The Manual on Statistics of International Trade in Services 2010 (MSITS 2010) provides an overarching statistical framework for compiling the data required for measurement of the international supply of services and elaborates the relationships among various components of that framework. The present Compiler's Guide accompanies that reference publication. Part I contains an overview of the conceptual framework (chapter1), the legal framework (chapter 2) and the institutional arrangements (chapter 3). Parts II and III focus on data sources and collection and data compilation. Part IV deals with cross-cutting issues.
