One possible positive of higher gas prices: less deaths

For the average American, driving or riding in a car is perhaps their most risky daily activity. So if gas prices go up (with the Chicago region leading the nation) and driving goes down, then less Americans may be killed on the road. This is according to a recent study of Mississippi data:

Traffic accidents seem to go down — even ones because of drunken driving — as gas prices go up.

“The results suggest that prices have both short-term and intermediate-term effects on reducing traffic crashes,” Guangqing Chi, assistant professor of sociology at Mississippi State University and demographer at Mississippi State’s Social Science Research Center, and colleagues wrote.

In their research, published in two recent studies in the Journal of Safety Research and Accident Analysis & Prevention, the researchers looked at car accidents in Mississippi between 2004 and 2008, and tracked gas prices during that period. The prices seemed to affect younger drivers the most in the short-term (over one month) and older drivers and men over a one-year period.

In addition, the investigators found a strong link between higher costs at the pump and a drop in frequency of drunken-driving crashes, they noted in a university news release.

This is data from one state so it would be interesting to see if such relationships hold in additional states.

But these arguments about safety in light of generally negative public opinion (regarding gas prices here) can provoke some contentious conversations. Some members of the public are bound to ask whether the government is most interested in safety or in revenue? The same issue has been raised with red-light cameras and I also ran into similar arguments about particular developments when doing research into the growth of nearby suburbs.

For the average American, would they rather have a higher risk while driving (which they probably don’t think about anyway) or lower gas prices? This seem easy to answer and I wonder if the safety argument will gain any traction at all.

Nielsen reports a drop in American household TV ownership in America

A new report from Nielsen suggests fewer American households have televisions:

The Nielsen Company, which takes TV set ownership into account when it produces ratings, will tell television networks and advertisers on Tuesday that 96.7 percent of American households now own sets, down from 98.9 percent previously.

There are two reasons for the decline, according to Nielsen. One is poverty: some low-income households no longer own TV sets, most likely because they cannot afford new digital sets and antennas.

The other is technological wizardry: young people who have grown up with laptops in their hands instead of remote controls are opting not to buy TV sets when they graduate from college or enter the work force, at least not at first. Instead, they are subsisting on a diet of television shows and movies from the Internet.

Nielsen suggests that affordability is really behind this drop in TV set ownership. But of consumer goods that are truly American, isn’t having a television at the top of the list? More than owning a car or a home (granted, these are more expensive) or a radio or a microwave (a lower ownership rate than TVs according to this), the television is a critical part of average American life. And with all of the purchases in recent years of nicer TV sets (LCD, plasma, 3D, LED, digital tuners), there are plenty of older TVs laying out or available for a low price at garage sales, consignment shops, and on Craigslist.

It makes sense that Nielsen is very interested in these figures. Nielsen’s methodology may not seem important to some people but these ratings are incredibly important for the TV industry. These ratings help set advertising rates which drive the industry and dictate which shows survive on the air and which do not. If ratings go up (whether that is because the show is more popular or because Nielsen can show that more people watch it), then networks can ask for more money.

If household TV ownership rates keep dropping, how might this affect the TV industry and TV networks?

A sociologist argues younger generation need self-help messages

After researching self-help books, a sociologist argues that Millennials need the messages of classic self-help books in order to navigate modern relationships:

When assistant professor of sociology Christine Whelan, 33, set out to study the rise of the self-help industry ten years ago, she was skeptical. But after reading hundreds of books, writing her doctoral dissertation on the subject at Oxford, and then teaching more than 400 students, Whelan, now at the University of Pittsburgh, realized that several self-help classics had a lot to teach a generation of people who are expert at texting and other sorts of online communication, but ill-schooled in the art of face-to-face communication and self-presentation…

Whelan got the idea to start teaching self-help classes, which she framed as the sociology of self-improvement. She was surprised to discover how eager her students were to absorb the lessons taught in books like Dale Carnegie’s How To Win Friends and Influence People, first released in 1937, M. Scott Peck’s The Road Less Traveled from 1978 and Stephen Covey’s 1989 The Seven Habits of Highly Effective People. “They were raised in a therapeutic culture,” she notes. “That separates this generation of job-seekers from others.”…

After putting hundreds of students through her course, Whelan says she came up with some lessons that combine 20th century common sense with 21st century lives. She combined them into a new self-help book aimed at Millennials, Generation WTF. I asked her to boil down the points most salient to job seekers, and illustrate them with some anecdotes. Notes Whelan, “nothing in this is rocket science. But it’s new to them and it works.”

The six steps that are then laid out seem fairly obvious but perhaps Whelan is right about the need to teach this material. There does seem to be a lot of articles floating around these days that talk about the crazy things that people interviewing for jobs do.

So what exactly goes on in a “sociology of self-improvement” class? While it sounds odd when you first hear about it, it could end up being an interesting course about human interaction. I wonder if there is any critique of the self-help movement.

The relationship between gasoline prices and taxes and sprawl

The Infrastructurist discusses  a recent study that suggests that an increase in gas prices leads to a reduction in sprawl. Here is a summary of the study:

Georges Tanguay and Ian Gingras analyzed data from the 12 largest metropolitan region in Canada for the period of 1986 to 2006 and found that higher gas prices “contributed significantly” to less sprawl:

On average, a 1% increase in gas prices has caused: i) a .32% increase in the population living in the inner city and ii) a 1.28% decrease in low-density housing units…

Tanguay and Gingras addressed this shortcoming by expanding their observations over a 20-year window. The researchers found the aforementioned link between higher gas prices and reductions in sprawl. They also report that a 1 percent increase in gas taxes led to a .2 percent reduction in commuting distance (though the effect is small, amounting to just 14 fewer meters of travel, on average).

The researchers did notice a potential mitigating factor: income. Every 1 percent rise in median income led to a .23 percent decrease in city center living. That means any reduction in sprawl that occurred as a result of rising gas prices could be offset by rising income.

So if gas prices went up more than $2 on average in the US between late 2008 and today (roughly a 140% increase), then we would expect the inner city population to grow by 44.8% (.32% increase in population*140) over the same time period? Perhaps this is extrapolating beyond the scope of this data but this would be quite a population shift. Even a smaller increase in gas prices, say 10%, would lead to a predicted increase of 3.2% in inner city population, still a sizable increase.

It would be helpful to take the same kind of analysis and apply it to American metropolitan areas. Does the same relationship hold? I suspect it might not as some big central cities have not really gained much population in the last decade (see the case of Chicago or New York City). Could some of this observation come from how the Canadian government measures city centers or from a higher proportion of Canadians living in the “city center” (the study suggests the proportion of the population living in city centers is “the average for Canadian CMAs is 55%” – the American population is at least 50% suburban)? Does Canadian culture have less emphasis on sprawl (and single-family homes with yards, driving, etc.) compared to American culture?

This is an interesting finding but I would be interested in seeing more research on this. A 2004 American study cited in the discussion reached this conclusion: “The results show that every penny increase in the state gasoline
tax in the late 1980s is associated with nearly a five square-mile reduction in the size of an average urbanized area.” Additionally, I would be curious to hear more about why this study used the “average-sized” urban area in a state as the dependent variable:

The dependent variable, the average-sized urban area in the state, ranges from a high of337.8 square miles (Arizona, given the large size of the Phoenix metropolitan area) to a low of29.34 square miles (West Virginia). The mean of the dependent variable is just over 120 square miles, which, for point of reference, is slightly more than double the size of the urban area contained in the Burlington, Vermont metropolitan area, or just under the size of the urbanized land area in the Anchorage, Alaska metropolitan area.

I see that the gas tax measure of interest is at the state level but using state level data for cities seems strange as urbanized areas can vary quite a bit (think of the comparison between Chicago, IL and Springfield, IL – both urban areas but quite different in scale and urbanization). Additionally, a measure like the percentage of state residents who use public transportation to get to work would seem to be related to the size of urban areas. Why not simply use each urbanized area as a case?

The psychology and sociology of being a soldier

This piece discusses the psychological states of soldiers. A quick summary: studies after World War II found that most soldiers were not shooting to kill, training in subsequent decades effectively trained soldiers to kill, a recent study suggests that post-traumatic stress disorder (PTSD) rapidly increased among American soldiers, starting in Vietnam, but didn’t increase among British soldiers, and a new book argues that American soldiers have more PTSD simply because they were expected to.

Sounds like an interesting subject area: how are individual soldiers affected by training techniques that prepare them to kill? What seems most interesting here is the disparity in PTSD between British and American soldiers. It reminds me of a book I read years ago that suggests that ADD and ADHD diagnosis rates differed greatly between the United States and Britain. This finding was partly based on studies that had shown that the same kids who visited both American and British doctors were evaluated differently, suggesting that cultural differences might be behind the medical expertise. Has anyone done a similar study with the same British and American soldiers being evaluated by both British and American doctors?

While the interest here is in a psychological topic, this sounds more like a sociological question relating to cultural values and expectations.

Popular music has become more narcissistic in recent decades

Several psychologists argue that pop music has become increasingly narcissistic over recent decades:

Now, after a computer analysis of three decades of hit songs, Dr. DeWall and other psychologists report finding what they were looking for: a statistically significant trend toward narcissism and hostility in popular music. As they hypothesized, the words “I” and “me” appear more frequently along with anger-related words, while there’s been a corresponding decline in “we” and “us” and the expression of positive emotions…

His study covered song lyrics from 1980 to 2007 and controlled for genre to prevent the results from being skewed by the growing popularity of, say, rap and hip-hop…

Today’s songs, according to the researchers’ linguistic analysis, are more likely be about one very special person: the singer. “I’m bringing sexy back,” Justin Timberlake proclaimed in 2006. The year before, Beyoncé exulted in how hot she looked while dancing — “It’s blazin’, you watch me in amazement.” And Fergie, who boasted about her “humps” while singing with the Black Eyed Peas, subsequently released a solo album in which she told her lover that she needed quality time alone: “It’s personal, myself and I.”

The majority of this article is about how narcissism is measured and how it shows up in younger generations.

But I would prefer to see more thinking about why music has changed in this way. A broad question could be asked: does or should pop music reflect culture or change culture? I would suggest that it does both but it would be interesting to see data on this: is music more narcissistic because people are more narcissistic or are people more narcissistic because music is more narcissistic? Answering this broad question also requires figuring out what music really means to people. For younger people, listening to music is an important activity and is an integral part of adolescence and emerging adulthood.

This recent study also tries to get at this question and can’t say much about the direction of causality:

With each level increase in music use, teens had an 80% higher risk of depression, the study found.

The study didn’t measure total listening times, but based on previous data, the study authors estimated that teens in the highest-use group were likely listening to music for at least four or five hours a day…

“At this point, it is not clear whether depressed people begin to listen to more music to escape, or whether listening to large amounts of music can lead to depression, or both,” said Primack in a statement.

By contrast, researchers found that reading books had the opposite association: with each level increase in time spent reading, teens’ risk of depression dropped 50%. “This is worth emphasizing because overall in the U.S., reading books is decreasing, while nearly all other forms of media use are increasing,” Primack said.

This contrast to reading is interesting. Does this suggest that listening to music is more self-indulgent while reading is not?

Overall, it sounds like we need more research to sort out this issue. Music is more narcissistic, the culture may be more narcissistic, this has an effect on people, but it is a bit unclear which direction the causal arrows go. If only we could design some sort of controlled experiment that could isolate the effect of more narcissistic music…

Another article on declining homeownership rates

Bloomberg Businessweek highlights how American’s view of home ownership has changed in the last few years:

The most affordable real estate in a generation is failing to lure buyers as Americans like Pauli sour on the idea of home ownership. At the end of 2010, the fourth year of the housing collapse, the share of people who said a home was a safe investment dropped to 64 percent from 70 percent in the first quarter. The December figure was the lowest in a survey that goes back to 2003, when it was 83 percent.

“The magnitude of the housing crash caused permanent changes in the way some people view home ownership,” said Michael Lea, a finance professor at San Diego State University. “Even as the economy improves, there are some who will never buy a home because their confidence in real estate is gone.”…

“If we’ve learned anything from this mess, it’s that housing is not a risk-free investment,” said Michelle Meyer, a senior economist at Bank of America Merrill Lynch Global Research in New York. “Everyone knows someone underwater in their mortgage or struggling to sell a home.”…

The U.S. home ownership rate dropped to 66.5 percent in the fourth quarter, the lowest in more than a decade, according to the Census Department. The rate probably will retreat another percentage point by 2013, according to Meyer, of Bank of America Merrill Lynch, and Lea, the finance professor. That would put it back to a 1997 level.

“People will still aspire to own their own homes,” Lea said. “They’ll just be a lot more practical about it.”

This article tends to focus on the money side of things (housing as less of an investment, tighter credit, lots of people with underwater mortgages, a future with a reduced or no involvement from Fannie Mae and Freddie Mac, etc.) but I think the key (or exciting) information is in the last two paragraphs I cited above:

1. The homeownership rate has dipped but not a whole lot. Even in the housing boom of roughly the mid 1990s to the mid 2000s, the US homeownership rate increased from 63.6% in early 1993 to 69.2% in late 2004. So over an eleven year stretch of relative prosperity and increasing home values, homeownership rose about 6.5 percentage points. From this peak in late 2004 (69.2%), the homeownership rate had dropped to 66.5% for the fourth quarter in 2010. In a six year stretch, the rate had dropped 2.7%. If you look at the historical data since 1965 (all of these figures are from an Excel table on the Census website – Table 14 on this page), before the 1990s, the homeownership rate moved fairly slowly either up or down. Perhaps what is not so unusual about homeownership is not that it has fallen in recent years but rather that it rose so much between 1993 to 2004.

2. Additionally, this is all tied to American aspirations: do they still aspire to own their own home? While this article (and many others) highlight how this might now be more difficult, this key part of the American Dream still seems to be intact. Even if future neighborhoods or suburbs look different (like this article suggests they might), the interest in owning one’s property still appears to be high. While there is no guarantee that more and more Americans will be able to own their own homes (how high might the American homeownership rate realistically go anyway?), it will likely take more than this what has happened in this particular economic crisis to cast a new vision of American fulfillment that doesn’t include a single-family home or space.

The evolving American Dream: more dense but still private

I’ve written about several aspects of the American Dream including unhappiness and how the American Dream might now be about perfection rather than acquiring goods or status. One key aspect of this Dream is housing, often viewed as a single-family house in a suburb. A new report from the National Association of Realtors suggests homebuyers now have some new preferences:

The 2011 Community Preference Survey reveals that, ideally, most Americans would like to live in walkable communities where shops, restaurants, and local businesses are within an easy stroll from their homes and their jobs are a short commute away; as long as those communities can also provide privacy from neighbors and detached, single-family homes. If this ideal is not possible, most prioritize shorter commutes and single-family homes above other considerations.

1. The economy has had a substantial impact on attitudes toward housing and communities…

2. Overall, Americans’ ideal communities have a mix of houses, places to walk, and amenities within an easy walk or close drive…

3. Desire for privacy is a top consideration in deciding where to live…

4. But, having a reasonable commute can temper desire for more space…

5. Community characteristics are more important than size of home…

6. Improving existing communities preferred over building new roads and developments…

7. Major differences in community preferences of various types of Americans…

All of these points are from the executive summary which also has some key percentages for each point.

The results of this survey seem similar to a recent report (see here) earlier this year from the National Association of Home Builders that suggested Generation Y wants more urban settings and more social (and smaller?) homes. In the long run, it remains to be seen whether these changes are broad cultural changes, generational changes (driven by younger generations), or opinions changed primarily by recent economic conditions.

Richard Florida sums up the report this way:

We’ve come to a crossroads that neither dyed-in-the-wool sprawl advocates nor crunchy urbanists dreamed of two decades ago, in which the choice isn’t between urban and suburban but between neighborhood and subdivision. A great neighborhood is a great neighborhood whether it’s in the city or the suburbs. It’s not an either/or, between crowded apartments or Cape Cods on cul de sacs, it’s more of a blend. Developers and planners take note: there is a potentially enormous market in cities for narrow single-family houses on small lots, like you see in places like Santa Monica and Venice. And as I wrote in The Wall Street Journal not too long ago, there are countless ways that our suburbs can be densified and reinvigorated. The American Dream hasn’t died–it just looks a lot different than it did in the 1950s. It looks a lot different than it did a decade ago.

So this report may not really be a repudiation of the suburbs but rather a new vision for suburbia: private yet dense (with still a clear 80% preference for single-family homes) and with neighborhood amenities. I am a little surprised that there aren’t more specific questions about preferred housing size or housing costs. Additionally, the survey seems set up to ask a lot of questions about smart growth with little explanation why this was the main focus.

(A side note: the study was a web survey:

The 2011 BRS/NAR Community Preference Survey is a web-enabled survey of adults nationwide using the Knowledge Networks panel. Knowledge Networks uses probability methods to recruit its panel, allowing results to be generalized to the population of adults in the U.S. A total of 2,071 questionnaires were completed from February 15 to 24, 2011. The data have been weighted by gender, age, race, region, metropolitan status, and Internet access. The margin of sampling error for the sample of 2,071 is plus or minus 2.2 percentage points at the 95% level of confidence. A detailed methodology can be found in Appendix A.

Knowledge Networks (KN) is a firm that gets around some of the common problems of web surveys (typically having to do with having a representative sample) by having representative panels who take web surveys. In order to get a representative sample, KN employs this technique:  “Since almost three in ten U.S. households do not have home Internet access, we supply these households a free netbook computer and Internet service.”)

An office park that successfully created a “culture of public transit”

A lot of people would want more Americans to consistently use public transit. But one writer suggests a San Ramon, California office park where “33 percent of the park’s 30,000 workers leave their cars at home” might hold some answers. Here is a look at how this office park’s transportation center tackles logistics, focus on the multiple benefits of using public transit, and has “evangelistic zeal”:

1. Logistics: the office park was built in 1978 and needed to competed with other office parks. The office park purchased a fleet of buses, found ways to subsidize costs, and coordinated bus schedules with other nearby mass transit options. Today: “There are now 13 different bus routes running to the park, and the connections to BART and various local train and express bus services are coordinated. On its website, the Ranch now pitches its transit program as a competitive advantage.”

2. Pitching the multiple benefits of public transit: it’s not just about money but improving health and reducing stress. Today:

Marci says that once riders begin leaving their cars at home they go through a stressful period of two weeks or so where they feel that they’ve lost the control they had in the car. But within three weeks they notice their overall stress levels are lower. “Transit requires that you go at a different pace. You have to wait. If there were roses, we’d smell them,” she says, “There’s not much of that in our lives.” She says HR people have called her saying some of their meaner workers have become pleasant people after switching to transit.

3. The office, particularly its program manager, aggressively push the program and look to engage people in conversations.

Overall, this sounds interesting. But I am a bit skeptical about whether this is a possible solution to energy and transportation issues:

1. Even with all of this work, 67% of the workers still use their cars on a regular basis. (This is based on data the story provides.) Is this the best we can hope for outside of really dense urban areas like New York City? It really is difficult to fight a culture that prizes individuals being able to drive themselves.

2. There is no mention in this article about the cost of this program. It could be cheaper in the long run (if all the possible costs are accounted for) but I imagine some money might need to be spent up front for similar programs with the reduced costs coming down the road. The article suggests this program helped this office park compete – how much did it help?

3. Is this three-pronged strategy viable on a larger scale? Or does it only work under certain conditions?

“Invasion of the Harry Hunters”

When reading a story today about the upcoming Royal wedding, I was reminded of a Newsweek piece from several weeks ago. While it may not be surprising that some young British women might be trying to catch the attention of Prince Harry, it is more interesting to read about young American women who have become “Harry hunters”:

Fleming is part of a small but resolute group of American “Harry hunters,” aspiring princesses who are crossing the ocean in hopes of capturing the redheaded royal’s heart (and the tiara that comes with it). Some rely on semesters abroad to lend an air of social normalcy to their excursions, while others simply count their pennies—or lean on their parents—to fund extended vacations in Britain. But the goal is always the same: to live happily ever after with a prince of the realm.

These days, their mission has taken on a distinct sense of urgency. Next month Harry’s older brother, Prince William, will wed Kate Middleton—a commoner herself, the Harry hunters note optimistically. But even as these earnest, young crown chasers devour royal-wedding news, the nuptials are a source of serious anxiety. When it comes to available slots on the Windsor family tree, explains author Jerramy Fine, whose 2008 memoir recounts her own unsuccessful efforts to marry into the monarchy, “Harry is now their last chance.”

This reality is not lost on Taylor McKinley, a sweet 21-year-old George Mason student who recently began a semester abroad at the University of Leicester (two hours outside London). McKinley takes her princess prep seriously. She reads magazines with names like Majesty and Royalty. She studies the historical monarchy. And in high school, she even abstained from dating, figuring she would “hold out for royalty.” Now, she spends her weekends dragging classmates to Harry’s favorite restaurants and waiting for fate to strike. Her parents are skeptical, but McKinley is confident she will one day find her prince. “I’m one of those people who only reads books with happy endings,” she says.

McKinley’s tactics are mild for a Harry hunter.

How come the story doesn’t include any reactions from family or friends of these girls? While these girls supposedly take heart that Kate Middleton is a “commoner,” in order to be a “Harry hunter,” it seems like one has to be rather wealthy and have time on her hands. Studying abroad is a clever tactic but the story also discusses a woman who works part-time and takes her summers abroad to try to catch Harry’s eye. I know “commoner” means “non-royal,” but it is not like just any American young woman could fly to Britain and attend the sorts of events that Prince Harry might be at.

I wonder if we will hear more about the story in the next few weeks as we get closer to the wedding date. I’m sure we’ll hear theories or ideas about why a good number of Americans seem to be fascinated by a foreign country’s royalty.

UPDATE 10:09 AM 4/13/11: One more thought came into my mind about this story:

The news story gives us two examples of American women that are doing this and then says little about how many people are actually doing this. We get two small clues. Regarding the American women, we are told these two are  “part of a small but resolute group.” Regarding British women, we are told that “London’s Daily Mail frequently chronicles the exploits of young British socialites who spend weekends trolling the prince’s favorite bars.” While this may be an interesting story that grab’s people attention (like me), if there are only 5 or 15 or 25 people doing this, does it matter?

This is an example of a type of story that bothers me as a social scientist. It is interesting but it seems to be based on two cases with little attempt to ascertain whether this is a broader trend or not.
