But the shortfall also affects industrialized nations such as the United States, Spain, Ireland, Italy and Sweden, according to data published by the UN Educational, Scientific and Cultural Organization (UNESCO) Institute for Statistics.The remaining teachers are needed to replace those leaving the profession for a variety of reasons such as retirement, illness or career change.Of the two million additional posts, sub-Saharan Africa accounts for 1,115,000, the Arab States for 243,000, South and West Asia for 292,000, and North America and Western Europe for 155,000.
