Purpose Used for demographic analyses. Supplemental_Information Procedures_Used Data sets were created from SSCGIS sources at the tract, block group and block levels. We created new fields in each of these in order to produce unique identifiers for each feature, for example, creating a single field ctb in the block coverage /ise/wrb/blkpop which combined the county, tract, and block numbers. We also created new data fields by processing various of the original attributes, and also joined to these tables data from the summary tape files as appropriate to the level of spatial reporting unit of the summary data. An important issue in creating a population database for this project is that the hydraulic unit defining the study area, the Willamette River Basin, does not necessarily result in boundaries that are coincident with census reporting unit boundaries. Thus, census blocks may be split in two by the study area boundary. In some cases the study area boundary can wander in and out of a census block creating multiple fragments within the study area, while leaving, perhaps, the majority of the block outside; the reverse occurs as well, in which the block lies primarily within the study area, but the study area boundary splits it into multiple parts. Fragmentary polygons are produced at the study area edge by another phenomenon as well, differences in the locations of points in space due to the use of different sources and methods in the production of, for example, the hydrologic unit boundary, than of the census units. In this case both boundaries nominally do agree, but inevitable differences in how they are mapped produce usually small "sliver" polygons when they are combined. The initial result of a clipping operation on the census unit geometry is to leave each of the fragments of an original unit having all of the attribute values of the parent polygon - each reports the entire population count of the parent unit from which they arose. A summing of population from all of these units would overstate the total. Because the census blocks are the spatially smallest reporting units for population, they provided the highest spatial resolution with which 1990 population can be mapped. A series of fields were created in the blkpop coverage, but not in the block group and tract coverages, in order to address the two problems mentioned above: OLDAREA, AREADIFF, NAREADIFF, PRORFLAG, HU100P, POP100P. Together these fields were used to isolate sliver polygons, and for those remaining, a total of approximately 265 out of about 46,000, population was "pro-rated" on an area-weighted basis: The fraction of the area of the census block remaining in the study area was multiplied by the total population count for the block and that value placed in a new field called PRORPOP. For those census blocks not prorated, the original value for population count was transferred to the PRORPOP field. Thus, this field constitutes the adjusted population count for each census block or fraction of one contained in the study area. Although this approach minimized certain types of error created by spatial operations, it is clear that human population is not distributed evenly within a census block and that the treatment chosen here is simply the best use that can feasibly be made of the available data. Census block sizes, however, are small where population is dense, and large where density is low, thereby acheiving a rough normalization of population distribtuion within a block. Human population density is a value which is the same for a census block or any fraction of it and is not subject to the problems discussed above.
