VBI Synthetic Populations

RTI Synthetic Populations

RTI  previously developed synthesized agent databases of human and livestock populations in suort of MIDAS. 

2010 U.S. Synthetic Population Version 1

Updated May, 2014. RTI has completed and released a new version of the U.S. synthetic population that uses the 2010 Decennial census and the 2007-2011 American Community Survey (ACS) as its sources of population counts and characteristics. The database contains geographically located synthetic households and household residents for the United States. This version also uses the Integrated Climate and Land Use System (ICLUS) gridded population dataset to place households across the landscape. As with past synthetic populations, students are assigned to schools, workers are assigned to workplaces and group quarters locations and residents are included. The 2010 U.S. Synthetic Population Ver. 1 QuickStart guide  contains additional information about new data sources and processing used to develop the data. The 2010 U.S. Synthetic Population Ver. 1 data can be downloaded by state or county from the download section on this page. 

U.S. Poultry Farms

RTI has also completed a synthesized poultry farm database containing synthetically generated and located poultry farms attributed with type of poultry (e.g. broiler, fryer, pullet, etc.) and counts (ranges) of birds on each farm. Preliminary papers describing the synthesized poultry farm data and data development methods are available from 2008 ESRI Federal User Conference paper and RTI's presentation at the ESRI Federal Users Conference 2008. The 2002 Census of Agriculture poultry farm counts were the basis for the number of farms synthesized.

U.S. Swine Farms

RTI has completed a synthesized swine farm database containing synthetically generated and located swine farms attributed with counts (ranges) of swine on each farm. This initial version was created using the same suitability surface that was used for the synthetic poultry as they have many similar factors that affect their placement. Preliminary papers describing the synthesized poultry farm data and data development methods are available from 2008 ESRI Federal User Conference paper and RTI's presentation at the ESRI Federal Users Conference 2008.The 2007 Census of Agriculture swine farm counts were the basis for the number of farms synthesized. A simple data dictionary is here: Synthetic Swine Data Dictionary. 

2010 Version 1 U.S. Synthesized Population Downloads

The 2010 U.S. Synthesized Population data can be downloaded directly by state or county. Each data package (either entire states or entire counties) are delivered as a set of compressed ASCII files. The links below allow you to download these compressed ASCII file packages. The Quick Start Guide describes the contents and structure of each file in each dataset.

Please see the Quick Start Guide or the metadata file that accompanies each download for information on how to properly cite these data in publications and research reports.

Synthetic Poultry Farms

The U.S. synthesized poultry farm dataset is also available for download. The data are available in ESRI shapefile format at the links below.

*some browser/O.S. combinations will create a file extension of '.tar.tar' when uncompressing the '.tar.gz' files. If this occurs, just rename the '.tar.tar' file to '.tar' prior to untarring.

Synthetic Swine Farms

The U.S. synthesized swine (hog) farm dataset is also available for download. The data are available in ESRI shapefile format at the link below.
