The baseline survey was conducted between February and May 2014, thus ending just as the first cases of Ebola were being reported. This covered 5 _,_ 775 young women, corresponding to 27% of all eligibles, and recorded information on their time use, education and skills, labor market activities, risky behaviors, marriage/pregnancies, empowerment and aspirations, expenditure/finances, and social networks.

Time use data plays an important role in our analysis. To elicit reliable information, rather than just asking about hours, we asked respondents to use a physical representation of time (beans) to show how they divided their time over the past week. We did so for broad activities (education, income generation, household chores, leisure), and also specifically for time devoted to leisure (sexual relationships with men, with friends, social activities, alone).<sup>22</sup> The survey took place during the school year so respondents could feasibly have been attending school on survey dates. The credibility of the time use data is underpinned by the fact that: (i) the number of beans recorded across categories summed up to 25 for 90% (99%) of respondents at baseline (endline); (ii) 87% of respondents report sleeping 5 to 10 hours per night; (iii) the average number of hours spent per week at ELA clubs is three, which is realistic. We convert time use measures into hours per week.

With the onset of the crisis and all fieldwork suspended, we implemented two village-level surveys. The first was a monitoring survey to ELA club mentors in treatment villages conducted in June/July 2015. It provides information on club functioning, activities and participation. The second was a village leaders survey administered between June and October 2015. It provides information on village characteristics, public facilities, impacts of Ebola (in terms of the number of households quarantined, Ebola related cases and deaths), and policy responses (such as the functioning of schools and health facilities, and other relief efforts).<sup>23</sup> After fieldwork restrictions were lifted, the endline survey was fielded between February and May 2016 (so like the baseline, taking place during the school year). As Figure 1 shows, this is around six months after cases of Ebola declined to near zero, and well after schools and markets

> 22The exact wording of the question used for the broader categories is, _”Now I would like you to do a simple exercise. Here on these cards are some ways you can spend your time in a typical week. Here are 25 beans. Please divide these beans between the cards according to how much time you spend in each activity.”_ For time use related to leisure, the exact wording of the key question is, _”Here are the 25 beans again. Here on these cards are some ways you can spend your free (leisure) time. Please divide these beans between the cards according to how much time you spend in each activity. If there are any other activities not listed on these cards, you can write them on these blank cards.”_

> 23The village leader survey collects data coded from focus group discussions held in every village. Prominent members of the socioeconomic and administrative life of the community attended these meetings, with the average focus group involving 11 participants (the minimum (maximum) was 5 (18)). 85% of these meetings were attended by a Chief (either a Paramount, Section, Regent or Village Chief). Village elders, women’s and youth leaders, imams, pastors, head teachers, nurses and ELA club mentors were also invited.
