As a port city, Baltimore has always had a diverse population, as the home of long-standing  African-American, Chinese, Greek, Polish, Italian,  Catholic and Jewish communities 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 the city residents have historically stayed in their neighborhoods or field of work, a variety of social entrepreneur, groups including Open Society and events such as BarCamp Baltimore, are trying to forge a greater understanding and sense of community in Baltimore..
