Dollar Store entry has a bigger impact in rural markets than in urban ones

USDA ERS reporrts in Amber Waves under the headline, "Dollar Store Entry Affects Rural Grocery Stores More Than Urban":  

Independent grocery stores, or grocers whose owners operate fewer than four stores, have been a large part of the rural U.S. food retail landscape. In 2015, they represented about half of the food retailers in 44 percent of U.S. counties. Leading up to 2015, however, dollar stores were becoming increasingly visible in rural counties, experiencing the second-largest growth behind supercenters among food retailers from 1990 to 2015, according to research by USDA, Economic Research Service (ERS). Economists from ERS, North Dakota State University, and the University of Connecticut recently investigated the implications of the growth of dollar stores for more traditional, independent grocery stores using proprietary data from the National Establishment Time Series (NETS) database and the ERS Rural-Urban Commuting Area (RUCA) Codes.

NETS provides geographic, employment, and sales information for every year an establishment is open for all sectors of the U.S. economy. The researchers focused on dollar stores and independent grocery stores and combined these data with the ERS RUCA codes’ measures of population density, urbanization, and daily commuting to classify census tracts; in this research, all nonmetropolitan core or commuting areas were classified as rural.

The researchers examined what happened to the number of independent grocery stores, as well as employment and sales statistics from these stores, from 2000–19, when a new dollar store opened in the same rural or urban census tract. Results showed that when a dollar store opened in a census tract independent grocery retailers were 2.3 percent more likely, on average, to exit the market. Employment at independent grocery stores fell about 3.7 percent, and sales declined by 5.7 percent.

However, there was significant variation between the impact of dollar stores on independent grocery stores in urban and rural census tracts. For instance, the likelihood of an independent grocery store exiting a rural census tract after a new dollar store opened was 5 percent, about three times greater than in urban census tracts. Similarly, the decline in employment in rural tracts was about 2.5 times as large as in urban tracts, and the decline in sales was nearly double in rural census tracts.
