Market research is when you gather data about your targeted audience for a business. A great place to start is with U.S. Census data. The Census has a new website - data.census.gov - that has replaced American FactFinder. Check out this FAQ page for a quick overview of how to search on data.census.gov.
Trexler Library has gathered other helpful links and books on the Market Research section of our Business Help Guide including for local and small business data and demographic information.
If you have more questions, please ask a librarian at reference@desales.edu.
