I have updated my race/ethnicity diversity blog posts to include the spreadsheet workbooks (large cities, 65,000+, Congressional Districts).
Also, I updated the spreadsheet workbooks for the Bay Area Congress blog post.
I use Apple Numbers as my spreadsheet software. I then export Excel files from Numbers. I hope this is of use!
