Dear Megan, thank you for your message. Indeed, more and more countries are interested in measuring volunteer work using the modular approach recommended by the ILO Manual published in 2011. The work done by you team, the UNV, the ILO and statisticians from different countries between 2008 and 2011 was crucial to set this trend. The Resolution I of the 19th International Conference of Labour Statisticians in 2013 set volunteering as a distinct form of work and offered countries additional reasons to measure it.
The analysis of the national efforts to implement the ILO Manual’s recommendation since 2011 have helped the ILO identify some key measurement problems. Thanks to the timely and generous support from the UNV, the ILO was able to dedicate time and resources to address those problems and come up with solutions.
One of the problems was the measurement of all productive activities performed by people without remuneration and for others. As observed, when asked about helping someone, people tend to speak about their direct actions. Therefore, those providing unpaid services talk about work (tasks performed, exactly what we want). Those making donations, however, talk mainly about the goods given to others and not about tasks performed to produce and deliver them (which is unpaid work performed for others).
Consequently, to capture the work related to donation-making ILO developed questions to capture work done at different stages of the process: collection/purchase, production/processing and distribution/delivery of donated goods. These questions were tested in Ukraine and Senegal using qualitative and quantitative methods, and proved efficient in “recovering” important number of volunteers.
For example, in Ukraine 7% of 7,000 respondents aged 15 years and older who participated in the field test said that they didn’t do any volunteer work during 4 weeks, but mentioned doing some work to donate goods/products when asked additional questions. A similar rate was observed in Senegal on a sample of 1,760 respondents.
Of course, as you mentioned, in some cases it is difficult to distinguish clearly between services provided for others and for own family. Often people do such work simultaneously (e.g. looking after own and a neighbor’s children, cooking for own family and for a friend, etc.). To reduce the impact of such cases on the measurement, the new survey module develop by the ILO focuses the respondent’s attention on the beneficiaries of their assistance. It helps them recall specific activities (even if they are performed simultaneously with work for one’s own family).
This doesn’t solve all the problems and especially those related to the estimation of time volunteered in simultaneous activities. For this reason, the ILO is currently working on testing approaches to improve the measurement of volunteer work in time use surveys, in which volunteering performed simultaneously with work for one’s own family tends to be overlooked. I hope that the result of these tests will help improve the main survey module.
I hope I managed to answer your question. If not, please let me know.
