Those affluent households are also making more trips to the grocery, accounting for the largest share (41%) of total basket ring dollars versus middle-income and low-income households. For the past 13 periods, affluent households posted trip growth in every period, while grocery trips by middle-income households were about flat and grocery trips among low-income households were off in all periods.

Affluent households are also driving faster trip growth in value retail channels like supercenters, warehouse clubs and dollar stores, but their overall importance to the sales in each channel ranges from a low of 19% for dollar stores to a high of 57% for warehouse clubs. “We see opportunity to use different assortment, pricing and promotional programs targeted to the ’shopper income’ draw of a particular store. And while value messaging needs to be prominent in these tough times, it can’t all be about low prices,” says Todd Hale, Senior Vice President, Consumer and Shopper Insight.

On a dollar volume basis, grocery stores continue to capture the highest percentage of consumer dollars, with 33.1 percent.  In Grand Rapids, Michigan, groceries capture almost 50 percent of the consumer spend, while in New Orleans grocery stores account for just over 20 percent.

Dollar Volume By Channel

Warehouse club stores are a major force in Western states, with the greatest percentage of consumer spend in San Francisco and Seattle.  In fact, of the top 10 markets for warehouse club store sales, nine are located in the west.  Meanwhile, warehouse clubs have the lowest percentage of share in Louisville and Columbus.  Across the U.S., drug stores capture about 3.8 percent of consumer spending, but in Cleveland, they make up almost 9 percent, while in Denver, they make up less than 2 percent.

Club stores skew to high-income households, while dollar stores, supercenters and drug stores attract a greater percentage of sales from lower income households.  Household has kids are more likely to spend their money at mass merchandisers, super centers and club stores.

The top three categories skewing to high income households are wine, diet aids and floral/gardening, while large households are buying disposable diapers, baby food and frozen juices and drinks. Seniors skew toward vitamins, medications/remedies and canned fruit, and households with teens skew towards sanitary protection, ethnic health and beauty products and gum.

In the last year, most channel penetration trends remained stable.  Supercenters saw the greatest increase, 2.4 percent on a year-to-year basis, while mass merchandisers saw the greatest decline, with a 2.9 percent loss. More interesting is a look at how channel trends have changed over the last 12 years:

“As consumers change their spending habits, both retailers and manufacturers are finding growth and profit opportunities by adapting their merchandising strategies to the changing retail landscape,” said Tom Pirovano, Director, Industry Insights at Nielsen.

Other subjects examined in Nielsen’s report were:

• Other channels (e.g., apparel stores, home improvement, electronics) and their average spend per trip
• Categories with the broadest appeal across demographics
• Categories with the highest buying rates and purchase frequencies
• Categories with the highest percentages sold with manufacturer coupons
• Food and beverage sales outside the traditional grocery channel

“While many retailers will likely scale back expansion plans in 2009 and 2010, aggressive and forward-looking retailers will use this time to test new formats and look for opportunities to expand in existing and new markets as weaker retailers close their doors or put themselves up for sale.  Americans will continue to look to stretch their dollars further given the current economic uncertainty, creating larger markets for discount retailers and grocers alike.  At the same time, we expect to see continued contraction among electronics, toy retailers and other discretionary retailers,” said Todd Hale, Senior Vice President of Consumer & Shopper Insights at Nielsen.

Since 2001, value and convenience stores increased store count by the largest percentages.  But that trend is not likely to continue.  Since the end of 2007, the number of convenience stores declined by more than 1,400.  Additionally, the number of toy stores has declined by 60% over the eight year period (from 2,458 to 999).  Electronics stores dropped by 5%, and with the recent announcement from Circuit City that it will liquidate all of their 567 stores, that retail format will likely continue to decline.

On a more positive note, several retail channels showed solid growth:

• Warehouse Clubs
• Supercenters
• Dollar stores

Additionally, pet stores, book stores, office supply, hardware/home improvement and liquor stores all posted growth as well.

Walmart and Target led expansion over grocers, which expanded more slowly and in different ways, such as opening new, smaller formats.

The niche grocery segment has shown tremendous growth, with expansion from high-end (Whole Foods and Trader Joe’s) and low-end (Aldi and Save-A-Lot).  Aldi, the deep-discount German grocery chain is looking to add 75 stores in the US in 2009, and its sales grew 21% to $7 billion in 2008.  Aldi and Save-A-Lot, which has also expanded during the eight-year period in question, offer budget-conscious consumers extreme value across a reduced assortment set with strong emphasis on store brands.

In the drug store segment, Nielsen finds rapid new store openings as well as acquisitions from three big chains.  Walgreens opened or acquired 2,952 stores between 2001 and 2008, while CVS expanded by 2,158 stores and Rite Aid expanded by an additional 1,316 locations.  CVS will get another boost in store count when they close the deal to acquire Longs Drugstores.  Warehouse stores also continued to be popular, with BJ’s, Costco and Sam’s all showing significant growth.

Perhaps the most interesting finding of Nielsen’s research is the tremendous growth within the Dollar channel.  While Walmart corporate opened up 1,025 stores between 2001 and 2008, the five leading dollar store chains opened 8,291 locations during the same period.  Companies like Dollar General, Family Dollar and Dollar Tree opened thousands of stores each.  And in the process, some of the companies, notably Dollar General and Family Dollar, have evolved to offering more mainline brands than in the past to position themselves as a destination trip among their core shoppers.

Record high fuel prices, soaring commodities costs, and declining consumer confidence have changed the way U.S. consumers shop, according to a recent Nielsen consumer survey.  

Results from the survey indicate that 63% of U.S. consumers have reduced their household spending this year. 

The findings also suggest that consumers will continue to combine shopping trips, eat at home, and seek out at-home entertainment.

Of those surveyed by Nielsen, 78% said they are combining shopping trips and errands — a 10% increase over last year.  Fifty-two percent of respondents reported eating out less — up 14% over last year, while 51% said they are opting to stay home more often — up 12% over last year.

Retailers and manufacturers serving lower income consumers are likely to feel the greatest impact, as these households make more drastic spending reductions. 

In contrast, private label products and low-priced branded products may actually benefit from consumers’ cost-cutting initiatives.  According to Nielsen’s survey, 35% of consumers plan to buy less expensive grocery brands — up 16% over a year ago. 

Online retailers, electronic stores, supercenters, warehouse clubs, dollar stores, and liquor stores all showed an increased number of trips in 2008, as shoppers sought out a mix of value, variety, and convenience.
