Figure 1 Distribution of secondary schools in (A) Tanzania, (B) Cambodia, and (C) the Dominican Republic is used to estimate travel time of students. This is useful in exploring geographic variation in spatial access to schools by the youth and its influence on school attendance.

Figure 2 Model based geostatistical methods were utilised to make predictions of the percentage of adolescents who were out-of-school in (A) Tanzania, (B) Cambodia, and (C) the Dominican Republic at a 1 km spatial resolution. The red areas are where there is a high percentage of school non-attendance with long distances to schools being one of the factors contributing to this.
