In order to accurately interpret the data included in Government at a Glance, readers need to be familiar with the following methodological considerations that cut across a number of indicators. As in previous editions, the standard format for the presentation of indicators is on two pages, except for a few indicators – such as indicators on the rule of law and on the quality of public services – that are presented on four pages. For the two‑page format, the first page contains text that explains the relevance of the topic and highlights some of the major differences observed across OECD countries. It is followed by a Methodology and definitions section, which describes the data sources and provides important information necessary to interpret the data. Closing the first page is the Further reading section, which lists useful background literature providing context to the data displayed. The second page showcases the data. These figures show current levels and, where possible, trends over time. A Glossary of the main definitions of the publication can be found in the final chapter of the book.
