What type of research uses compiled data from the US Census Bureau and other public sources to provide market insights?

The correct answer is secondary research because it involves the use of existing data that has already been collected and published by other sources. In this case, data retrieved from the US Census Bureau and various public sources falls into this category. Secondary research allows marketers to analyze trends, demographics, and other market insights without the need to gather primary data through direct surveys or experiments. It is often more cost-effective and time-efficient, as it leverages available information to support decision-making processes.

Primary research, in contrast, entails the collection of new data specifically for the purpose of addressing a research question and typically includes methods like surveys or interviews. Qualitative research focuses on understanding subjective experiences and interactions, often through methods such as focus groups, and does not rely on numerical data. Quantitative research, while it involves gathering statistical data, is still considered primary if it collects new data rather than analyzing existing findings.
