Success in business is often based on complete and accurate information. Data can help you to make plans on what customers are out there, who they are and how much money they have that might be used to buy your products.
To determine what information is useful, there are two main questions that need to be answered. How can you guaranty that the information is accurate? As well, how much will it cost?
Census information is a good place to start. It is collected by the government. Its accuracy is unquestioned as it forms the basis of governmental decisions and laws. Better yet, it’s freely available.
You can get access to a trove of population, gender, ethnicity, and basic business sales facts at http://quickfacts.census.gov/qfd/. In their words, “QuickFacts includes statistics for all states and counties, and for cities and towns with more than 5,000 people”.
