Sample size: planned number of observations
70,000-80,000 individual youth who were SYEP participants, subject to data cleaning and de-duplication across study years. Additionally, in order to compare our study population to the broader SYEP applicant pool, we may collect data on the broader population of all youth who applied to SYEP in 2016 and 2017, even if they did not participate in SYEP. This broader group would be on the order of 200,000 individual youth. Additionally, we expect some non-compliance driven by factors such as whether supervisors received our survey recruitment emails and clicked on the survey invitation link. Whether a supervisor clicks on the survey invitation link should not differ between treatment and control youth on average, since survey recruitment emails give no indication of which youth were randomized to treatment or control. As such, we may separately analyze subsets where compliance is likely to be higher, but treatment is still random, such as youth who had a supervisor who clicked on a survey invitation link.
