3rd Party Data is data that you purchase from 3rd parties or sources that did not collect that data themselves ? typically large data aggregators. Data aggregators buy 1st party content from a large list of companies, compile it, then sell it as 3rd Party Data. While 3rd Part Data can be beneficial in looking at a market from a 30,000 ft. view, it is not as helpful for in-depth research, since you don’t have access to the original source of the data.
