Trendlens icons-Demand IndexBETHESDA, Md. – January 22, 2024 – The Auto Care Association today announced the release of five new product lines, as well as the addition of a new leading-edge Annual Unit Volumes metric that are now available for 25 product groups in Demand Index. The Demand Index, housed on the Auto Care TrendLens™ platform, helps aftermarket companies know how their products are performing against the market with the only tool that provides hard part and other parts performance data from point of sales transactions.

Get true market share with Annual Unit Volumes
With this update, Demand Index users can now see how many units of these products were sold for the calendar year, providing true market share value. This data is available yearly at the national level. Users can expect more Annual Unit Volumes for Demand Index product groups to be released monthly.

The most powerful measurement of market share
In addition, an innovative new metric is also available: the “Rest of the Market” data view is available for product groups that have Annual Unit Volumes released. This data will be published simultaneously with the units, segmented by region, and will be readily available on a monthly basis. This new update is exclusively available to Demand Index data contributors and their suppliers as long as they are Demand Index subscribers.
