Washington — Target, Walmart and McKesson were each recognized Friday as one of America’s more community-minded companies as part of the The Civic 50 — the first scientific evaluation to rank the companies that best use their time, talent and resources to improve the quality of life where they do business. 

The survey was conducted by the National Conference on Citizenship and Points of Light, and was published in the Nov. 9 issue of Bloomberg Businessweek.
