Should be noted that GIS representations of precincts are not up to date any longer -RMF
Below are three GIS representations of Bellingham Precincts, Whatcom County Precincts (2011), and CVAP information and Block Groups (2012). This GIS data has been developed for three different agencies (City, County, Census), each of which have emphasized three different sets of information. Consequently, hybridizing precincts data with Block Group data is a difficult task. This is a shame since co-ordinated GIS could tell us in which precincts registered and non-registered voters live.
The City of Bellingham holds the most dense collection of precincts in Whatcom County. In total, the 68 200 series precincts hold almost 40% (49,632) of total registered voters. There may well be many more voters in these districts that have not registered. It would be nice to know where they are.:
Whatcom county currently has 177 precincts total, divided between the 119 in the 42nd LD and the 58 in the 40th LD. Although not as numerous as Bellingham, the small cities of Blaine, Everson, Lynden, Ferndale, Sumas and others have unique series of precinct numbers. The 28 small city precincts have 16% (20,789) of the current active voter list.
The map below of Whatcom County is non-geographical representation of Census "Block Groups" for which information is collected on demographic groups including total population and CVAP (Citizen Voting Age Population). This data allows us to see information like this (see complete list below):
GEOID CIT_EST CVAP_EST
1 530739400002 1490 1240
2 530739400001 3135 2195

4 530730110001 405 390

6 530730107022 1610 1215
7 530730107021 2080 1475
...
where GEOID in the Block Group (2012 data), CIT_EST is the estimated population, CVAP_EST is the estimated voting age population. :
Block Groups look like precincts, but they are definitely not. These block groups shape look like this. I have titled each block with CIT_EST, CVAP_EST, and Block Group Number:
A tremendous amount of electoral research could be done easily if each of these GIS sources were:
(1) kept up to date
(2) coordinated with similar data fields
(3) coordinated with housing/property based GIS systems.
More to come. Code is here. Annotated Block Group shapes are here.
