As a port city, Baltimore has always had a diverse population, as the home of deeply rooted African-American, Chinese, Greek, Polish, Italian, Catholic and Jewish communities, just to name a few. These groups helped give the city its renowned charm. Recent years have seen the demographics in many neighborhoods shift to include Hispanic, Korean, and Ethiopian communities. And while city residents have historically stayed in their neighborhoods or fields of work, a variety of social entrepreneurship groups including Open Society Institute-Baltimore and events such as BarCamp Baltimore aim to forge a greater understanding and sense of community in Baltimore.
