The past two weeks have seen yet another – brouhaha? kerfuffle? debacle? – over issues of inclusion, diversity, and equity in the mathematical sciences. If you would like to catch up on this, see here and here and here (in that order). If you are not in the mathematical sciences, and even more broadly, if you are not in academia, this might seem like inside-baseball-type stuff. It’s not. **Diversity in mathematics matters for everyone in this country.** And even more specifically, diversity of *faculty* in the mathematical sciences matters. To understand why, let’s put the following five facts together.

###### Fact #1: The U.S. has a STEM Labor shortage

In 2012, the President’s Council of Advisors on Science and Technology (PCAST) released a report called *Engage to Excel: Producing One Million Additional College Graduates with Degrees in Science, Technology, Engineering, and Mathematics *(STEM). The title of the report says it all: the U.S. faces a severe STEM labor shortage. I encourage you to peruse this fascinating and scary report.

###### Fact #2: The STEM Labor shortage is bad for our country

The PCAST report explains:

*Economic projections point to a need for approximately 1 million more STEM professionals than the U.S. will produce at the current rate over the next decade if the country is to retain its historical preeminence in science and technology. Retaining more students in STEM majors is the lowest cost, fastest policy option to providing the STEM professionals that the nation needs for economic and societal wellbeing.*

###### Fact #3: minoritized groups could play a key role in addressing the STEM labor shortage, and hence, in our national well-being

Fast forward seven years from the PCAST report. This year, in 2019, the National Academy of Sciences’ (NAS) report *Minority Serving Institutions: America’s Underutilized Resource for Strengthening the STEM Workforce* states:

*A clear takeaway from the projected demographic profile of the nation is that the educational outcomes and STEM readiness of students of color will have direct implications on America’s economic growth, national security, and global prosperity. Accordingly, there is an urgent national need to develop strategies to substantially increase the postsecondary and STEM degree attainment rates of Hispanic, African American, American Indian, Alaska Native, and underrepresented Asian American students.*

###### Fact #4: Mathematics plays a special role within STEM

While the PCAST report address a labor shortage across all STEM disciplines, it specifically calls out the key role of the mathematical sciences. In fact, the report makes five high-level recommendations, and only one of them is discipline-specific: “Launch a national experiment in postsecondary mathematics education to address the math preparation gap.” Why would the PCAST report call out the mathematical sciences? The reasons are well-explicated in *The Mathematical Sciences in 2025*, published by the National Academies in 2013. A key finding of this report is:

*Mathematical sciences work is becoming an increasingly integral and essential component of a growing array of areas of investigation in biology, medicine, social sciences, business, advanced design, climate, finance, advanced materials, and many more. This work involves the integration of mathematics, statistics, and computation in the broadest sense and the interplay of these areas with areas of potential application. All of these activities are crucial to economic growth, national competitiveness, and national security.*

###### FACT #5: Diversifying the U.S. postsecondary mathematics faculty would bolster the mathematics training of minoritized individuals

Here, we draw on well-established results from the social sciences. Humans compare themselves to reference groups, and these comparisons play a key role in each individual’s psychological growth and self-concept. This is the so-called *role model effect*. One way to understand the role model effect is through the idea of *possible selves* as described in this seminal paper, cited over 8,000 times. For concreteness, let’s restrict our attention to career choices in young people. An individual creates a mental list of possible future careers. Then the individual looks at people currently working in those careers. If none of the people working in a particular career hold identities shared with the individual along axes that the individual values, then the individual’s belief in the viability of that career choice is diminished.

###### Putting it all together

I’ve given you five facts, supported by reports from the highest levels of science and government and by highly-cited peer reviewed research. The U.S. has a STEM labor shortage. This shortage is bad for our country. Increasing the participation of minoritized groups in STEM would go a long way towards fixing this problem. Within STEM fields, the mathematical sciences play a key role. And finally, in order to persist in a field, students look to role models. Therefore, **a diverse postsecondary mathematics faculty is important to our national wellbeing.**

###### We seem to have no idea how many faculty of color there are in the mathematical sciences.

The American Mathematical Society keeps statistics on gender at every level of the academic mathematical sciences, and they appear to keep statistics on participation of people of color at the doctoral degree level. You can find statistics on participation of people of color in all STEM fields and at all degree levels through the National Center for Science and Engineering Statistics.

What seems to be missing is data on faculty of color within the mathematical sciences. It is possible that some of this data is captured in the work of UCLA’s Higher Education Research Institute. It is hard to say because their publicly available report doesn’t contain this information by field, and because their full data appears to be proprietary. Furthermore, after asking around quite a lot recently, no one within the mathematical sciences has been able to point me to statistics on faculty of color.

I am surely not the first person to notice that we are missing these data, but I myself have only just become aware of the lacuna. This hole in our knowledge is a serious barrier to increasing representation of minoritized individuals in STEM, and giving our country a brighter future.
