The document discusses the Atlanta-Sandy Springs-Marietta metropolitan statistical area (MSA). It notes that the MSA had a population of nearly 5.6 million in 2015 and is home to over 138,000 businesses. Major economic generators in the region include diversified business sectors, higher education, government, arts/entertainment, conventions/tourism, and healthcare. Approximately 80% of the region's job growth between the early 1990s occurred in the "favored quarter" area, while over half of population growth was outside this area, leading to increased traffic congestion. The region experiences major costs and impacts from traffic congestion.
