Sources & Methodology:
  • We define STEM (science, technology, engineering, and math) majors using the DHS STEM Designated Degree Program list. This list is based on the Classification of Instructional Programs (CIP) hierarchy defined by the National Center for Education Statistics. Use the UC Berkeley STEM Major tree explorer to see which majors Berkeley categorizes as science, technology, engineering, or math.
  • Peer comparison degrees awarded data comes from the National Center for Education Statistics' IPEDS database. Due to the number of variables that we're using, we download the IPEDS Access database rather than using the system's web interface. In that database, we pull data from the "Cyyyy_A" Completions table, filtering on bachelor's degrees. That table contains data on awarded degrees rather than unique recipients, so double majors are counted multiple times. Note that different institutions often assign different CIP codes to what might be very similar majors, which can affect whether those majors appear as STEM. In addition, the IPEDS data currently codes two Berkeley majors, Psychology and Geography, under incorrect CIP categories; we've given them the correct CIP values in this dashboard. All non-IPEDS data in this dashboard is available in Berkeley's data warehouse reporting system, Cal Answers.
  • The IPEDS dataset used for the two peer comparison charts in this dashboard has different ethnic categories than are used on campus, which make it somewhat difficult to determine underrepresented minorities. To do so, we're grouping the American Indian/Alaska Native, Black/African-American, Hispanic, and Two or More Races counts. We group Non-Hispanic, Asian, White, and Unknown into non-URM. International students fall into a separate category for which we do not collect ethnicity data, and so are not shown in the peer charts. All of the remaining dashboard pages use UC Berkeley's gender and ethnicity categories. When grouping by gender, the category "All Other Students" includes both men and students who decline to state a gender category. The "Underrepresented Minority" ethnicity category shown on the non-IPEDS pages includes students who self-identify as African-American, Chicanx/Latinx, or Native American/Alaska Native. The "Asian/Pacific Islander" ethnicity category includes students who self-identify as either Asian or Pacific Islander. The "International" category includes non-US citizens/non-permanent residents, who are not counted under specific ethnicities for federal reporting purposes. The "White/Other" ethnicity category includes students who self-identify as White or do not provide information. Prior to 2011, students could also specifically choose an "Other" ethnic category at Berkeley.
  • The STEM Pipeline charts utilize both undergraduate admissions and entering cohort data for the past 10 years, combining data for freshman and transfer entrants who intend, declare, or graduate with a STEM major. The charts show the percentage of STEM students who are women and underrepresented minorities at each point in the pipeline; the total count of students at each point becomes progressively smaller (e.g., we admit fewer students than apply, etc.).
  • Charts showing currently enrolled students use the most recent Fall or Spring student census, excluding visiting students and those who have not yet declared a major. Students who have both a STEM and a non-STEM major are counted under the STEM category in overall counts. Students with multiple STEM majors are counted once within each STEM field in the more detailed charts.
  • Charts showing degree data count awarded degrees (a single student can receive multiple degrees), prorated for multiple majors.
Notes on Other Available Data:
  • The National Center for Education Statistics (often referred to as "IPEDS," the name of their primary data collection program for postsecondary institutions) publishes data on awarded degrees by CIP category and gender. The completions counts that they produce will be slightly different than those we use on campus, due to retroactive adjustments that we may make as better data becomes available over time. As noted above, the IPEDS data currently codes two Berkeley majors, Psychology and Geography, under incorrect CIP categories; we've given them the correct CIP values in this dashboard.
  • The enrollment and degree data published on the UC Information Center website shows some of that data by "broad field of study." These fields don't necessarily correspond exactly to the STEM fields used in this dashboard.
  • In Fall 2017, the Office of Planning & Analysis posted a time-to-degree study, which included information about STEM majors. Note that this paper looked at degree recipients, rather than degrees awarded.
