Variable General Info
LULC weight ?Comment:The values of this variable are determined by the LULC class variable. The LULC weight was designed to recognize general differences in population density between different NLCD landcover classes, providing the deallocation strategy a capacity to better reflect the variation in population density at the IDU level. These LULC population weights are subjective; however, their development was primarily based upon the NLCD LULC class descriptions available at http://www.mrlc.gov/nlcd_definitions.php . Used to compute IDU level initial population. |
