The chart given compares the number of girls per 100 boys enrolled in primary, secondary, and tertiary education in developing and developed countries. This comparison is made in two specific years, 1990 and 1998.
Overall, in 1998 there was a slightly higher number of girls enrolled in the three stages of education compared to 1990. However, while primary and secondary education in developed countries had a balance in its enrollment rates, developing countries experienced a decrease in the proportion of female students, especially at the tertiary level.
In primary education, both developing and developed countries have relatively balanced enrollment rates. Developing countries had approximately 83 girls per 100 boys in 1990, which increased slightly to 87 by 1998. Developed countries, however, showed a more consistent balance, with about 95 girls per 100 boys in both years.
As for secondary and tertiary schooling, developed countries had a balanced number of enrollments, with tertiary one overpassing the parity and having 110 girls per 100 boys in 1990. However, developing countries presented a decrease from around 70 to just over 60 percent of girls.
