The United States conducts a decennial census to establish population counts that influence voting districts and the allocation distribution of resources to state and local governments. The results of the decennial census will have long term effects in the distribution of federal and state funding. This importance is magnified in the current economic client. Based on the 2000 decenial Census, the US Census Bureau estimated approximately $300 billion in Federal funding directed to states and local governments are apportioned by census figures. This represents $1,000 per person per year coming to state and local government in North Carolina for each person counted in the Census. Conversely, each person missed as part of the Census tabulation represents a potential loss of $10,000 of federal funding for the upcoming decade.
In preparation for the upcoming 2010 Census, the North Carolina General Assembly provided resources for the North Carolina Center for Geographic Information and Analysis to work closely with the Governor’s Census Liaison in the Office of State Budget and Management to develop the North Carolina Master Address Dataset. The NC Master Address Dataset represents a compilation of the best available representation of situs addresses and their location. CGIA contacted county and municipal governments to acquire this information, and insight on how each local jurisdiction manages address assignment and maintenance.
Aside from developing a dataset suitable supporting the upcoming 2010 Census, the project has developed a comprehensive and flexible workflow for ingesting and managing address-related data. The process has been specifically designed to be adaptable for meeting business requirements of state and local agencies. Documented business requirements can be integrated from a stakeholder into the appropriate processing steps throughout the workflow to generate custom output products suitable for existing applications. This workflow development also supported the development of automation tools to streamline initial processing. For future iterations and updates, these tools will provide a foundation for automating significant portions for the ingest and standardization of source data. The NC Master Address Dataset is built on recognized and emerging standards for easy adoption and maintenance in the future.
CGIA delivered the NC Master Address Dataset final report
for the project to the Office of State Budget and Management and North Carolina State Data Center on June 26, 2009.
The NC Master Address Dataset products are available in the Census Master Address File (MAF) file format (a pipe delimited ASCII file) and as shapefile in a GIS-ready form. The state has been broken into ten regions to accommodate the volume of data.
Note: The 2009 Master Address dataset can be found in NC OneMap Geospatial Portal.
