A picture of a popular secondary market research source: library.

Market research is vital for successful marketing. It helps you understand consumer needs, motivations, preferences, market trends, and the competition. Market research also provides valuable insights that allow you to make informed decisions about product development, marketing, and other key business processes.

Large corporations are privileged in the sense that they have the budget for primary market research to get answers to specific questions. Smaller businesses usually don’t enjoy this benefit and need to gather knowledge through other means. Secondary market research is a common and effective alternative to primary research that can deliver remarkable return on investment if done right — making it an essential component in the toolkits of startups and small businesses.

In this article, you will find a curated list of reliable secondary market research sources. To make it more accessible, I have broken the sources down into several categories and added short explanations of what sort of data you will find at each source. Whether you are a small business owner or a marketer, these secondary data sources will provide you with useful insights and help you make informed business decisions.

Government agencies

Data from government agencies is widely available and often free. You can trust these sources because data is handled by impartial and highly skilled professionals. They provide a broad, historical perspective on market trends and economic conditions, making them a valuable resource for informed decision-making.

I recommend using data from governmental agencies when researching macroeconomic factors such as population demographics, consumer spending, employment trends, education enrollment, and welfare — to name a few examples.

#1 U.S. Census Bureau

Data on population, demographics, income, housing, consumer spending, consumer confidence, and retail sales.

They also cite previous relevant work, supplying you with additional data points to enrich your research. Peer-reviewing is a key component of the publishing process, ensuring that articles are both reliable and valid outside laboratory settings.

However, you shouldn’t take that at face value. There are many low-quality journals with poor peer-review policies. I’d suggest sticking to the top journals in their field.

Likewise, some authors tend to exaggerate their findings in their interpretations, making familiarity with statistics and market research methods required to objectively evaluate the findings.
