(1) N = 7,562 (2) N = 9,444 individuals answer the survey at waves 1, 2, and 4. However, some respondents do not answer all the questions. Only 7,562 individuals answer all questions at all waves. As a consequence, the overall individual attrition rate is 20% (7,562/9,444) since missing observations at any wave lead to attrition in a balanced sample.
