Re: "rather odd blank spots on a closely zoomed-in view"... > The locations of the dots do not represent actual addresses. The most detailed geographic identifier in Census Bureau data is the census block. Individual dots are randomly located within a particular census block to match aggregate population totals for that block. As a result, dots in some census blocks may be located in the middle of parks, cemeteries, lakes, or other clearly non-residential areas within that census block. No greater geographic resolution for the 2010 Census data is publicly available (and for good reason). http://www.coopercenter.org/demographics/Racial-Dot-Map#parks http://www.coopercenter.org/demographics/Racial-Dot-Map#park...
