Note from professor Brendan O'Flaherty: Notice that it has no source; it's just what some church people think is going on. That would be ok if there were no other source of data. But the 1910 census was a pretty good job, and includes both first and second generation. And for the really ambitious, the manuscript census data is available and digitized and somebody could produce a house-by-house map. From the 1910 census, I can see some errors in the beloved 1911 map. The most obvious is in the location of the African American population. It correctly shows large numbers of African Americans in the 2nd and 4th wards, but misses the large numbers in the 3rd and 7th wards, especially. The 7th ward had the second largest number of African Americans in 1910, after the 2nd ward. In the Ironbound, it misses the large Irish population of the 5th ward. It also misses the large Italian populations in the 14th and 10th wards. The Chinese presence is exaggerated in the 4th ward. There were 100 persons who were "Indian Chinese and Japanese" in that ward, slightly less than the number of people born in Scotland. And of course, the map doesn't include Vailsburg. I think Newark was much less segregated than this map indicates, but since the manuscript census is available now, there is no sense speculating about that.
