Racial inequality affects nearly every subject of study, so you can find pertinent resources within discipline specific databases. For example, there is information about disparities in quality of healthcare in databases that focus on nursing and medicine like CINAHL Complete and Health & Medical Collection, or you can find articles on environmental justice within science focused databases like Agricultural & Environmental Science Database and Environment Complete.
Brainstorm some keywords that will help you find information on your topic. You may want to to use the BOOLEAN Operator AND to connect the topic of race to other keywords. For example, to find information about disparities in educational resources and outcomes, you could search an education focused database for "achievement gap" AND race. Don't forget to search for synonyms and and variations of phrases popular in the subject area. The thesaurus feature available in most databases can help you find the best terminology to use.
Some databases may use subject terms that are outdated or even problematic. While these keywords may not reflect the way we speak about these topics, their inclusion may be necessary to find all relevant information. For instance, including a search for "riots" in addition to "protests" provides additional results.
You can find articles in psychology and other social science focused databases that directly address race. Some of these rely on experiments and meta-analyses that can support your research.
Since they cover such broad subject areas, these multi-discipline databases contain information about race from popular and scholarly sources.
