Updated--New Map, Oregon Census Tract Diversity Index Values and More.

Update: I am in process of modifying the embedded map to show variations on the 2010 Diversity Index. Goal is to get Census tracts with values less than statewide average displayed with light red fill; those will values up to 50 are shown in light green, and those with values above 50 are shown in a brighter green. One completed this will confirm the ability to display on web maps customized variations in topical data with different fill colors, using free Google Fusion and Google Mapping software. I will do a second update once I am satisfied with the way variations are displayed, right now it's a work in progress.

As another Fair Housing Month project I have embedded below a Google Map which has select population and housing data for ALL Oregon Census Tracts. Included are the Diversity Index values for both 2000 and 2010, the percentage change in the Diversity Index, population, the Hispanic population, and the housing vacancy rate.  (The link HERE should also open this map in Google Fusion; although I have made the data files and map public you might need a Google account to open?).

Map was created in Google Fusion by merging SHAPE files for Census Tract geography and the Diversity Index values I had previously calculated for each census tracts.

Navigate and zoom in to the area of choice and click it with a mouse, and the available data for that census tract will appear. 

Data visualization could include current or future Census 2010 data, or data from any data table that includes a Census Tract geo or other geo code. (Think voucher counts, LIHTC unit counts, poverty rates, food stamp recipients, free or reduced price school lunches etc). 

If you know of other Oregon based Google Fusion maps of interest please add a comment with a link to the map or website.
