Rank all 38 major fields by what their graduates earn four years out and the distance between the ends is the story. The top field returns a median of $93,843. The bottom returns $36,949. That is a gap of 2.5 to 1, almost $57,000 a year, and it is not a close call hidden inside a long list. The two ends share almost nothing: the top is applied and technical work, engineering tech and computer science, and the bottom is arts, theology, and library science. The middle is crowded and the extremes are stark, and the choice between them moves a graduate's pay more than almost any other decision in the college process.
How Far Apart Are the Best and Worst Majors
Two and a half times apart. Engineering Tech graduates post a median of $93,843 four years after finishing, while Library Science graduates post $36,949, a difference of $56,894 every year. The gap is wide enough that the two fields do not compete for the same students, the same roles, or the same pay band.
The Two Ends of the Ranking
The table holds the four highest-paying and four lowest-paying fields, with the median earnings figure four years after graduation and the middle-half range that sits around it. The pattern at each end is consistent: technical fields cluster at the top, expressive and service fields at the bottom.
| Field | Median (4yr) | 25th pct | 75th pct |
|---|---|---|---|
| Engineering Tech | $93,843 | $77,403 | $111,740 |
| Computer Science | $92,374 | $64,179 | $128,180 |
| Construction | $90,924 | $71,807 | $105,984 |
| Engineering | $86,517 | $73,883 | $101,174 |
| Communications Tech | $44,889 | $26,703 | $61,587 |
| Theology | $44,533 | $29,498 | $62,259 |
| Visual and Performing Arts | $41,367 | $26,241 | $56,653 |
| Library Science | $36,949 | $23,200 | $51,608 |

What Explains the Gap
The gap is not random noise across fields that happen to pay differently. It tracks a single line: whether the work has a scarce, applied skill at its center. The top four fields all do. Engineering tech, computer science, construction management, and engineering feed roles with measurable output and clear labor demand, which sets a high wage floor even for graduates at the bottom of those fields. The bottom four feed smaller, more crowded sets of roles where supply outruns demand and the median stays low even for strong graduates.
The cleanest way to see how separate the two ends are is to look past the medians at the ranges around them. Engineering Tech's 25th-percentile earner makes $77,403. Library Science's 75th-percentile earner makes $51,608. The weak end of the top field beats the strong end of the bottom field by more than $25,000, which means the two distributions barely touch. A graduate is not choosing between two points on the same scale. They are choosing between two scales.
How We Measured This
Each major field is one of the 38 two-digit CIP families, the federal classification that groups all degree programs into broad fields. The earnings figure is the national median earnings four years after graduation for that field, drawn from the federal College Scorecard field-of-study data. The 25th and 75th percentile figures describe the middle-half range within each field. Fields with no reported earnings are excluded. The gap is the top field's median divided by the bottom field's median. Full method and source vintages are on the methodology and data sources pages.
What the Numbers Do Not Say
A field-level median hides as much as it reveals, and the caveats matter here. Each of these 38 fields contains many distinct programs, so a single field can hold both high-paying and low-paying paths that the median blends together. The earnings reflect who enrolls in each field as much as what the field teaches, and they capture only the first four years, before the long tails of some careers, such as the arts, have a chance to widen. The figures also say nothing about job satisfaction, security, or fit, all of which a student weighs alongside pay. A low median is a fact about a field, not a verdict on a person's choice to enter it.
What This Means for Students
The choice of field moves your earnings more than almost anything else you decide in the college process, so treat it as the first decision, not an afterthought once the school is picked. The gap between the top and bottom field, about $57,000 a year, dwarfs the roughly $5,000 that school selectivity moves earnings outside the most exclusive tier. That does not mean everyone should study engineering tech. It means a student drawn to a lower-paying field should enter it knowing the number, and a student near the line should weigh the gap seriously. Use the Career Path Explorer to see where each field actually leads before committing to it.
What This Means for Career-Changers
If you are returning to school to change your earnings trajectory, the field is the lever, and the steepest climb runs from the bottom of this list toward the applied and technical top. A move from a low-paying field into engineering tech or computer science is the difference between the two ends of a 2.5x gap, not a marginal bump. The full picture across every field sits in the ranking of all 38 majors by earnings, and once you have a target field, the ROI Calculator shows what the retraining costs against what it returns. The size of the gap is precisely what makes a deliberate switch worth the effort.
