It's interesting to observe the structural nature of these series. At no time (in the visible history of the chart) does the unemployment rate of a higher education level exceed the unemployment rate of a lower education level. Through recession, recovery and expansion, education looks to be a verifiably sound strategy for increasing your employment prospects.
Also worth noting (from the original link) is that the labor participation rate (employed + active job seekers as a fraction of the population) is higher as education levels increase. You're more likely to be working or looking for work the more education you have. Lower education levels have greater rates of people not working and not looking for work.
That assumes a causal relationship. The chart only shows correlation.
But here it's more than some vacuous claim to correlation.
Do you get unemployed as a BA first, or do you get your BA?
Econometrics is all about identifying causation in correlations in natural data (i.e. you can't run scientific experiments on people's lives, like telling random sample of people to go to college and others to not). Here, you just need intuition to realize that one thing consistently is a prerequisite to another, to realize that it's not just some statistical garbage.
There are three possible models to explain the correlation:
1. Something influences both one's propensity to get more education (E) and not get laid off (L).
2. One's education determines one's propensity to not get laid off
3. One's propensity to not get laid off influences one's education. This is nonsense.
In a Bayesian network, you can visualize 1. as features f0,...fi (say race, parents' income, etc) influencing both (E) and (L), with (E) also influencing (L) directly. 2. would be a set of features f0,...,fi influencing (E) but not (L), with (E) directly influencing (L).
So to conclude, "This chart only shows correlation" is a useless comment to make unless accompanied by an analysis of the possible probabilistic models that the evidence supports.
Correlation implies causality until proven otherwise? Do you work for the government?
> Statisticians know that when they are observing correlations they don't have statistical evidence for causation.
Scientifically inspired voodoo is still voodoo. Say those with higher education have lower employment, you still don't know why. These people could be wealthier than the rest and have better opportunities in life REGARDLESS of their "education" (as one example). The macro-economist would then cite this data point is proof for needing more spending in higher-education, when in reality, this may not be the case.
Where did I say that? I said that a comment like "this chart only shows correlation" is as useful as "The sky is blue." The sky is probably blue.

Please refer to the models that such data could support (my previous post). The joint influence of other variables like f0,...,fi is certainly discussed.

Please refrain from judging a profession unless it is one that you are familiar with. I mentioned econometrics, which is a specialized form of statistics that focuses primarily on extracting information from observational data.
You're trying to analyze the human motivation for action in hopes of altering future action, all inside a vacuum void of real-life tests. You claim this type of empirical knowledge is impossible to attain, "(i.e. you can't run scientific experiments on people's lives, like telling random sample of people to go to college and others to not).", but I would disagree.
Companies go to great length to mine data about their customers and their behaviors, with the opportunity to run a-b tests and isolate causal relationships. We should should recognize econometrics for what it is, and that is a theoretical science, and that anyone has the right to question the integrity of claimed causal relationships.
And criticizing people for pointing out that correlation does not imply causation is the newest, yet often useless, criticism in the world.
Read the context of my statement again. The comment to which I was replying called it "a verifiably sound strategy". Sounds a little strong when the only presented evidence does not control for factors like parents' income (or f0, ... fi as you call them).
Maybe some such evidence does control for those factors, but the evidence presented did not.
So to conclude, "This chart only shows correlation" is a useless comment to make unless accompanied by an analysis of the possible probabilistic models that the evidence supports.
I offered more than a simple criticism.
Thus it is still good advice to tell students to work hard and do well in school, rather than saying it's okay to be lazy and not pass exams because, well, "education is only correlated with employment prospects".
1. By entering the workforce as young as possible, total lifetimes earnings (and more importantly, savings) are maximized for a longer period of time.
2. If the individual has no aptitude (or desire) for higher education, then there is a very good chance they will neither get the credentials, nor the knowledge that comes with a high level education.
3. Even if they did manage to squeak by and, through sheer grit and determination and stubbornness, acquire the higher education - they might now slot themselves into a field of endeavor for which they are singularly not suited for - only to find 10 years after working some white collar position, that they really, really wished they had been in construction/electrician/blacksmith/what have you...
Frequently the path to maximizing total lifetime earnings, happiness, impact, and productivity is not through higher education. I think that there is a lot of observer bias on most of our part, because most of us have gone through at least some post-high school education and would to believe it generally offers value to those who do likewise.
I've got a least one friend who really should have never gotten his Computing Science degree. He is brilliant in ways that I'll never, ever, match - and should be building houses, not trying to work in IT - just not his gig.
On the flip side, i have a quite comfortable six figure income, and never completed university - I just have an aptitude for working in IT.
I really believe there is a correlation/causation problem with the "Higher educations leads to Higher Income" - the one exception being that a Yale/Stanford/Princeton/Harvard/MIT/Ivy League graduate probably raises the ceiling (and position opportunity) for candidates above what someone without those credentials would have. But now we're talking about the difference between making $150K/year as a mid level manager and $750K/year as a Sr. VP - not as relevant to the masses.
I did exactly that, out of high school into a warehouse job, then tech support, then software engineering, when I look at the cost of student loans, lost work, lost investment opportunities, I put the cost of my BA somewhere around $400,000.
There are definitely people who would be better off dropping out as early as possible and start working but that's a minority.
Even electricians and mechanics require tertiary education. (Otherwise, what does my brother training to be a mechanic mean when he says he's going to "class"?!)
Dropping education as early as possible might be a good idea if your aim is to work in a field where knowledge can be easily self taught. (Like IT or painting). Even then, a one year crash course I think would be quite helpful. I self-taught myself programming too, but I only learned about "unit-testing" in university. I guess you can argue I could learn that in my first job, but what if I want to, say, do a startup? ;)
>> I really believe there is a correlation/causation problem with the "Higher educations leads to Higher Income"
We're talking about higher education leads to higher chance of being employed.
I didn't take "looks like" as a mere hedge on the claim, because the poster clearly said "verifiably sound".
There are PLENTY of reasons why it might not be worth it to spend as many years in education as society allows.
As a high school drop-out in the computer industry, the industry does not seem the least bit "flacid" to me.
Of course, I also had comparatively wealthy parents and an otherwise privileged upbringing, very similar to that of many individuals that comprise the lowest unemployment bracket.
Seeing this chart broken out by, say, parental income and assets would be interesting.
I'm not trying to make the absurd point that education is useless/bad, just that this is heavily conflated with all sorts of age/race/class confounding factors. The factors that might lead to outcomes like "less that a high school diploma" or "_some_ college" include things that won't be great for employment either - chaotic home life, illness or disability, requirement to care for illness/disability, being a participant or a victim in crime, drugs or alcohol abuse - or having parents that are affected by these factors.
Not wanting to be too snarky here, but a lot of posts (not yours, specifically) on inequality and social problems here on HN take on a unpleasant tone of undergraduate geek self-congratulation - "how _smart_ I am to be getting a degree with teh computers, if only all those poor people were as hard-working and clever as I am".
"because they're browner than me they deserve to be poorer than me"
Now, I now that isn't what the OP probably intended, but (like sexism) the racism bias still runs deep in that land and is subtle and insidious.

In short, yes, the trend continues.

seems not to have had much discussion, perhaps because the submitter retitled the story, but the submitted story has a lot of good discussion on the value (or not) of attending college, and is worth thinking about in connection with the statistics submitted here.
I saw a posting for my local city's parks department for a person who basically mows grass. Education requirements? High school diploma, associates degree preferred.
The correlation/causation issue is that we assume that no jobs for folks out of high school equates to no "low skill" jobs.
Someone who has no interest in working hard to attain good grades in high school and therefore does not go to college is, generally speaking, someone who has no interest in working hard to get a good job. However, if you took one of those employed college grads and stripped them of their degree, I think we would find their success in business would remain unchanged. It is the person, not the degree, that leads to employment.
Ultimately, we simply do not have enough information to reach any conclusions from the data.
We're in discussions regarding the purchase our small company, where I serve as (a technical) CEO. I'd be joining the purchasing company as CTO; nobody yet has asked me about having a degree in anything.
For most jobs, what educational requirements really express is the minimum level of skill in written and verbal communication, analytical abilities, and a sufficient level of proficiency in the trade in question.
When everyone in you field went to college, nobody even bothers to question whether you did, too.
But the situation is much worse than the statistics show. They dont count people who are too discouraged to look for work, those who would take a job if one were realistically available. Also not counted are those who are working fewer hours than they want. Typically the unemployment statistics underestimate by a third. I surmise, but havent dug into it, that the under-counting is correlated with education: unemployment is probably double the BLS number for the dropouts. And for those under 25, it is over 50%.

NY Times: The Jobless Rate for People Like You (2009)

Plots unemployment by race, education level, age and sex.
Unemployment in government statistics is an economic-political term basically defined as "people who are able to work, who are actively looking for work and have been for the last 4 weeks"
Its important that they are "actively" searching for work. This is generally (in most countries, including Canada and the United States) defined the same as it is in the relevant welfare codes: looking at job ads, submitting resumes, making physical effort to find a new job (albeit, the extent to which that effort is made is hard to measure)
http://www.bls.gov/news.release/empsit.t01.htm
there are 239,146 people aged 16 and over in the US who are civilians and not in institutions (like prisons or hospitals), of which only 139,674 are employed.
That leaves 99472 unemployed. Which is about a 42% unemployment rate.
In 2006, ~30 million people were enrolled in the final two years of HS, college, or graduate school: http://www.census.gov/prod/2008pubs/p20-559.pdf
Adjusted for demographic trends, that's probably higher now.
In 2009, about 12.9% of the population was over 65: http://quickfacts.census.gov/qfd/states/00000.html
Together that's roughly 70 million people who are mostly being counted in your "unemployed" figure that shouldn't be included.
That's not even including women who don't work. There is still a delta of ~13% b/w male and female labor force participation rates. They're 122 million women age 16 and over in the US. That's probably another ~10m who shouldn't be included in your unemployed figure.
The above estimates double-count: those enrolled in school who work, elderly who work, etc, but is much more realistic than your figure.
For instance, you say, "women who don't work ... shouldn't be included in your unemployed figure." Why not?
Another issue is that those counted as employed include a large number of underemployed, i.e people forced to work part time because they can't find more work.

and, specifically,
http://www.bls.gov/cps/cps_htgm.htm
The United States federal definition of unemployment and labor force participation are
"Who is counted as unemployed?
"Persons are classified as unemployed if they do not have a job, have actively looked for work in the prior 4 weeks, and are currently available for work.
"Workers expecting to be recalled from layoff are counted as unemployed, whether or not they have engaged in a specific jobseeking activity. In all other cases, the individual must have been engaged in at least one active job search activity in the 4 weeks preceding the interview and be available for work (except for temporary illness).
"Who is not in the labor force?
"Persons not in the labor force are those who are not classified as employed or unemployed during the survey reference week.
"Labor force measures are based on the civilian noninstitutional population 16 years old and over. (Excluded are persons under 16 years of age, all persons confined to institutions such as nursing homes and prisons, and persons on active duty in the Armed Forces.) The labor force is made up of the employed and the unemployed. The remainder--those who have no job and are not looking for one--are counted as 'not in the labor force.' Many who are not in the labor force are going to school or are retired. Family responsibilities keep others out of the labor force."

I think because the current experiment of not showing comment karma scores (other than your own comment karma scores) is done with minimal changes to the existing code base. See

> Correlation is not causation, etc.
This certainly is a true and tested adage, but I've got a feeling that the correlation-backlash has gone too far in the other direction. Don't just repeat it without getting it. If substantiated through proposal of a suitable mechanism, correlation is solid corroboration of a causality-claim.More precisely, correlation most definitely never implies absence of causation.
