For a growing share of young workers, financial security no longer means finding one good salary. It means making sure one employer, one client or one source of income cannot determine their entire financial life.
For decades, the basic formula for financial stability was straightforward: get a reliable job, earn a steady salary and gradually increase that salary over time.
A large share of Gen Z no longer appears convinced that one income source is enough.
A 2025 study from Fiverr, conducted with Censuswide, found that 67% of Gen Z respondents considered having multiple ways of earning money essential to achieving financial security. The Next Gen of Work research surveyed 12,003 Gen Z and Gen Alpha respondents across the United States, United Kingdom, France and Germany.
The same research found that 38% of Gen Z respondents were already freelancing or planned to freelance to create an additional revenue stream, while 46% said their biggest career fear was not earning enough to live comfortably.
Those findings make the 67% number more interesting than a simple enthusiasm for side hustles.
This is not necessarily a generation trying to avoid traditional employment. It is a generation increasingly uncomfortable depending entirely on it.
The distinction matters.
Multiple income streams can mean freelance clients, a small business, consulting, creator income, a second job, investment income or some combination of them. The common idea is not that every person needs several jobs.
It is that one paycheck increasingly feels like a single point of failure.
One salary is a form of concentration risk
The logic behind income diversification is familiar in investing.
Putting every dollar into one asset creates concentration risk. If that investment fails, there is nothing else supporting the portfolio.
Labor income has traditionally been treated differently.
Someone can spend years depending on one employer for nearly all of their earned income and still be considered financially stable because that income arrives predictably.
The weakness becomes obvious when the job disappears.
A worker can have valuable skills, a strong professional reputation and years of experience, but if nearly all of their income comes from one employer, a layoff can reduce earned income almost immediately.
Building a second income stream changes that exposure.
A worker earning 90% of their income from a salary and 10% from freelance projects is still highly dependent on the job. But they have something they did not have before: existing customers, evidence that someone else will pay for their skills and a route to earning outside the company.
The extra income itself may initially be modest.
The financial option it creates can be much larger.
That may help explain why younger workers increasingly talk about side hustles and freelancing as forms of security rather than simply extra spending money.
Financial pressure is an important part of the story
It would be easy to explain multiple income streams as a cultural preference for entrepreneurship.
The financial evidence suggests that interpretation is incomplete.
A 2025 global survey of 14,751 Gen Z respondents found that 48% did not feel financially secure, up sharply from 30% in the previous year’s research.
More than half, 52%, said they were living paycheck to paycheck, while 37% reported struggling to pay all of their living expenses each month. More than eight in ten said their day-to-day finances and long-term financial future contributed to feelings of anxiety or stress.
Those numbers come from a different survey covering 44 countries, so they should not be combined directly with the 67% headline statistic.
They do provide important context.
Wanting several income sources looks different when nearly half of the generation being studied already feels financially insecure.
For some young workers, a second source of income may be about entrepreneurship and independence.
For others, it may simply be the amount required to make the monthly budget work.
Those are very different versions of the same behavior.
A side hustle is not necessarily a second salary
One danger with the phrase “multiple income streams” is that it can make diversification sound larger than it really is.
Someone with a $70,000 salary and $150 a month of occasional freelance income technically has multiple ways of earning money.
That does not mean they have replaced dependence on their salary.
US side-hustle data makes the scale clearer.
A 2025 survey of 2,616 American adults found that 34% of Gen Z adults had a side hustle, a higher rate than Gen X or baby boomers.
But side-hustle earnings were highly uneven. Across all side hustlers, the reported average was $885 per month while the median was only $200. Among Gen Z side hustlers specifically, 45% earned more than $100 per month.
That distinction matters.
A small side income can still help with groceries, savings or debt. It can also become a starting point for a larger business.
But counting income sources tells us nothing about how economically important each one is.
Five tiny revenue streams do not automatically create more security than one strong salary.
The quality of the income matters as much as the number of sources.
Younger workers are planning for income portfolios even when they do not have one yet
The gap between current behavior and future ambition is especially revealing.
A separate 2025 survey of 1,500 Americans aged 18 to 25 found that 26% already had a side hustle.
Far more wanted one.
Thirty-seven percent said they wanted to start a side hustle, while 56% said they aimed to have two or three income streams within the next five years.
That is a much bigger number than the share currently running side businesses.
It suggests the important shift is happening first in expectations.
Younger workers are beginning their careers with a different mental model of what financial stability is supposed to look like.
Previous generations certainly held second jobs, ran businesses and earned income outside employment. Multiple-income careers are not new.
What may be changing is the assumption that diversification should be planned rather than treated as something unusual.
A salary can be the largest income stream without being expected to remain the only one.
Official employment data tells a less dramatic story
If two-thirds of Gen Z believe multiple income sources are important, it might seem reasonable to expect enormous numbers of young people to be working several jobs already.
Official labor statistics show why that conclusion would be premature.
In 2025, the US Bureau of Labor Statistics reported that 5.5% of employed people aged 20 to 24 were multiple jobholders, according to its annual data on workers holding more than one job.
That is nowhere close to 67%.
The difference is not a contradiction.
The two measures describe entirely different things.
The 67% figure captures an attitude about financial security across Gen Z respondents in four countries. The official US figure counts people who actually hold multiple jobs under labor-market definitions.
Someone can believe multiple incomes are important while still having only one job.
They can also earn money in ways that do not look like a traditional second job: occasional freelance projects, selling products, online content, investment income or a small business.
This is why attitudes about income diversification should not be presented as evidence that two-thirds of young people already have several jobs.
The interesting finding is that many think they should.
Freelancing fits naturally into an income-diversification strategy
Freelancing occupies an unusual position because it can be either a career or a supplement to one.
A worker does not need to become fully self-employed to start selling a professional skill.
A developer can take one project. A designer can work with one outside client. A marketer can advise a small company for several hours each month. A writer can complete occasional assignments alongside a full-time role.
That makes freelancing a relatively flexible way to test a second income stream.
There is no requirement for the experiment to become a full-time career.
Flexable’s guide to what freelancing is and how it works explains how independent work can range from occasional client projects to a person’s primary source of income.
That flexibility is important for income diversification.
Someone can begin small, learn whether clients will pay for a capability and increase the amount of independent work only if demand develops.
The professional upside is not limited to the money earned from the first few projects. Outside work can also reveal what a skill is worth without the pricing structure of an employer sitting between the worker and the market.
That information can influence everything from salary negotiations to future career choices.
A second income can provide resilience, but it can also add instability
There is an obvious problem with describing diversified income as automatically safer.
Some forms of second income are much less predictable than salaries.
Federal Reserve research shows the tradeoff clearly. In its 2025 report on household income and gig work, 41% of adults performing gig activities said their income varied from month to month, compared with 26% of adults who did not perform gig work.
Among self-employed adults, the figure was even higher at 59%.
Adding freelance or gig income can therefore diversify where money comes from while simultaneously making the amount received each month less predictable.
That is not necessarily a bad trade.
A worker might prefer one predictable salary plus one variable freelance income stream to relying entirely on the salary. But replacing a stable job with several highly uncertain sources of income is a different financial arrangement.
Diversification works best when the income sources do not all fail at the same time and when enough of the total income is dependable.
The same principle applies to freelancing itself.
A freelancer with five clients is generally less exposed to losing one buyer than a freelancer earning nearly everything from a single client. But independent work still carries risks around project gaps, late payments and uneven demand.
Flexable’s research on inconsistent work among freelancers shows why having several potential income sources does not automatically guarantee predictable monthly earnings.
Income diversity and income stability are related, but they are not the same thing.
Some side hustles are investments. Others are financial pressure in disguise.
The motivation behind additional work matters.
The same US side-hustle survey found that 35% of side hustlers used at least some of their additional earnings for regular living expenses, while 28% saved some of the money and 20% used it to pay down debt.
Perhaps more revealingly, 29% believed they would always need a side hustle to make ends meet.
That complicates the idea that multiple income streams are automatically empowering.
A software engineer who earns additional consulting income and invests it may be deliberately diversifying.
A worker who finishes a full-time shift and takes another job because the first paycheck does not cover rent is also earning from multiple sources.
Economically, those situations should not be treated as equivalent.
One creates optionality.
The other may reflect insufficient income from the primary job.
Any serious discussion of Gen Z and multiple income streams needs to leave room for both.
The popularity of side work can signal entrepreneurship, ambition and greater access to digital markets.
It can also signal that the economics of one job no longer feel sufficient.
The 67% finding becomes more meaningful when those explanations are allowed to coexist.
Digital work has made income diversification easier to attempt
One reason younger workers can imagine several income streams is that the cost of reaching customers has fallen.
A professional no longer necessarily needs an office, local customer base or traditional business infrastructure before selling expertise.
Freelance platforms can connect specialists with clients in other countries. Social platforms allow individuals to build audiences directly. E-commerce tools make it possible to sell products without operating a physical store. Digital payment systems make small international transactions easier than they once were.
AI is lowering some production barriers further.
One person can now handle parts of research, administration, content production, customer communication and basic technical work that might previously have required more time or additional people.
That does not mean every online income stream becomes profitable.
Lower barriers to starting also mean more competition.
What technology changes is the size of the initial experiment.
A worker can test whether people will pay for a skill before making a large financial commitment or leaving a job.
That makes income diversification accessible to far more people than traditional entrepreneurship.
Multiple income streams can also diversify skills
There is another form of security hidden inside the income story.
Earning money in more than one environment can diversify professional experience.
A full-time employee may spend years working with the same systems, customers and internal processes. A small freelance project can expose that worker to a different industry, type of client or commercial problem.
The second income stream can therefore create a second learning stream.
That becomes valuable when skills are changing quickly.
A professional who discovers demand for a new capability through client work can develop it before the same capability becomes important inside their main job.
This does not mean everyone should spend evenings working.
Time is limited, and additional paid work can create exhaustion rather than resilience if it simply extends the working week indefinitely.
The more sustainable version of income diversification is not necessarily doing more work.
It is creating more than one way for existing skills, assets or expertise to produce value.
That could eventually mean consulting, digital products, a small business, royalties or investments rather than continually adding more working hours.
The distinction becomes increasingly important as “multiple income streams” turns into a mainstream career aspiration.
Employers should not automatically read side income as disloyalty
The rise of income diversification creates an uncomfortable question for employers.
If an employee builds freelance income outside work, does that make them less committed?
Sometimes conflicts are real. Outside work can create problems involving confidential information, direct competition, working hours or performance.
Those situations require clear boundaries.
But the desire for another income stream does not automatically mean someone wants to leave.
It may mean the worker wants a larger financial buffer.
That distinction becomes particularly important when younger workers already feel less secure about money.
The original survey found that only 18% believed growing and staying at one company was the smartest career path.
That should not be interpreted as evidence that 82% refuse long-term employment.
It suggests that younger workers are less likely to assume loyalty to one organization is, by itself, the strongest career strategy.
Employers can respond to that reality in two ways.
They can treat every outside source of income as evidence of disengagement.
Or they can recognize that a generation entering an uncertain labor market may see professional independence as part of sensible financial planning.
Companies still have strong advantages to offer, including predictable pay, benefits, career development, colleagues and access to projects that would be difficult to pursue independently.
A worker can value those benefits and still want income outside the organization.
Financial diversification changes the meaning of career security
Traditional career security was largely institutional.
A stable company provided a stable job. A stable job provided stable income.
That relationship has never been perfect, but it shaped how generations of workers were told to build careers.
Income diversification introduces a different model.
Security comes partly from the worker’s ability to generate income beyond any single organization.
That could mean maintaining several clients, building a business alongside employment, developing an audience, owning income-producing assets or simply knowing that a professional skill can be sold independently when necessary.
This is closely connected to the wider expansion of independent work documented in Flexable’s report on the global rise of freelancing.
The important change is not that traditional jobs disappear.
It is that a good job may no longer feel like a complete financial strategy on its own.
For workers who adopt that view, employment becomes one part of an income portfolio rather than the entire portfolio.
The 67% figure needs one important methodological warning
The headline statistic comes from research conducted by Censuswide between April 9 and April 17, 2025.
The full survey contained 12,003 Gen Z and Gen Alpha respondents across the United States, United Kingdom, France and Germany.
More than 4,500 of those respondents were Gen Alpha participants aged 13 to 15. The public release does not provide the exact Gen Z subgroup size alongside the 67% headline figure.
That means the study should not be described as a survey of 12,003 Gen Z respondents.
It also covered four countries rather than the entire global Gen Z population.
The 67% figure measures respondents who said having multiple ways of earning money was essential to achieving financial security. It does not establish that 67% currently earn money from several sources, nor does it tell us how much income comes from each source.
It is an attitude measure.
Other evidence helps put that attitude into context. Large international research shows substantial financial insecurity among young adults, while US studies show meaningful interest in side hustles and multiple income streams. Official labor data, however, shows that traditional multiple jobholding remains far below the levels suggested by surveys of aspiration.
Those findings are not mutually exclusive.
They describe a generation whose financial model may be changing faster than its employment status.
What the number really tells us
The most interesting part of the 67% finding is not that young people want more money.
Every generation has wanted more money.
The change is in how many appear to think security should be constructed.
For much of modern working life, financial security meant making the primary income source stronger: find a better job, earn a promotion, increase the salary and stay employed.
The emerging model adds another possibility.
Keep the salary, but build something beside it. Develop a client base. Start a small business. Create an asset that earns independently. Learn a skill that can be sold outside the employer. Build a second route to income before the first one is interrupted.
That approach carries its own risks, particularly when additional income is volatile or requires simply working more hours.
But it changes the worker’s exposure to a single institution.
For Gen Z, that may be the deeper meaning behind the belief that one income is no longer enough.
The goal is not necessarily to have several jobs.
It is to have more than one way to stay financially standing.
