The number of senior secondary schools almost doubled as well, with fourfold increases in Arsi, Bale, Gojjam, Gondar, and Wollo. The pre-revolutionary distribution of schools had shown a concentration in the urban areas of a few administrative regions. In 1974/75 about 55 percent of senior secondary schools were in Eritrea and Shewa, including Addis Ababa. In 1985/86 the figure was down to 40 percent. Although there were significantly fewer girls enrolled at the secondary level, the proportion of females in the school system at all levels and in all regions increased from about 32 percent in 1974/75 to 39 percent in 1985/86.
