Binder and Reimers “An Ethnic and Racial History of New York City” goes in depth with all the various immigrants that migrated from Europe and China. They describe the various trades that the different ethnicities were skilled in (although the newer immigrants were much lower skilled than those before them), various churches which divided the Germans versus the Jews versus the Catholics and institutions which were born due to the divisions amongst the ethnicities.
If I were to create a website based on Binder and Reimers information then I would divide the website into the different immigrant groups that migrated to New York (Germans, Irish, Poles, Russians, Italians, Chinese, Syrians and the various Jewish groups). When you click on one of the groups on the homepage then it would link you to a map where it would show where these people were concentrated. For example, before the African-Americans were known to dominate Harlem, the Jewish were actually the dominant group that pre-existed before the African-Americans. Also, the map would show the institutions created by the group such as the Germans who owned their own hospital that tended to only Germans and how it was helpful to their people. My website would also show the population of the immigrants in certain areas of NYC and greater NYC (i.e, Brooklyn) as well as the amount of immigrants which migrated from other countries during various peak times. It would also show the trades certain groupes entered such as the Bohemians who labored as metal workersand garments but were exceptionally skilled in the tobacco trades (esp. the women). The point of the website would be to deliver summaries of the groups and to show how the groups spread throughout the city and established in different areas.
