The average American household lives in a housing unit with a median age of 39, built in 1976, according to the 2015 American housing survey. The AHS collected information about housing in the nation as a whole, in the 15 largest metro areas, and in 10 additional metros. Here are those 25 metros ranked by the age of their housing stock from youngest to oldest.

Modern Family: Why Children Are In Charge
Children rule, according to a National Bureau of Economic Research analysis of how parenting has changed over time. The outsized power of children in modern American families is a relatively recent phenomenon, and the NBER researchers theorize that children have become more powerful because competition within families has changed.
"The key intuition is that the rise in relative earnings of wives increased competition between spouses for the love and affection of their children," the researchers say, "while the decline in family size reduced competition between children for resources from their parents. The combined effect has empowered children."

Labor Force Participation of Older Men, 2016
The labor force participation rate of men aged 65 or older climbed to 24.0 percent in 2016, the highest rate since 1972. From an all-time low of 15.6 percent in 1993, the labor force participation rate of older men has climbed more than 8 percentage points in the past two decades. But it will be a while before the rate matches what it was in 1950, when 45.8 percent of men aged 65 or older were in the labor force.

Changing Age Distribution of Homeowners with Mortgages
Homeowners with mortgages are getting older, report researchers from the Federal Reserve Bank of New York. Analyzing CoreLogic and CRISM data, the researchers examined changes over the past decade in the age distribution of mortgage borrowers and the housing equity held by borrowers. The finding: older Americans (aged 61 or older) account for a growing share of mortgage borrowers as home buying slips among younger adults.

Why Aren't Millennials Moving?
The nation's geographic mobility rate has dropped to a record low. One factor behind the decline is the Millennial generation—younger adults, the people most likely to move. But younger adults aren't moving like they once did, reports Pew Research Center's Richard Fry. He examined trends in the geographical mobility rate of 25-to-34-year-olds over the past 50-plus years. The mobility rate of the age group was at all-time low of 20 percent in 2016.
Percent of 25-to-34-year-olds who moved in past year
2016: 20%
2000: 26%
1990: 27%
1981: 25%
1963: 26%
What accounts for the decline? One reason is the modest jobs recovery, suggests Fry. Job opportunities are not good enough to entice Millennials to move. Student debt also may be a factor, he says, preventing Millennials from buying homes. A survey of student loan borrowers by American Student Assistance confirms the impact of student debt on mobility. Among people with student loans, 43 percent say their debt has forced them to delay moving out of their parents' home, 46 percent say it has forced them to delay living on their own without roommates, and 57 percent said it has affected their ability to purchase a home.

17.5 Teaspoons of Added Sugars Per Day
The average American adult (aged 20 or older) eats 17.5 teaspoons of added sugars per day. Added sugars are those added to foods and beverages during production or preparation, including high fructose corn syrup used in soft drinks, ketchup, and other processed food. Do the math, and those 17.5 teaspoons of added sugars are 70 grams a day—far above the 37.5 grams for men and 25.0 grams for women recommended by the American Heart Association.

Can You Hear Me Now?
If you can, you still might have a hearing problem, according to the CDC. Among adults aged 20 to 69, a substantial 24 percent have noise-induced hearing loss. Even among those who think their hearing is good to excellent, nearly one in four has noise-induced hearing loss. These findings come from actual hearing tests administered to a nationally representative sample of adults aged 20 to 69 who participated in the National Health and Nutrition Examination Survey. Here are the key findings...

- 32 percent of men had signs of hearing loss versus 17 percent of women.
- Among adults aged 20 to 69, hearing loss was lowest among 20-to-29-year-olds (19 percent) and highest among 40-to-49-year-olds (29 percent).
- Among race and Hispanic origin groups, Mexican Americans were most likely to have hearing loss (32 percent). Blacks were least likely (21 percent).
- 23.5 percent of those who thought their hearing was good to excellent had hearing loss. Among those who reported having trouble with their hearing, an only slightly larger 28.3 percent had signs of hearing loss.
- 33 percent of those with work exposure to loud noise had signs of hearing loss.

Really Long Term Trends in Health Insurance Coverage
The number of Americans under age 65 who do not have health insurance is lower today than it was all the way back in 1972, reports the National Center for Health Statistics, despite a 46 percent increase in the population under age 65.
As recently as 2013, the percentage of the population under age 65 without health insurance was the same as in 1972—so, in four decades no progress had been made in expanding insurance coverage. Enter the Affordable Care Act, with marketplace plans up and running by January 2014, an effort that finally moved the needle. The percentage of Americans under age 65 who did not have health insurance fell from 16.7 percent in 2013 to the all-time low of 10.6 percent in 2015.

Median Household Income Falls in December 2016
Hmmm, this is bad news. Median household income fell in December 2016 to $57,827—a substantial 1 percent lower than the November 2016 median, after adjusting for inflation.
"The December decline in median annual household income wipes out most of the increase in income that had been evident since May 2016 and returns it to a level of income that is not significantly different than that at the beginning of the great recession," reports Sentier Research. The December 2016 median was 0.9 percent below the December 2015 median. It was 9.1 percent above the $53,019 median of August 2011, the low point in Sentier's household income series.
"Not only has median annual household income in 2016 not been able to maintain the momentum that it achieved during 2015," says Sentier's Gordon Green, but "it slipped by a formidable 1.0 percent in our latest reading for December. We continue to monitor the course of inflation, as this has a significant effect on the trend in real median annual household income." Sentier's median household income estimates are derived from the Census Bureau's monthly Current Population Survey.
Median household income in December 2016 was 1.8 percent higher than the median of June 2009, which marked the end of the Great Recession. It was not significantly different from the median of December 2007, the start of the Great Recession. The December 2016 median is 1.3 percent below the median of January 2000. The Household Income Index in December 2016 was 98.7 (January 2000 = 100.0).

American Health Care May Be "Uniquely Inefficient"
The U.S. health care system may be uniquely inefficient compared to other countries, according to a National Bureau of Economic Research study. NBER researchers compared the diffusion of drugs of high and low quality (defined by relative therapeutic benefit) in the U.S. versus their diffusion in Australia, Canada, Switzerland, and the United Kingdom.
Low quality drugs, they find, are adopted more quickly in the United States. This finding supports the theory that health care in the U.S. is inefficient relative to health care in other countries. "The U.S. health care system may be 'uniquely inefficient' in the sense of fueling the rapid adoption and diffusion of medical technologies with small or unknown benefits," the researchers conclude.

Ad Blocking May Threaten the Internet
"Use of Ad-Blocking Software Rises by 30% Worldwide," reports the New York Times. That could be a problem: "By using software to block digital advertising, critics say, users are breaking an unwritten pact with websites and digital publishers, many of which generate the bulk of their revenue from these ads."
A National Bureau of Economic Research study also sounds the alarm: "Ad blocking poses a substantial threat to the ad-supported web," say the authors of the study. According to their research, one-quarter of site visitors in 2016 used ad blockers and by doing so reduced the quality of web sites as determined by traffic ranks. After examining proprietary, site-specific data from 2013 to 2016, the researchers determine that each percentage-point increase in site visitors who use ad blockers worsens a site's traffic rank by 0.6 percent over a 35 month period. "We conclude that ad blocking poses a substantial threat to the ad-supported web."
