Biostatisticians are specialized statisticians who analyze biological and health-related data to advance medical research and public health initiatives. With a median salary of $104,350 and 8% job growth projected through 2034, this field offers strong career prospects for those with advanced degrees in statistics, biostatistics, or mathematics combined with biological sciences coursework.
Note: The Bureau of Labor Statistics groups biostatisticians under the broader occupational category "Mathematicians and Statisticians." Biostatisticians are not tracked as a separate occupation in BLS data, so salary and employment figures reflect this combined category.
If you're passionate about both mathematics and life sciences, biostatistics might be the career path that brings those interests together. This specialized field sits at the intersection of statistics and biology, where professionals use advanced mathematical methods to solve critical problems in healthcare, medical research, and public health. Whether you're exploring undergraduate majors or considering graduate school options, understanding what biostatisticians do and how to enter this field can help you make informed decisions about your educational journey.
What Does a Biostatistician Do?
Biostatisticians analyze data and statistics on living organisms collected during medical research studies to draw conclusions and make predictions. Think of them as the mathematical minds behind breakthroughs in medicine and public health. They transform complex biological data into actionable insights that shape everything from new drug approvals to disease prevention strategies.
Their work extends far beyond number crunching. Biostatisticians often collaborate with other scientists and medical professionals to design and execute research studies. During clinical trials, some monitor how studies are conducted to ensure the integrity of results won't be compromised. This quality control function is critical-flawed methodology can invalidate years of expensive research and delay potentially life-saving treatments.
Similar to environmental data analysts who interpret ecological datasets, biostatisticians must communicate their findings effectively to diverse audiences. Writing research proposals, composing scientific papers, and presenting results to both technical and non-technical stakeholders represent significant portions of the job. If you can explain complex statistical concepts to physicians, policymakers, or the general public, you'll stand out in this field.
Some biostatisticians teach at universities while conducting research, combining academic instruction with hands-on investigation. Performing fieldwork and collecting data firsthand also plays an essential role in certain positions, particularly in epidemiology and public health research.

But if you want to practice biostatistics professionally, a master's degree is the standard credential and opens most doors.
What's the difference between a biostatistician and a regular statistician?
The fundamental difference is domain specialization. Biostatisticians apply statistical methods specifically to biological, medical, and public health problems. They develop expertise in study designs common to medical research (randomized controlled trials, cohort studies, case-control studies), analytical methods for health data (survival analysis, epidemiological models, dose-response analysis), and regulatory requirements for pharmaceutical development. General statisticians work across diverse fields-finance, marketing, manufacturing, sports, government policy-and may use different methodological approaches suited to those domains. The statistical theory is similar, but the applications, context knowledge, and professional communities differ. Many biostatisticians begin with degrees in statistics and specialize through graduate training or early-career positions.
Can I become a biostatistician with a biology degree?
It's possible, but requires additional statistical training. A biology undergraduate degree alone won't qualify you for biostatistician positions because the role demands advanced statistical expertise. However, biology provides excellent domain knowledge that's valuable in biostatistics. Your path forward would typically involve: (1) taking additional undergraduate statistics and mathematics coursework to meet graduate program prerequisites, or (2) pursuing a master's degree in biostatistics or statistics, which is designed to bring students from diverse backgrounds up to professional competency. Many biostatistics programs specifically welcome biologists who demonstrate quantitative aptitude. Some universities offer "bridge" or "bootcamp" programs to prepare biology graduates for statistical graduate work. Your biology background becomes an asset once you develop the statistical skills-you'll understand the science deeply, which makes you a better collaborator and analyst.
What programming languages do biostatisticians use?
R and SAS dominate biostatistics work, with Python growing rapidly. R is widely used in academic biostatistics and increasingly in industry for its extensive statistical packages, data visualization capabilities (ggplot2), and reproducible research tools. SAS remains the standard in the pharmaceutical industry for regulatory submissions because the FDA accepts SAS outputs, and the software has extensive validation documentation. Python is gaining ground, particularly for machine learning applications, bioinformatics pipelines, and when biostatistics work intersects with data science. Most professional biostatisticians use multiple languages depending on project needs. Other tools you'll likely encounter include STATA (standard in epidemiology and public health), SQL (for database queries), and, occasionally, specialized software such as WinBUGS or Stan for Bayesian analysis. Learning R and Python during your education provides the strongest foundation, and you can pick up other languages as needed on the job.
Is biostatistics a stable career choice?
Yes, biostatistics offers excellent career stability and long-term prospects. The 8% projected growth through 2034 reflects sustained demand driven by pharmaceutical research, biotechnology innovation, public health initiatives, and healthcare quality improvement efforts. These needs aren't temporary trends-they're fundamental to medical progress and will continue regardless of economic cycles. Biostatistics skills are transferable across sectors (government, academia, industry, healthcare) and therapeutic areas, giving you flexibility if your interests or circumstances change. The advanced degree requirement also creates some barrier to entry, which helps maintain favorable supply-demand dynamics. While no career is completely recession-proof, biostatistics fared well during past economic downturns because pharmaceutical research and public health remain priorities even when discretionary spending contracts. The combination of strong growth prospects, competitive compensation, diverse employment options, and meaningful work makes biostatistics one of the more stable scientific careers available.
