Job Growth Projections: How to Use BLS Data

When students weigh what to study, they fixate on the starting salary, which is the one number every article leads with. But a starting salary is a snapshot of a field today, and a new graduate will spend the next decade inside that field, where the question is not what it pays now but whether it will still be hiring. That is what job-growth projections answer. Reading them alongside earnings turns a static comparison into a forward-looking one, and it sometimes reverses the ranking that salary alone produces. This guide explains how to use the projections, as the forward-looking half of How to Choose a Major.

The projections carry an authority that most career advice does not. They are not a magazine's guess about which jobs are "trending," and they are not extrapolated from a single year of hiring headlines. They come from the federal government's labor economists, who model the whole economy a decade out and publish a number for every occupation on the same footing. That consistency is the point. Because the same method is applied to software developer and to registered nurse and to every field in between, you can compare two outlooks honestly, which you cannot do with the marketing copy a college puts on its program pages. The skill this guide teaches is small but decisive: read the projection next to the pay, understand what it is and is not telling you, and let it carry real weight in a decision that most people make on the salary number alone.

Why the Outlook Matters as Much as the Salary

The case for weighting projected growth is a timing argument. The decision is being made now, but its payoff plays out over the decade after graduation.

A field can pay well today and shrink over the next ten years, which means fewer openings, weaker bargaining power, and less security exactly when the new graduate is trying to establish a career. Another field can pay moderately today and grow steadily, opening more positions and more room to advance over that same decade. The salary snapshot favors the first; the trajectory favors the second. Because the graduate lives in the trajectory, not the snapshot, the outlook deserves weight equal to current pay, which is why it is one of the four factors in choosing a major.

What the Projection Measures

The forward-looking number comes from a single authoritative source.

Read the percentage against the all-occupation average, which is shown alongside it. Growth above that average signals an expanding field; growth near zero signals a stable but flat one; projected decline is a warning sign worth taking seriously. The average shifts over time, so the comparison is always relative to the current baseline rather than a fixed threshold. A projection is an estimate, not a guarantee, but it is the most rigorous forward read available and far better than guessing from headlines about which fields are "hot."

It helps to know roughly how the number is built, because that tells you what it can and cannot promise. The projection models where employment in an occupation will sit ten years out, driven by forces the analysts can reason about: an aging population that needs more healthcare, software that spreads into every industry, automation that thins some clerical roles, retirements that empty out others. The percentage you see is the net of all those pressures. What the model cannot see is the shock that nobody forecast: a recession, a pandemic, a technology that arrives faster than anyone expected. So treat the projection as the careful base case, not a promise. The honest way to use it is directional. A field projected to grow well above the average is very unlikely to be in freefall a decade from now, and a field projected to decline is unlikely to suddenly boom. The number narrows the range of plausible futures; it does not pin down a single one.

Combining Growth With Earnings

Neither number is sufficient alone. The fuller picture comes from reading growth and earnings together, because they describe different things and can point in different directions.

The pairing that students most often overlook is moderate-pay, strong-growth, because the salary headline buries it. Yet a field expanding faster than the economy offers more openings and more advancement over a career, which can outweigh a higher but stagnant starting wage. This is the kind of insight that only appears when growth sits next to earnings, which is how the career data on this site presents it.

Growth Versus Size

One more distinction prevents a common misread: a fast-growing field is not the same as a large one.

Growth is the rate of change; size is the absolute number of jobs. A small specialized field growing 30 percent may add fewer actual positions than a huge field growing 5 percent. High growth signals momentum and opportunity; large size signals many openings and stability. Both matter, and they are different. Read the projected growth percentage alongside the total employment figure on each career profile, because a high growth rate on a tiny base can promise more opportunity than it delivers, while steady growth on a large base quietly produces enormous numbers of jobs.

The Number Most People Miss: Openings

Growth and size together still leave out the figure that matters most to someone about to enter a field. A field can grow slowly and still hire constantly, because most of the hiring in any year is not new positions. It is replacement.

This is why a large, mature field with flat growth can still be one of the easiest places to find work: its sheer size means a steady stream of people retire or move on every year, and each of those exits is a vacancy a new graduate can fill. A small field growing fast may post a high percentage but generate only a handful of actual openings. When you read a career profile, hold three numbers in view at once: the growth rate (momentum), the total employment (size), and the projected openings where shown (the real flow of available work). The growth rate is the one the headlines quote, but the openings figure is the one that decides how hard your first job search will be. A field can score well on growth and still be brutally competitive to enter, and another can look sleepy on growth yet absorb new graduates every year without strain.

How to Use It

The practical workflow is to bring growth into the major decision rather than choosing on salary and checking growth as an afterthought.

For each candidate field, look at the projected 10-year growth and the total employment alongside the earnings range, all on the career profiles and via the Career Path Explorer, which lets you compare growth across careers and trace which majors lead into the fields with the strongest outlooks. Two careers worth contrasting are software developer and registered nurse, both with strong projected demand for different reasons. Weigh growth as a peer of earnings, not a footnote to it.

The order of operations is what separates a real read from a casual one. Do not pick a field on salary and then check growth to confirm the choice you already made. Bring growth in at the same moment you bring in pay, before you have an emotional stake in the answer. Build a short list of fields you would actually consider, pull each one's career profile, and lay the growth rate, the earnings range, and the size or openings figure side by side. The careers that survive that comparison are the ones that pay reasonably and are projected to keep hiring through the decade you will spend in them. That is a much shorter and more honest list than the one salary alone produces.

A Tale of Two Strong Fields

Two careers can both carry healthy projected demand and still reward you to enter them for completely different reasons. Contrast software developer and registered nurse, and the difference becomes a lesson in why the growth number always needs a second look.

Software developer is the field people picture when they hear "high growth." Its appeal is a combination of strong projected expansion and high pay, and the demand is driven by software spreading into industries that used to have nothing to do with it. But the same visibility that makes it attractive makes it competitive: everyone has heard the story, so the field draws a flood of candidates, and the high growth rate sits on top of an already large base. The outlook is real, but it does not hand you a job. It tells you the field will keep creating positions; it says nothing about how many people you will be competing against for each one.

Registered nursing tells the opposite story with the same conclusion. Its growth rate may look less dramatic on the page, but it is one of the largest occupations in the country, which means the annual flow of openings from retirements and turnover is enormous even before you count new positions. The demand is structural: an aging population needs more care, and that pressure does not switch off with the business cycle. A new nursing graduate enters a field that is hiring constantly, in nearly every geography, for reasons that are demographic rather than fashionable.

The lesson is not that one field beats the other. It is that "strong demand" means different things in each, and the growth percentage alone would have flattened that difference. One field is growing fast on a competitive, high-visibility base; the other is hiring relentlessly on a huge, structurally protected base. You only see which kind of strength you are looking at when you read the growth rate next to the size, the openings, and the earnings, which is exactly what the career profiles put in one place. Run any two fields you are weighing through the same comparison and the headline number stops being able to mislead you.

The Mistakes the Projections Invite

The growth figure is easy to read and easy to misread, and the same few errors recur. Each has a clean fix.

The first is chasing the highest growth percentage and ignoring the base it sits on. A tiny, specialized field can post an eye-catching growth rate while generating almost no actual openings, because a large percentage of a small number is still a small number. The fix is to never read growth without size: pull the total employment and, where shown, the projected openings on the career profile before you let a high percentage excite you.

The second is treating the projection as a guarantee instead of a base case. A ten-year forecast is the careful expected path, not a contract. A student who reads "fast growth" as "I am safe" has overweighted a single estimate. The fix is to use the projection directionally: a field well above the average is unlikely to collapse, a field in projected decline is a real warning, and the middle is genuinely uncertain, so let the size of the gap from the average tell you how much confidence the number deserves.

The third is looking at growth in isolation from pay and fit. A booming field that pays poorly, or one you would dread doing, is not a win. Growth is one of four factors in the major decision, alongside earnings, interest, and aptitude, and it cannot stand in for the other three. The fix is to read growth as a peer of earnings, the way How to Choose a Major frames all four, never as a standalone verdict.

The fourth is reading the growth of a major instead of a career. Majors do not have a growth projection; careers do. A student who says "this major is growing" has usually borrowed the outlook of one career the major can lead to and applied it to the whole field. The fix is to drop to the career level, the way Major vs Program vs Career lays out, and read the projection on the specific occupation the program actually feeds.

A Step-by-Step Read

Putting it together, here is the sequence for reading a field's outlook honestly, in the order that keeps you from fooling yourself.

Start with the growth rate, and immediately compare it to the all-occupation average shown beside it rather than judging it against a number in your head. Note whether the field is above the average, near it, or below it; that comparison, not the raw percentage, is the signal.

Next, read the size. Pull the total employment figure so you know whether the growth rate sits on a large base or a tiny one. A modest rate on a huge field can mean far more real opportunity than a spectacular rate on a small one.

Then look at the openings where the profile shows them, because that figure folds growth and replacement together into the closest thing to "jobs available per year." A field can disappoint on growth and still hire steadily here, or impress on growth and still be thin.

Now bring in the earnings range, not just the median, so you are weighing the trajectory against the pay at the same moment. Reading Earnings Data Honestly covers how to read that range; the point here is simply to look at it alongside growth, never after you have already decided.

Finally, set the field against your interest and aptitude. A strong outlook in a field you would resist doing is not a match. The projection earns its place as one of four factors, and the decision is sound only when all four point the same way. The Career Path Explorer lets you run several fields through this sequence at once and trace each strong outlook back to the programs and colleges that lead into it.

Where This Fits

Job-growth projections are the forward-looking factor in the choosing-what-to-study cluster, the natural companion to Reading Earnings Data Honestly, which handles the present-day pay side. Together they feed the data-validation steps of How to Choose a Major. The rule to carry forward: salary tells you what a field pays now, growth tells you whether it will still be hiring when you arrive, and the graduate lives in the second number as much as the first.
