KINSHASA (Reuters) - Strong economic growth helped Democratic Republic of Congo create around 100,000 jobs per year from 2012-14, the prime minister’s office said on Tuesday, but unemployment remains above 40 percent in a country wrecked by war and corruption. Congo - which vies with Zambia for the title of Africa's largest copper producer - posted economic growth of 9.5 percent last year, and this should rise to 10.3 percent this year, Augustin Matata Ponyo's office said in a statement. Ponyo became prime minister in 2012. His office did not spell out the methodology used for its unemployment survey but it appeared to ignore much of the informal economy, which provides jobs for many of Congo's roughly 67 million people. The data collection process would be revised for the next survey to include a broader range of jobs, it said. The most recent prior unemployment data was from 2000, when the rate stood at 66.90 percent. The International Monetary Fund's number two official, David Lipton, praised Congo’s growth and macroeconomic stability during a visit to the capital Kinshasa in March but said more needed to be done to promote inclusive growth. Despite vast mineral riches that also include cobalt and diamonds, Congo ranks 186 out of 187 countries on the U.N. Human Development Index, largely due to continuing conflict in its war-torn east and mismanagement of its natural wealth.
