The southern and eastern parts of the district include the more modest neighborhoods of the city, which is home to Amtrak's largest repair yard. Since the late 1990s, there has been an influx of Mexican and Hispanic workers to the district, which has further increased its Democratic leanings. Also, as the industrial and financial center of Indiana, the district has been strongly influenced by the politics of the unions in the past; however, their influence over the district has become increasingly marginal in recent years.
