Neighborhood Boundaries (44 neighborhoods; Department of Planning)
Neighborhood clusters from the Department of Planning as of July 2012. This dataset divides the District into 44 neighborhood clusters.
Also we have DC Cluster to Census block and tract crosswalk files. Josh De La Rosa Says: "Some blocks and tracts split across clusters. In these instances, DC provides the cluster proportions. The assumption is that the distribution is even within each tract even though we know it is not. With that said, the block crosswalk contains less splits and therefore should be less prone to error."
