This page contains descriptions of the attributes that are located on the nodes and edges of the dual graphs in this repository. The underlying data was gathered by the Census in 2010 and was originally associated to the census blocks. The MAUP package was used to assign the blocks to the larger units and then the values were aggregated, both in total as well as using the UR10 labelling on the blocks.
