Once logged in, download data from:

https://www.socallinuxexpo.org/scale/22x/demographics.csv

But change 22x to the desired year.

Then run diversity_reports.rb on it and stick it in the spreadsheet:

diversity_reports.rb <file>

The get_reg_demo_stats.py can be run on the reg system to generate two CSVs: demo_data.csv and totals.csv. You can then run diversity_reports on that too:

diversity_reports.rb --input-type reg --totals-csv totals.csv demo_data.csv
