Is it easier to switch careers, or to start over in an entry-level job?

Starting over means competing for the one percent of jobs that are actually entry-level. Switching means you already have about half of what the new job is asking for. Here is what 118,515 live postings say about both doors.

You want out of your job. Not in a dramatic way — you have simply worked out that the next ten years of doing this will look a lot like the last three, and that is not a thing you want. So you start looking, and almost immediately you hit the same fork everyone hits.

Door one: start over. Pick something new, accept that you are a beginner in it, and apply for the junior version of that job. It feels honest. You are not pretending to be something you are not.

Door two: move sideways.Find the job that is adjacent to what you already do — close enough that most of your skills come with you — and go in at your own level. This one feels like cheating. Like you are claiming credit for experience you have not really earned in that field.

Most people we hear from assume door one is the humble, sensible choice and door two is a shortcut that probably will not work. We count job postings for a living, so we went and looked at what is actually behind each door. The answer is not close.

Door one is mostly a wall

The problem with starting over is not that it is hard. It is that the jobs are not there. Across the 118,515 live postings in our corpus, the ones whose title actually says entry-level, junior, graduate or trainee come to 1,373. That is 1.16 percent — about one job in 86.

And it is not spread evenly. Design is the most open front door we measure at 2.76 percent, with Engineering at 1.63 and Finance at 1.61. Then it falls off a cliff. Education posts entry-level roles at 0.26 percent and Healthcare at 0.23 percent— roughly one in four hundred. If you were planning to retrain into care work or teaching by applying for the junior version, there is very nearly no junior version to apply for.

Sixteen occupations posted 300 jobs or more each, and not a single one of them was entry-level.

Those sixteen are worth naming because they are not obscure: actuary, construction manager, creative director, customer success manager, data architect, dental hygienist, dietitian, facilities managerand eight more. Thousands of open jobs between them. Zero front doors. These are not professions that are closed — people plainly do become facilities managers. They are professions you do not enter at the bottom, because the bottom is not advertised.

Even where the front door exists it is narrow. Software engineer is the single largest occupation in our corpus at 5,495 postings, and 90 of them are entry-level. That is the good case.

One more thing, offered as an anecdote rather than a statistic because the sample is too small to be anything else: among the handful of junior-titled ads that state a number, we found a posting titled “Junior Software Engineer” asking for three or more years of experience. We could not measure how common that is without overclaiming, so we are not going to. But you have seen it too.

Door two: you are further along than you think

Here is the part that surprises people. Moving sideways is not starting from nothing — and we can put a number on how much of it you already have.

For every occupation we track, we read what its postings actually ask for, then measure how much of a differentoccupation’s demands your current skill profile already covers. Not job titles. The stated requirements.

For the median occupation, the best available route already covers 46 percent of what that destination is asking for. Not 5 percent. Not a hopeful maybe. Just under half the stated requirements, on day one, before you learn anything new. And 62 percent of the occupations we track have at least one route sitting above 40 percent.

Door one: you compete for 1 percent of the market, starting at zero. Door two: you start at about half, and the whole market is open.

That is the asymmetry, and it is large enough that it does not need careful phrasing. Starting over asks you to fight for a sliver of the market from a standing start. Moving sideways lets you apply to the other 99 percent with half the work already done.

What the 46 percent does not mean

It is not a probability of being hired, and we will not pretend it is. It is the share of a destination’s typical stated requirements that your current profile already covers. Hiring involves a human reading your CV and deciding whether the story holds together. Nothing in a posting measures that.

The 1.16 percent has a caveat pointing the other way, and it matters: it is a floor, not a ceiling. We count a job as entry-level when its titlesays so, because titles are the one field no job board truncates. Plenty of genuinely junior roles never use the word. The true share of the market open to a true beginner is somewhat higher than 1.16 percent — it is just not much higher, and it is nowhere near the other door.

And some destinations are gated no matter how much your skills overlap. A licence is a licence. Our own numbers put architect to civil engineer at 53 percentreadiness — one of the strongest routes we measure — and it still requires a PE licence to take responsible charge of the work. The overlap is real and the gate does not move. Every route we publish that hits a credential says so on its face, with the time cost attached.

So what do you actually do

Stop looking for permission to skip the bottom rung and go find out which sideways moves are already open to you. The question is not “what do I want to be” — it is “what does the market already think I am qualified for.” Those are different questions and only one of them has an answer you can check.

Put your current role into the instrument and read the routes it returns. The percentage next to each one is the same measurement in this article: how much of that job’s stated requirements you already carry. Start with the ones above 40 percent. There are probably more of them than you expect.

Sources and methodEntry-level share is computed over the 118,515 mapped postings in the July 2026 corpus, counting a posting as entry-level when its titlematches entry-level, junior, jr, new grad, graduate scheme, trainee or apprentice and does not also carry a seniority marker. Title-only is deliberate: roughly four fifths of the corpus arrives from aggregators that truncate the description at 500 characters, so any body-text count would be biased toward the sources that ship full text. An earlier draft of this article measured entry-level from description text and produced a much more dramatic finding — that the median entry-level ad demands four years of experience. Spot-checking killed it: the ads were titled “Senior Software Engineer” and matched only because the word junior appeared somewhere in a long description. That number is not in this article because it did not survive its own check. Readiness figures come from the nightly adjacency scoring described in What career adjacency measures, over the 158 occupations that currently score at least one route (153 of those clear the publishing floor and appear on the site). All figures recompute with the nightly scrape.

Quick answers

Is it easier to change careers or start over in an entry-level job?

By the numbers in our corpus, changing careers sideways is easier. Entry-level roles are about 1.16% of live postings — one job in 86 — while the median occupation already covers 46% of the stated requirements of its best adjacent destination. Starting over means competing for a sliver of the market from zero; moving sideways means applying to the rest of it with roughly half the requirements already met.

How many jobs are actually entry-level?

About one in 86. Of 118,515 live postings we mapped in July 2026, 1,373 carried an entry-level, junior, graduate or trainee title. That is a floor rather than a ceiling, since some genuinely junior roles do not say so in the title.

Which fields still hire entry-level?

Design is the most open at 2.76% of its postings, followed by Engineering at 1.63% and Finance at 1.61%. Education (0.26%) and Healthcare (0.23%) are the tightest — roughly one posting in four hundred.

What does 46 percent readiness actually mean?

It is the share of a destination occupation’s typical stated requirements that your current occupation’s skill profile already covers, measured from live postings. It is not a probability of being hired and not a share of candidates. Licensed destinations stay gated regardless of overlap.

Do I need to take a pay cut to switch careers?

Not necessarily. Roughly a third of strong adjacent moves in our data point to a destination with a higher posted salary band than the origin. Every route on the instrument shows the destination’s posted band so the pay consequence is visible before you decide.
