My team’s latest research project is understanding how gender, age, education and marriage are related for Qatari women. We’re a few weeks into the study which involves survey data, interviews, and focus groups. The initial survey asks respondents to share their age, educational level and marital status. Over and over again, a number of respondents said, “I don’t know my grandmother’s age when she was married.”

Or they’ve had to call their mother to see how much education her mother had completed.

Do you know this information about your grandparents? Were they married as high school graduates or teenagers?
