. The town of Jimma was separated from Jimma Zone and is a special zone now.
The Central Statistical Agency (CSA) reported that 26,743 tons of coffee were produced in this zone in the year ending in 2005, based on inspection records from the Ethiopian Coffee and Tea authority. This represents 23.2% of the Region's output and 11.8% of Ethiopia's total output, and makes Jimma one of the three top producers of these goods, along with the Sidama and Gedeo Zones.
Historically, Jimma has been considered one of the food-exporting areas of Ethiopia, but beginning in 1997 poor crops harvests and the appearance of crop diseases such as Grey leaf spot, caused by the fungus Cercospora zeaemaydis (not previously common in Ethiopia) led to a deterioration in conditions. By 1999, signs of the seriousness of the situation included empty household granaries, people begging and committing crimes in the hope they will be fed in jail, sending children to live with relatives or friends, and reduced student enrollment in schools.
Based on the 2007 Census conducted by the CSA, this Zone has a total population of 2,486,155, an increase of 26.76% over the 1994 census, of whom 1,250,527 are men and 1,235,628 women; with an area of 15,568.58 square kilometers, Jimma has a population density of 159.69. While 137,668 or 11.31% are urban inhabitants, a further 858 or 0.03% are pastoralists. A total of 521,506 households were counted in this Zone, which results in an average of 4.77 persons to a household, and 500,374 housing units. The three largest ethnic groups reported in Jimma were the Oromo (87.6%), the Amhara (4.05%) and the Yem (3.12%); all other ethnic groups made up 5.23% of the population.
