From Samples to Global Estimates: Extrapolation Methodology
In order to develop estimates of the global scale of organization-based and direct volunteering and its variation among countries at different levels of economic development, it is necessary to blow up our sample to the global population of countries using a common technique known as extrapolation. Because of the nature of the underlying data, we had to deploy two separate extrapolation techniques: one for the organization-based volunteering data generated on 43 countries through our CNP project; and the other for our direct volunteering data generated through our assembly of TUS results for 33 countries. The first data source is used to estimate volunteering through organizations, while the second to estimate direct volunteering.
Our methodology for estimating volunteering through organizations takes advantage of the data on the NPI workforce in 43 countries assembled by the Johns Hopkins Comparative Nonprofit Sector Project (CNP). For the 43 countries in the CNP data set, we used the actual volunteer shares of EAP reported in Table 2.1 to estimate the actual number of FTE volunteers. These 43 countries on which we have actual observations account for nearly 59 % of the total estimated number of FTE volunteers globally. For the remaining countries, we used a two-step process that made use of a linear least square regression model derived from data on these 43 countries to estimate the aggregate size of the organizational volunteer workforce in the remaining 139 countries of the world not covered by the CNP.
