The Consumer Panel Data comprise a representative panel of households that continually provide information about their purchases in a longitudinal study in which panelists stay on as long as they continue to meet NielsenIQ's criteria. NielsenIQ consumer panelists use in-home scanners to record all of their purchases (from any outlet) intended for personal, in-home use. Consumers provide information about their households and what products they buy, as well as when and where they make purchases.

Years Available: Starting with 2004 and including annual updates.

Panel Size: 40,000–60,000 active panelists (varies by year), projectable to the total United States using household projection factors.

Panelists: Household demographic, geographic, and product ownership variables are included, as well as select demographics for the heads of household and other members.

• Demographic variables include household income range, size, composition, presence and age of children, marital status, type of residence, race, and Hispanic origin. Male and female heads of household also report age range, birth date, hours employed, education, and occupation. For other family members, birth date, employment, and relationship/sex are reported.
• Geographic variables include panelist zip code, FIPS state and county codes, region (East, Central, South, West), and Scantrack Market code (assigned by NielsenIQ, and called Syndicated Major Markets (SMM) starting in 2021).
• Product Ownership variables include kitchen appliances, TV items, and internet connection.

Products: From 2004 to 2020, all 10 NielsenIQ food and nonfood Departments (~1.4 million UPC codes). These Departments are dry grocery, frozen foods, dairy, deli, packaged meat, fresh produce, nonfood grocery, alcohol, general merchandise, and health and beauty aids.

Starting in 2021 data, NielsenIQ implemented a new Product Hierarchy structure. The original Product Hierarchy of Departments, Product Groups, and Product Modules has been phased out. For now, Product Module Codes will still be available to make the transition smoother.

Product Characteristics: All products include UPC code and description, brand, multipack, and size, as well as NielsenIQ codes for Department, Product Group, and Product Module. Some products contain additional characteristics (e.g., flavor). Starting in 2021 data, NielsenIQ expanded the number of additional product characteristics.

Purchases: Each shopping trip contains the date, retail chain code, retail channel, first three digits of store zip code, and total amount spent. For each product purchased, the UPC code, quantity, price, and any deals/coupons are recorded. Note that retailer names are not available.

Geographies: Entire United States, divided into 62 major markets.

Retail Channels: All retail channels—grocery, drug, mass merchandise, superstores, club stores, convenience, health, and others.

Retail Scanner Data consist of weekly pricing, volume, and store environment information generated by point-of-sale systems from more than 90 participating retail chains across all US markets.

Years Available: Starting with 2006 and including annual updates.

Store Demographics: Includes store chain code, channel type, and area location. Retailer names are masked to protect identity.

Weekly Product Data: For each UPC code, participating stores report units, price, price multiplier, baseline units, baseline price, feature indicator, and display indicator.

Products: Weekly product data for 2.6-4.5* million UPCs including food, nonfood grocery items, health and beauty aids, and select general merchandise aggregated into 1,100 product categories store environment variables (i.e., feature and display indicators) from a subset of stores. The 1,100 product categories are categorized into 125 product groups and 10 departments. The structure matches that of the consumer panel data. All private-label goods have a masked UPC to protect the identity of the retailers.

Starting in 2021 data, NielsenIQ implemented a new Product Hierarchy structure. The original Product Hierarchy of Departments, Product Groups, and Product Modules has been phased out. For now, Product Module Codes will still be available to make the transition smoother.

Product Characteristics: All products include UPC code and description, brand, multipack, and size, as well as NielsenIQ codes for department, product group, and product module. Some products contain additional characteristics (e.g., flavor).

Geographies: Scanner Data from 35,000-50,000* participating grocery, drug, mass merchandiser, and other stores, covering more than half the total sales volume of US grocery and drug stores and more than 30 percent of all US mass merchandiser sales volume. Data cover the entire United States, divided into 62 major markets, and include the same codes as those used in the consumer panel data.

Retail Channels: Food, drug, mass merchandise, convenience, and liquor.

*As of 2018, approximately 15,000 more stores have been added.

Complementary to the Consumer Panel data, this annual survey contains information about panelists’ ailments and shopping they experience during the time surveyed. Researchers must be subscribed to the Consumer Panel dataset to have access to these data, however, there are no additional fees required.

Years Available: Beginning in 2011 and including annual updates.

Panel Size: 40,000 - 62,000 active panelists (varies by year).

Types of Data: Survey questions vary by year, however the following are several categories of information included in this dataset.

Ailments and Diagnoses: Panelists report for themselves and/or other household members whether they have experienced different ailments and illnesses.

Complementary to the Consumer Panel Data, the Kilts Center offers data from two custom Panel Views surveys commissioned by academic researchers. These datasets contain additional information about households and their members. Researchers must have a subscription to the consumer panel dataset to receive access to these surveys. There is no additional cost for these data.

Tax Rebate:This survey tells about how households spent the 2008 Federal government tax rebate.

Tell Us More About You: These surveys, one from 2008 and the other from 2011, contain data about where household members were born, where they live now, additional information about education (e.g. college major), occupation, and purchase behavior in certain categories.
