age/aging

This graph, from Flowing Data, shows the obesity rates of different generational cohorts as they age.  Each differently colored lines represents people who were born in different decades (between 1926 and 1935 and on up).  Ascending lines represent higher percentages of obesity.  Horizontal progress represents age.

So, first things first: rates of obesity go up as a cohort ages.

What else?

People born after 1975 are starting out with higher rates of obesity than people born between 1956 and 1975.

And.

Obesity rates seem to rise at a pretty consistent rate as cohorts age.  So, if a cohort starts out with a high rate of obesity, they will have an ever higher rate 10 years later, and an even higher rate ten years after that, and so on.

The consequence:  Higher rates of obesity overall for each cohort that follows the last.

The data for the most recent cohort, born between 1996 and 2005, however, looks like it might be bucking the trend.

Tom Schaller recently posted over at FiveThirtyEight about a new Hyundai commercial. The commercial suggests that you need to get a safe car because of all the young drivers on the road:

Here’s another:

Schaller argues that, while the commercials may be entertaining enough, he can’t help but wonder how people would react to similar commercials mocking the other age group over-represented in accidents — the elderly, according to the Insurance Institute for Highway Safety:

Is Hyundai wrong to say that teens, particularly those who just got their licenses, are more dangerous drivers than other age groups? No. But though people might joke about elderly drivers, I agree with Schaller — I can’t imagine a company putting out ads with a similar mocking tone and not immediately getting a ton of negative feedback ending in pulling the commercials and apologizing.

And this likely has a lot to do with the fact that older Americans are organized and represented by groups like the AARP and are thus able to wield political pressure and protest negative portrayals in a way that teens aren’t. This doesn’t mean that older people don’t get mocked (especially in TV shows and movies), but that a company is likely to be much more afraid of insulting them than insulting 16-year-olds.

The Pew research foundation recently released some data comparing generational cohorts.  Data on the acceptance of interracial dating shows that acceptance is increasing among all groups and is higher for each successive cohort:

C.N. Lee, at Asian Nation, interprets:

I am also not surprised that the Millennials are the most supportive of interracial dating, as the graph illustrates. However, in looking at the graph, it shows that somewhere around 2007, the approval rates for interracial dating actually declined slightly for Baby Boomers, Generation X, and the Millennials. Further, at this point, we do not yet know whether the approval rate for interracial dating will continue to decline, or whether it will rebound and continue its upward trajectory.

This is the second post using material borrowed from the essay, “Facts and Fictions About an Aging America.”  Our online host, Contexts magazine, is offering some free content, including this essay, now through March 15th.  See yesterday’s post here.

While people in industrialized countries live longer and healthier lives than ever, more educated people enjoy even less morbidity than less educated people.  The figure below illustrates the decline in mental and physical function over time for people with a college degree, a high school degree, and no degree at all:

The figure shows that more educated people experience “excellent health” than less educated at every age, except perhaps 85 and above.  Why might this be?

Well, higher educated people may come from wealthier families who were able to provide their children with health care, good nutrition, and exercise.  Having degrees may also correlate with jobs that are less harmful to the body and offer both health insurance and more free time to exercise.  Lower educational attainment is likely correlated with economic insecurity; a lifetime of struggling to make ends meet could create the kind of bad stress that interferes with both mental and physical health.

Other theories?  Thoughts on these?

Our online host, Contexts magazine, is offering some free content, a selection of essays on aging, now through March 15th.  I borrowed the material below from the essay, “Facts and Fictions About an Aging America.”

The average American is aging… and fast.  Advances in public health — especially related to childbirth, infant mortality, and infectious disease — have led to longer lives.   “The result is that death has been permanently shifted from a phenomenon among the young to one of the old.”  This means that the age distribution in the U.S. has shifted from one shaped like a neat pyramid (in 1900), to one shaped kind of like a house (in 2000), to whatever shape that is they’re predicting in 2050:

The great news is that “active life span is increasing faster than total life span.”  That is, even though we live longer, we spend fewer of our years sick or disabled than ever before.  This is called (so you can impress your friends) the “compression of morbidity.”

Claire P. and Jessica Sherwood, of the Sociologists for Women in Society, sent in a link to some data, from OK Cupid, on women’s preferences for frequency of sex by county.  The uptake: Women’s preferences for the incidence of sex goes up as they age.  You can check out the interactive map, or just check out my screen shots below.

Preferences at age 20 (red = higher preference for once a week; blue = higher preference for once a day; white = in the middle):

Preferences at age 25:

Preferences at age 30:

Preferences at age 35:

Preferences at age 40:

Also from OK Cupid: the racial politics of dating, what women want, and men’s preference for younger women.
