Provide a summary of important quality and methodology information about your article in a Data sources and quality section. This section should only be included in analysis articles, as it is unlikely that information articles will contain data. Using a standard heading for this section will create consistency for users and help identify articles from other content types, such as statistical bulletins.
Highlight any important information about the data source and collection method, as well as any caveats about the quality of the data. Use clear subheadings to break up the content and guide users through the information by topic. For example, use subheadings such as Data collection, Sample size, and Comparability with other sources.
Keep this section brief and link to any existing methodology information using clearly written link text rather than duplicating the content and increasing the word count for your article.
