It was digitized and attributed using the 15th Census of the U.S.: 1930 Population publication from the U.S. Dept. of Commerce, Bureau of the Census. This coverage shows the 1930 MCD boundaries and selected population characteristics of each polygon. Purpose This coverage is intended as a thematic data layer showing the boundaries of the MCDs in 1930. This map is displayed in the Willamette River Basin Planning Atlas (PNW-ERC, 1998). Supplemental_Information Procedures_Used 1930 Census data was entered to create a DBF file. This file includes MCD precinct name and population. (MCD_CODE was added later). The polygonal geometry was digitized from the 1930 Oregon MCD map published by the U.S. Bureau of the Census in 1932. 1.) scan section of map that applies to WRB. 2.) clean up image using Photoshop 3.) IMAGEGRID 4.) GRIDLINE 5.) screen digitize over dashed lines using ArcInfo. 6.) after digitized, topology is established. This function creates unique identities for each polygon. 7.) map is tested for polygon errors through an internal editing function and a clean coverage is created with no dangles. linework is checked. 8.) georeference coverage to UTM coordinates. a.) add identifyable tics that can be referenced to known coverages (counties, rivers, cities)...coverage must be populated with as many tics as possible and spaced relatively even across the coverage. (55 tics were added) b.) UPDATE coordinates of added tics to equal that of known coverages c.) TRANSFORM digitized coverage d.) rubbersheet coverage by ADDing links and using ADJUST. (may need to be repeated until coverage is as close as possible). 9.) attribute polygons with MCD_CODE 10.) link geometry to tabular data using ArcView 11.) calculate population density a.) AREA (sq.meters) / 1,000,000 = sq.kilometers b.) AREA (sq.km.) x 0.386102158496 = sq.miles c.) POPULATION / AREA (sq.miles) Revisions 1 Reviews_Applied_to_Data Cartographic products were reviewed by two in-house teams, and by an outside panel of experts convened by the EPA.

References_Cited U.S. Dept. of Commerce. 1932. 15th Census of the U.S.: 1930 Population. Vol. III. Pt. 2. U.S. Govt. Printing Office, Washington D.C.. Notes Population density was calculated first, then the coverage was clipped to the WRB boundary. This means that the population density calculation for any MCD that extends beyond the WRB boundary shows the pop. den. of the entire MCD. In cases where cities are only represented by a small circle on the map (no geometry available) the population for that city was added to the surrounding precinct when making the population density calculations. In cases where several polygons make up a single precinct, the POPULATION and POP_DEN fields are reported as the value for the entire precinct in all included polygons.

Completeness_Report Positional_Accuracy Horizontal_Positional_Accuracy Horizontal_Positional_Accuracy_Report: The original manuscript provided no information as to the map projection used, and no accuracy information. In transfering it to digital form, few contemporaneous control points were available, and modern county boundaries were primarily used instead. An extensive and repeated process of linking digitized features to presumed modern correlates was used to adjust the digitized manuscript until no improvement in average error was achievable. Sampled locations indicate an average horizontal position disagreement with modern locations of approximately 500 m, with some as high as one kilometer.

The codes listed in this attribute are explained in the supporting table: MCD_CODE. (See section 7). COUNTY was added to make it easier to determine which county the MCDs belong to. PRECINCT was added when the spatial data-set was joined to the tabular data. This field is the name of the MCD precinct. POPULATION was added when the spatial data-set was joined to the tabular data. In cases where several polygons make up one precinct, the population value is the same for the individual polygons of one precinct. POP_DEN was derived from transforming the AREA (sq. meters) to area in sq. miles, then dividing it into the total population of each MCD. This field is reported in person/sq.mi.
