go back up 1 page and you'll see your answer. The NPD Group offers comprehensive market research on consumer behavior and attitudes across a wide array of industry sectors. This insight is gleaned from over 3 million individuals who are registered participants in NPD’s consumer panel and have agreed to provide us with this information.
Through consumer tracking, NPD offers our clients a total market picture, encompassing activity at all retailers, including Walmart. Consumer tracking also delivers critical insights into market trends and demographics and customer satisfaction to drive strategic planning and tactical decision making, addressing issues such as: They are estimating walmart/sams based off of 3m participating consumers (who some might not even shop at walmart). You aren't linking us to the magical page that states they get numbers straight from walmart/sams. |

I know NPD does a general consumer sample. (I guess 3 million in size) and match it up vs their direct store esitmations to see how close the two are together. Guess this is part of that.
