Where can I find a breakdown by race and gender of US CS bachelor's degrees?
the Taulbee report An-In Depth Examination of Data and 
Trends Regarding Women in Computing provides summary data on computing degrees by ethnicity &amp; gender for 2013 in Table 2 on pg 20 and cites the Integrated Postsecondary Education Data System (IPEDS) as their data source. You can either filter through their data online or download it:


  Data are available starting with the 1980-81 collection year for the Complete data files and Custom data files functions, which zip the data into comma separated value (*csv). Beginning with the 2010-11 collection year, data for each collection year are compiled into an Access database.


Some tips for using their online data statistics:


Try using the 'Statistical Tables' option on the 'Use the Data' page
When select institutions, if you select 'By variables', there's an entry called 'Completions' which has an option for reporting 'Number of students receiving awards/degrees, by race/ethnicity and gender'
After that, select the specific gender/ethnicity info you're filtering for
