Midwest City, with around 57,000 people, is a mix of middle class post-war housing and upscale newer housing, based largely around the sprawling Tinker Air Force Base. The eastern part of the city is home to generally newer housing additions built in the past two decades. City leaders have enjoyed success in reinventing their downtown area, and attracting numerous eateries and shops to the Town Center Plaza, a new shopping center along Interstate 40 anchored by Lowe's, Target, and J.C. Penney locations. The city's former mall, Heritage Park, is left with two anchors – Sears and LifeChurch.TV in the former Dillard's space which closed in March 2006. The now closed mall interior area is being marketed as a separate potential big box retail shopping space.
