Severe caste disparities also exist. Discrimination of lower castes has resulted in high dropout rates and low enrollment rates. The National Sample Survey Organisation and the National Family Health Survey collected data in India on the percentage of children completing primary school which are reported to be only 36.8% and 37.7% respectively. On 21 February 2005, the Prime Minister of India said that he was pained to note that "only 47 out of 100 children enrolled in class I reach class VIII, putting the dropout rate at 52.78 percent." It is estimated that at least 35 million, and possibly as many as 60 million, children aged 6–14 years are not in school.
