    dct:description """This data set represents the average population density, in number of people per square kilometer 
multiplied by 10 for the year 2000, compiled for every MRB_E2RF1 catchment of selected Major 
River Basins (MRBs, Crawford and others, 2006). The source data set is the 2000 Population 
Density by Block Group for the Conterminous United States (Hitt, 2003).
		
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection 
Agency's (USEPA) RF1_2 and include enhancements to support national and regional-scale 
surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011).
		
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering 
covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the 
Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the 
Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and 
the Great basin (MRB6), the Pacific Northwest (MRB7) river basins, and California (MRB8).""" ;
