Have you seen all those commercials about the 2010 US Census? Unless you are living under a rock, you probably have. All of the data that is going to be collected will be a gold mine for the on-demand business owner. In Chapter 3 of the Business in Minutes book, market research for your business was outlined. Take a look at some of these links to various data sources at the homepage for Census.gov.
Thanks to the American taxpayers, all of this information is free to use by the public. This data is a great starting point for general market research. It will give you some broad ideas and hopefully point you in the right direction for your market study.
To learn more about all the market research you will need to do as well as other market research resources, pick up a copy of the book "Business in Minutes – How To Profit From the On-Demand Revolution” at CreateSpace, Amazon.com, or Barnes & Noble.com.
