2. Zooming in for Digital Divide Issues
• Across and within Rural Areas
• Geography v Demography
Rural Divides
• Distressed Areas
• Invisible Publics
Urban Divides
• Not technologically determined
• Absence of fine-grained data
Homework Gap

3. Urban-Rural Divides in
the UK (2013)
• Difficult to Discern Impact of
Geography, controlling for SES
• OxIS Random Samples of UK
• Collaboration with Un of Aberdeen
• Disproportionately Sampling Rural
Areas (82% urban)
• Discover Differences between
Swallow v Deep Rural Areas
• Discovered Impact of Speed
See: Farrington, et al (2015).

4. Divides within Urban Areas: the Detroit Case
• Under-sampling of Distressed
Communities in (Sub)Urban Areas
• Fostering Myths of the
Disconnected and Disinterested
• Quello Center’s Study of Three
Communities of Detroit (Rocket
Fiber) – 12.1% response rate
• Great Interest
• Ingenuity in being Connected
• Mobile Only Divide Issues
Focus Group Discussion in Detroit Community Center
See: Fernandez, et al (2019).

5. Student Sourcing Data on the Homework Gap
• More than a technical challenge of infrastructure
• Absence of fine-grained data on student access in households
• MSU’s Quello-Merit Moonshot Project (Keith Hampton et al)
• 3 large intermediate school districts, 3,500 students in 200 classrooms
• Collectively gathering data on BB at home, and conducting speed tests
• Also collected information on possible implications:
• Uncompleted homework
• Career ambitions
• Time on homework
• Grades
See: Yankelevik et al (2019), and Quello-Merit homework gap project at https://www.merit.edu/services/moonshot/).

6. Simple conclusions:
Many ways to map and measure divides
Problems should drive the methods
Be open to multiple methods and modes
Don’t focus only on the ‘Holy Map’ of BB
