What the IPEDS & College Scorecard Data Shows for Ecology, Evolution, Systematics, and Population Biology
Ecology, Evolution, Systematics, and Population Biology is tracked across 122 U.S. postsecondary institutions in the College Scorecard field-of-study file, which links CIP code classifications from IPEDS to Treasury earnings records. This profile covers the doctoral credential level specifically, because the Department of Education reports program-level outcomes separately for associate, bachelor’s, master’s, and doctoral awards. The CIP (Classification of Instructional Programs) taxonomy lets analysts roll up specialties into broader families, which is why earnings medians across schools can be compared on a common basis.
Across all reporting institutions, the mean of school-level medians is $104,630, calculated from 8 schools with published earnings data. The earnings distribution stretches from $70,373 at the low end to $185,905 at the top, with a 25th-75th percentile band between $85,764 and $117,823 around a median of $96,987. The top-reporting institution in this program is Harvard University at $185,905. These numbers reflect Treasury-derived wages, deferred compensation, and positive self-employment earnings four years after completion for federally aided completers who were working and not enrolled.
Variation across schools matters more than a single national figure. Completer counts and earnings cohort counts are distinct source fields, so the displayed completer count should not be assumed to be the earnings denominator. PlainCollege's debt-to-earnings ratio divides median federal debt by annual median earnings as a descriptive comparison; it is not the Department's formal gainful-employment test. Use the school-by-school table to compare reported outcomes while accounting for cohort size, suppression, program mix, and location.
Harvard University accounts for 17.9% of all Ecology, Evolution, Systematics, and Population Biology doctoral credential graduates
That concentration — well above the 5% national median for largest-entity share means Ecology, Evolution, Systematics, and Population Biology-wide averages can mask meaningful variation outside the largest entity, though the remaining entities individually still carry a share worth reading on their own. That school produced 52 graduates in the most recent cohort, anchoring a meaningful slice of national supply for this field. Even a notable-but-not-dominant share like this is enough to skew a simple Ecology, Evolution, Systematics, and Population Biology-wide average away from what a typical smaller entity looks like.
Ecology, Evolution, Systematics, and Population Biology doctoral credential median earnings varies 2.6× across entities
Ecology, Evolution, Systematics, and Population Biology doctoral credential median earnings ranges from $70,373 (lowest) to $185,905 (highest), a spread of $115,532. That spread reflects typical sectoral variation between selective research institutions and broader access institutions. Earnings are measured four years after completion using Treasury-derived records for federally aided completers who were working and not enrolled. They are descriptive early-career outcomes, not forecasts of longer-term earnings.
Ecology, Evolution, Systematics, and Population Biology debt-to-earnings ratio is 0.38 — low (typically associated with graduates earn substantially more than they borrowed, which is the College Scorecard standard signal for affordability, a ratio under 0.5 means a year of post-completion earnings would clear half the federal-loan principal)
debt-to-earnings ratio is the simplest comparative metric but it does not capture the full picture: this ratio uses federal loan principal, not all education debt, private loans, parent PLUS loans not in the borrower’s name, and institutional debt are excluded Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
Earnings trajectory. For the 7 schools reporting both horizons, median earnings are
70% higher four years after completion than one year
after. That is the same graduates measured twice, not two different groups, so it
describes how pay develops early in the career rather than a difference between schools.
A school missing from this count reports only one horizon.
Awards and earnings come from different reference periods, so they are not a count and an
average of the same people. Awards is the number of credentials the school reported for the
latest IPEDS year; median earnings is measured four years after completion, for a separate
pooled cohort of earlier graduates. A school can therefore report zero awards in the latest
year and still have earnings on record. The earnings figure is not the awards figure’s
average, and the awards count is not the earnings sample size. Schools are ranked on the
four-year earnings figure only, so every row is compared on the same basis.

Nationwide peers by school count & four-year earnings
Cross-field programs at the same credential level nearest Ecology, Evolution, Systematics, and Population Biology on school-count breadth
(122 schools) and mean four-year median earnings ($104,630).
Peers exclude the same two-digit CIP family so neighborhoods are not CIP-containment siblings.
School-count peers include Education, General, Music, Pharmacy, Pharmaceutical Sciences, and Administration. Earnings peers include Educational Administration and Supervision, Clinical, Counseling and Applied Psychology, Psychology, General.
Neighborhoods are forced disjoint so each axis surfaces a different set of programs.

How much do Ecology, Evolution, Systematics, and Population Biology graduates earn? ▼
Ecology, Evolution, Systematics, and Population Biology graduates earn $104,630 on average four years after completion, across the 8 of 122 schools that report earnings for this program. Earnings range from $70,373 to $185,905 depending on the institution.
Which school's Ecology, Evolution, Systematics, and Population Biology graduates earn the most? ▼
Harvard University has the highest reported median earnings for Ecology, Evolution, Systematics, and Population Biology graduates at $185,905, measured four years after completion in College Scorecard data. This reflects what graduates went on to earn, which depends heavily on who the school admits and which employers recruit there. It is not a figure the school pays.
What credential do you get in Ecology, Evolution, Systematics, and Population Biology? ▼
Ecology, Evolution, Systematics, and Population Biology programs typically award a Doctoral credential. Earnings vary by school and credential level.

Earnings data comes from the U.S. Department of Education College Scorecard Field of Study file retrieved in March 2026. The program metric displayed here represents federally aided completers who were working and not enrolled four years after credential completion, using Treasury-derived records published through the Scorecard. Completer counts and debt figures come from the same field-of-study snapshot; the Department refreshes components on schedules documented in its changelog, not one fixed annual date.
