The map is clearly that of New York, but not as I have ever seen it before.  Cartographer Eric Fischer has taken a technique called “dot mapping” to illuminate the integration – or singular lack of it – in a number of US cities, using information gleaned from the 2000 census.  He has then plotted it by the declaration of race for each address.  Each dot represents 25 individuals and he has used the following colours.  Red is for Whites, blue for Blacks, green is Asians, orange is Hispanic and gray is other.


Detroit shows its infamous black/white boundaries with a clear separating along the Eight Mile beltway that is astonishing.

 The east / west divide in DC is also clearly shown.

Consensus might have made one think that the cities with the greatest segregation would be those in the South.  The maps however show segregation and racial division rife in the enlightened north east, and liberal west.  San Antonio in Texas seems to be far more integrated and there Whites and Hispanics blur and no clear rich enclave is seen.

It’s well worth taking the time to visit Fisher’s excellent maps where dozens of cities have been given the treatment.
