Good Morning Mark,
Thank you for your question.
Business Analyst Web App/Community Analyst contains the current year (2017) updated business summary data.
We do carry three years of data (2015, 2016 & 2017) that can be purchased as stand-alone databases. Unfortunately we do not have data prior to 2015 available. Please feel free to contact me with any questions.
Regards, Alice Kavanagh
