People are skeptical of politicians. Skeptical of institutions. Skeptical of things we used to admire, like money managers and journalists.

And we're really skeptical of economic data. Tell a group of people that the unemployment rate is 5 percent and a significant portion will react like you referenced the tooth fairy. Fifty-seven percent of Americans thought the economy was in recession in 2014, according to an NBC/WSJ poll. Inflation was less than 2 percent in 2013, but 39 percent thought it was at least 5 percent, and 22 percent said it was double digits.

An important question is why people are so skeptical of economic data. Why is there a gulf between what's reported and what people believe?

One answer is that conspiracy theories never go out of style. But another force is becoming more important by the day, and helps explain everything from data skepticism to the rise of presidential candidates who wouldn't stand a chance a few years ago.

Personal experience

Most economic data references "the economy," in the aggregate or average. But no one lives in the economy. They live in their economy. And the difference between "the" and "their" is now enormous, and growing.

Take this stat by Jim Tankersley of The Washington Post:

"In the early 1990s recovery, 125 counties combined to generate half the total new business establishments in the country. In this recovery, just 20 counties have generated half the growth ...


"From 2010 through 2014, U.S. counties with 100,000 or fewer residents combined to lose more businesses than they created -- despite a growing national economy and a falling unemployment rate. In the recovery beginning in 1992, by comparison, those counties created a third of the nation's new businesses on net."

For perspective, 81.2 percent of counties have fewer than 100,000 residents, and are home to about a third of all Americans. During a period when "the" economy grew 19 percent, unemployment was cut in half, the stock market doubled and household net worth grew 39 percent, a third of Americans saw "their" economy do nothing of the sort.

So of course they're skeptical of the data. It's not that the data is manipulated or fraudulent. But the aggregate and average doesn't reflect what many people see in their own world.

Different perspectives

You can slice this dozens of ways.

• The unemployment rate for Asian women age 34-44 is 2.9 percent. For African-American men age 16-17, it's 45.1 percent.

• For those with a doctoral degree, unemployment is 1.7 percent. For those without a high school diploma, it's 8 percent.

• During the peak of the recession in 2009, the unemployment rate for those with a bachelor's degree never topped 5.3 percent. For those without a high school diploma, unemployment hasn't been below 5.3 percent in more than 30 years.

• Inflation-adjusted wages for men with advanced degrees have nearly doubled since the 1960s. They've declined for those without a high school diploma and barely budged for everyone else.

• The labor force participation rate for men has declined in 48 of the last 67 years. For women, it's increased in 51 of the last 67 years.

• The richest 1 percent of Americans have a life expectancy 14.6 years longer than the poorest 1 percent of Americans, and that gap has increased over time.

• The unemployment rate for men age 25 and up is 4.1 percent. For married men, it's 2.7 percent.

• We've always had an unequal economy. But the cultural and economic wedges today are larger than they were for much of the last 60 years. In a fascinating essay, Paul Graham wrote:

"(Two or three generations ago,) not only did everyone get the same thing, they got it at the same time. It's difficult to imagine now, but every night tens of millions of families would sit down together in front of their TV set watching the same show, at the same time, as their next-door neighbors. What happens now with the Super Bowl used to happen every night. We were literally in sync ...

"Everyone within this world was expected to seem more or less the same. And not just those in the corporate world, but also everyone who aspired to it — which in the middle of the 20th century meant most people who weren't already in it. For most of the 20th century, working-class people tried hard to look middle class. You can see it in old photos. Few adults aspired to look dangerous in 1950."

Fifty years ago, those with a college degree earned about 30 percent more than those without a degree; today they earn about 75 percent more. In his book "Coming Apart," Charles Murray gives an example of how different groups have skewed over the last half-century:

"As late as 1952, the mean SAT verbal score (now known as the Critical Reading score) of incoming Harvard freshmen was just 583, above the national mean but nothing to write home about. Then came the revolution. By 1960, the average SAT verbal score among incoming Harvard freshmen had jumped to 678. The average Harvard freshman in 1952 would have placed in the bottom 10 percent of the incoming class by 1960 ... (today) the typical classroom in an elite school has no one outside the top decile of cognitive talent, and many who are in the top hundredth or thousandth of the distribution."

Another powerful trend adds to this. The surge in U.S. manufacturing that came from a new world order after World War II benefited one group more than any other: white men without a college education. They were, in many ways, the most emboldened economic group for two generations, benefiting from relatively high pay and job security of labor-intensive manufacturing.

But those jobs — and that demographic — have been some of the hardest hit in relative terms over the last 40 years. Manufacturing employment peaked in 1979 at 19.5 million. Today it's 12.3 million.

Anytime an entire group sees their lot decline, the result will be skepticism of any reporting that "the" economy is growing, because their struggle appears widespread rather than anecdotal and individual. Derek Thompson of The Atlantic recently wrote:

"In February 2011, a national survey by The Washington Post, the Kaiser Family Foundation and Harvard University found that white men without a college degree had a uniquely dark outlook on America's future. They were the most likely to say the country's best days are over; the most likely to be pessimistic about the economy's future; and the most likely to say hard work no longer guarantees success."

They're skeptical not because of a character flaw or predisposition to conspiracy, but because the economy they see is so vastly different from the average or aggregate, which are skewed higher by the 20 counties that have boomed over the last six years.

Investors and economists like to argue over who's right. Keynesians vs. Austrians, bulls vs. bears. The more I dig into these debates, the more I see that people aren't actually debating the same topic; they're just trying to get the other side to see their own version of reality, and become frustrated and insulted when the other side can't or doesn't.

We all do this to some extent. It drives home that a vital skill of anyone trying to make sense of the economy is realizing that everyone has a point of view, and none of them is complete.
