The article presents volunteering in Hungary in the 2010s based on measurement recommendations and experiences that are suitable for assessing the extent of volunteering worldwide and for international comparison In accordance with the recommendations of the methodological manual on measuring volunteering developed by the International Labour Organization and Johns Hopkins University, the Central Statistical Office conducted additional surveys in 2011, 2014, 2017 and 2019 entitled "Volunteering" in connection with the Labour Force Survey based on the population interview. This included, in addition to the demographic characteristics of volunteers, a picture of both formal and informal volunteer activity areas, the hours they volunteer, the range of beneficiaries, and other characteristics of volunteering, such as motivation. Besides the additional survey data, we also publish estimated equivalent headcount data and estimated value data based on the time spent on volunteering. The estimates are primarily designed to quantify the extent to which volunteering in Hungary has contributed to the country's economic and social performance. In addition to the similarities in data collection methodology, the unchanged methods of estimating hours and values ensured that the results were fully comparable. The complementary modules showed that a significant proportion of the adult Hungarian population - one third - had volunteered in the 12 months preceding the survey, and that the benefits of volunteering to society as a whole and to individuals, in terms of the monetary value of the contribution to GDP, remained very significant.
