Developing an accurate picture of the state of access to post-secondary education around the world is hampered by gaps in data within even the most developed nations. For example, the European Commission’s Eurydice Report notes the considerable variation that exists among EU countries in those characteristics of the student body that are monitored and at what stages. Migrant status data, for instance, is captured in 13 systems and data on student and staff ethnicity in only 8. Socio-economic status of students is monitored in 19 systems. At the global level, UNESCO data cites the unavailability of data for 97 of 214 countries in presenting tertiary enrollment figures .
