NPD market level information enables subscribers to identify the strongest markets and opportunities for improving business.

Data is collected from individual retail locations of a panel of 69 industry-leading retailers for consumer electronics, information technology, mobile audio, and imaging.

The aggregation of individual stores provides significant coverage for making confident and insightful decisions.

To normalize comparisons between markets, market level data looks at category dollar sales for every million dollars in total annual consumer electronic sales in the market.

Larger markets, those with higher populations, will generally have larger absolute volume sales.
