Tanzania has run into trouble with the bank over its policies targeting pregnant girls before. A $300 million educational loan to Tanzania was withdrawn in 2018
over concerns about expelling pregnant girls and the introduction of a law that made it a crime to question official statistics.
The Tanzanian government amended the statistics law last year, but stopped short of any formal changes to the way it treats pregnant girls.
According to a World Bank document outlining the loan, about 5,500 girls were not able to continue their secondary education due to adolescent pregnancy and young motherhood in 2017.
Around a quarter of Tanzanian girls aged between 15 and 19 are mothers or pregnant. According to the United Nations Population Fund, the percentage of teenage girls who have given birth or who were pregnant increased to 27% in 2016 from 23% in 2010.
Child marriage, as young as 15, which has been barred since 2016, remains an issue — 36% of women aged 25-49 have been married before they turned 18, according to official data from 2016, the latest available.
