Update on Guam

Eight years ago this month, we at Twenty-One Debunked were chagrined when Guam unfortunately raised the drinking age from 18 to 21.  We have enough data to give some sort of an update on Guam since the drinking age was raised, and we see that the results were at best a mixed bag overall.

At least one Guam news website since then has trumpeted the July 2010 law change as a success.  For example, they note (correctly) that according to the 2011 Youth Risk Behavior Survey (YRBS), 13.6% of Guam's high school students engaged in "binge" drinking, compared to 19.2% in 2007, the last available year in the survey before the law change.  This drop by nearly a third sounds impressive until you consider the following facts:
  1. The decline in high school "binge" drinking actually began in 2001, from a high of 24.9%.  The drop from 2001 to 2007 was almost as large as the drop from 2007 to 2011.
  2. The figures also declined in the nation as a whole, from 29.9% in 2001 to 26.0% in 2011 to 21.9% in 2011.
  3. Due to the fact that the surveys were not done every year, we have no idea when the decline in Guam began to accelerate.
  4. For grades 9 and 10, the differences in "binge" drinking rates between the years 2007 and 2011 were not statstically significant, despite the fact that the differences were significant for the nation as a whole. 
  5. In fact, 9th and 10th graders in Guam actually saw increases in self-reported riding with a drinking driver, while the mainland saw decreases.  So much for the trickle-down theory.
  6. Guam's teen drinking and "binge" drinking rates have been consistently below the national average, even when their drinking age was 18.
  7. Compared with 2007, high school students in Guam saw increases in boozy sex as well as unprotected sex in 2011.
  8. While the overall decline in teen drinking did continue in recent years in Guam, we must keep in mind that Puerto Rico (drinking age 18 unchanged) and Northern Mariana Islands (drinking age 21 unchanged) also saw similar declines as well.
As for whether there were any effects on drunk driving arrests or crashes, at first it was too soon to tell since 2011 and 2012 data were not yet available right away.  Even the 2010 data were problematic since the drinking age changed in midyear and there were not enough age-specific data yet for alcohol-related crashes and deaths.   But several years later, we now have enough data to conclude that raising the drinking age in Guam did NOT save lives, since the number of DUI deaths (in total and among people under 21) did not decrease, and in fact even increased a bit since the law change.

We had previously noted the Uniform Crime Report for 2010.  In it we see that total DUI arrests dropped significantly from 2009 but nonetheless remain higher than 2008.  DUI arrests for 18-19 year olds were 42 in 2008, 52 in 2009, and 35 in 2010, which was a slight decrease from 2008.  (Data for 20 year olds in 2010 was lumped in with 21-24 year olds, so it could not be used.)  Juvenile crime (i.e. under 18) saw zero progress overall in 2010, and in fact nearly doubled from 2009.  Specific crimes that rose in 2010 among juveniles included not just DUI but also murder, rape, assault, robbery, vandalism, liquor law, and drug abuse violations among others.

One must also remember that in 2010 Guam had a major crackdown on drunk driving with tougher new penalties (after many years of a very lax policy), and also increased education and awareness about the alcohol problems on the island.  Also, the new drinking age of 21 appears to be more heavily enforced that the previous drinking age of 18, which was poorly enforced.  That's a lot of variables to consider.

The most recent Uniform Crime Report for Guam was for 2016, and the data show that there were 17 DUI arrests for 18-19 in 2015, about half the number there were in 2010. Apparently, data were rather spotty for the years in between.  That said, the number of DUI deaths nonetheless went up from 2010-2013 before dropping again through 2015, so it would be facile and fatuous to link this longer term trend to the drinking age hike.  More likely it was due to increasing crackdowns on DUI in general.

Finally, we should note that if Miron and Tetelbaum's groundbreaking study of the 21 drinking age is any guide, any apparent benefits of Guam raising the drinking age to 21 should disappear beyond the first year or two of adoption.  And while tourism actually went up in 2011 (except for Japanese tourists after the tsunami) contrary to our predictions, and reached a record high in 2017, one could argue that Guam was simply lucky due to a confluence of other factors.  For example, the US military buildup on the island generated increased economic growth that could have potentially masked (or delayed) any declines in tourism that would have otherwise occurred.  The Fijian experience is instructive in that it took fully three years for Fiji to see that tourism was suffering due to the 2006 drinking age hike to 21, and then it was lowered back to 18 in 2009.  And now that Guam has raised the smoking age to 21 as well in 2018, they are really pushing their luck in that regard now.

Update on Guam

Two years ago, we at Twenty-One Debunked were chagrined when Guam unfortunately raised the drinking age from 18 to 21.  While not all the necessary data are in yet, we have enough preliminary data to give some sort of an update on Guam since the drinking age was raised.

At least one Guam news website trumpets the July 2010 law change as a success.  For example, they note (correctly) that according to the 2011 Youth Risk Behavior Survey (YRBS), 13.6% of Guam's high school students engaged in "binge" drinking, compared to 19.2% in 2007, the last available year in the survey before the law change.  This drop by nearly a third sounds impressive until you consider the following facts:

More About Guam

As you already know, much to our chagrin Guam was in the news for hastily raising the drinking age to 21 in July 2010.  That makes them the first part of the USA to change the drinking age in over two decades.  They were in the news again recently in August.  The first is that they will actually get tougher on DUI by requiring a mandatory overnight jail stay and will prosecute cases within 48 hours, instead of the former policy of "catch and release" that made it such a joke before.  (This we certainly applaud, by the way.) The second was the fact that the arrest rate for DUI had been skyrocketing since 2007, especially for younger drivers.  Aside from being the major impetus for the latest change in DUI criminal procedure, this fact was also used by some to retrospectively justify the drinking age hike to 21.

But the latter claim does not stand up to closer scrutiny.  In fact, it falls flat on its face.  The stats from the Guam Police Department show the following numbers, in a population of about 175,000 residents:

YearTotal DUI ArrestsUnder 21%  Under 21
2007790587.3%
20086777010.3%
2009114611610.1%
2010 (first half)3824110.7%

Clearly arrests have risen for all ages, and doubled for those under 21 in two years, though the share of arrests under 21 has essentially plateaued since 2008, after jumping from 2007 to 2008.  Back in 2005, it was only 6%.  However, arrest rates can be quite deceiving, as the table of fatalities below so clearly shows:

YearTotal FatalitiesAlcohol RelatedUnder 21% Under 21
2007241119%
20088500%
2009139111%
2010 10200%
Avg. 15.77.70.577.4% (3.7%)

Here we see a very different picture indeed.  It does not appear that alcohol-related fatalities have been rising for any age group.  Quite the opposite in fact, a whopping 64% decrease overall, and thus the reason for rising arrests is most likely greater enforcement and targeting of younger drivers, as opposed to more drunk driving. You read right that in 2008 and 2010, there have actually been zero traffic fatalites of those under 21.  The 2010 data only include the first half of the year (up to June 30), during which the drinking age was still 18, so one can thus project 20 total deaths and 4 total alcohol-related deaths for the whole year, and either zero or one death under 21, had the status quo remained. 

As for the percentage under 21, since alcohol involvement is not given for the under 21 data, we assumed the worst (that all of them involved booze) and calculated the number of under-21 deaths as a percentage of total alcohol-related deaths.  This gives 7.4%, but if we assume that half of the under-21 deaths involve booze (a reasonable estimate given the all-ages data), we get a mere 3.7%.  Thus, drivers under 21 are overrepresented in arrests, but underrepresented in fatalities.  Put another way, even if all under-21 drinking was to somehow magically disappear, over 96% of the deaths would most likely still occur.

How does this compare with the rest of the nation, where the drinking age has been 21 since 1988?  Well, research shows that in 2008, drivers under 21 accounted for 12% of total fatalities and 13% of alcohol-impaired fatalities.  Clearly worse than Guam by any measure, but remember that 21-24 year olds are the worst of all in terms of overrepresentation in drunk driving deaths, a fact that is true in almost every developed nation in the world regardless of drinking age.  Thus, these data are hardly a ringing endorsement for a 21 drinking age.

Guam Raises Drinking Age to 21

We didn't think this would actually happen, but it did.  On July 8, 2010, the bill that raised the drinking age to 21 was unfortunately signed into law at noon.  This new law, effective immediately with no grandfather clause, criminalizes the purchase and possession of alcohol by anyone under 21, just like it was for those under 18 before, except that 18-20 year olds are still allowed to work in bars and sell/serve alcohol.  Selling to anyone under 21 is illegal now as well. 

This time, they did not even leave it up to the people.  (Not like those over 21 really should have a say as to what legal but outvoted young adults 18-20 put into their own bodies, especially if those over 21 are allowed to do it themeslves, but it still was elitist for the legislature to go over the people's heads.) It was passed unanimously by the Guam Senate with almost no debate at all, in spite of the fact that referenda for raising the drinking age in previous years (such as 2006) had failed.  What little discussion occurred was primarily recycled and often outdated junk science from the mainland, combined with shaky (but emotional) anecdotal evidence from Guam.  The deck was stacked, and the opposition didn't stand a chance.

We predict that, based on research we have previously cited, no lives will be saved as a result of this draconian law, at least not in the long run.  They would have been better off getting tougher on DUI and raising the alcohol taxes than punshing all 18-20 year olds for the actions of the few.  Like we previously noted, 94% of the island's DUI problem consists of drivers over 21, and would still remain even if they could somehow prevent everyone from drinking until 21.  On the mainland, roughly 90% of young adults will drink before 21 despite the drinking age, so even that is just wishful thinking. 

Also, this will most likely hurt Guam's economy, dependent on tourism as they are.  Looks like tourism will probably decrease over there, while it will likely increase in Puerto Rico and the Virgin Islands, the last two places in the USA in which 18-20 year olds are allowed to drink legally, and no passport required.  Fiji learned this the hard way in 2006-2009, when their drinking age was briefly 21.  They have since lowered it as a result, and the sky did not fall.  Thus, we hope the leaders of Guam will come to their senses within a few years as well after seeing that the costs of an unrealistically high drinking age outweigh any possible benefits.

To Guam: Don't Raise the Drinking Age!

Guam (Guahan) is one of the few places in the United States that, along with Puerto Rico and the Virgin Islands, still has a drinking age of 18, but all that may soon change.  Several politicians on the island want to raise the drinking age to 21, and the majority of adults (who are over 21) agree as well.  They claim it will make the island safer and reduce various social problems.  But we at Twenty-One Debunked feel that this move is a huge mistake.

Supporters of the proposed 21 law ignore several important facts while simultaneously touting junk science.  First, Guam (as well as Puerto Rico and the Virgin Islands) has lower teen drinking and past-month "binge" drinking rates than the mainland, as well as lower than the Northern Mariana Islands, where the age limit is currently 21.  Ditto for self-reported driving after drinking in the past 30 days, according to the latest CDC's Youth Risk Behavior Survey data:


Location"Binge" Drinking
(Grade 12)
Drove after drinking
(Grades 9-12)
MLDA Year
USA (overall)36.5%10.5%212007
Puerto Rico (USA)33.2%7.3%
18
2005
Guam (USA)30.3%7.8%182007
Northern Mariana
Islands (USA)
36.5%14.1%212005
US Virgin Islands14.4%6.1%182003
American Samoa26.1%7.8%212007

In addition, only about 6% of all drunk driving arrests in Guam are for drivers under 21.  That means that even if you could somehow magically stop everyone from drinking until 21, 94% of the island's DUI problem would still remain.

Secondly, Canada has seen the same (or faster) decline in traffic fatalities as the United States despite not raising the drinking age to 21, and their teen "binge" drinking rates in most provinces remain comparable to the geographically and demographically similar northern States as well.  In fact, most of the world allows 18 year olds to drink, without the sky falling in those countries. 

Thirdly, if Guam thinks that a drinking age of 18 is not working in some way, the first thing that should be done is to enforce it (and other existing laws, such as DUI) better, not to ban all 18-20 year olds from drinking and thereby increase the number of "underage" drinkers.  Also, jacking up the alcohol taxes (especially beer) would likely be beneficial as well, especially if the funds are used for education, treatment, and law enforcement.

Fourthly, it will merely force drinking by young adults underground, as well as create "forbidden fruit" and "feast or famine" mentalities about alcohol.  This will make it a lot more dangerous than it has to be.  The effects of a 21 drinking age are thus iatrogenic--the "cure" is worse than the "disease."  This is part of the reason that several college presidents want to lower the drinking age to 18 on the mainland, even as the pro-21 folks are calling for more and more ancillary laws and pharisaical enforcement to prop up the greatest alcohol policy failure since Prohibition.  And we all know how that worked out.

Finally, 18 year olds are legal adults, for better or worse.  If you're old enough to go to war, you're old enough to go to the bar.  And those that claim that the brains of 18-20 year olds are not developed enough to be given full adult rights need to think long and hard about the underdeveloped ethics of trying them as adults, executing them, letting them be police officers, letting them get married and raise their own children, among other things--all while denying them sovereignty over their own bodies.  Makes you wonder how capable the brains of people over 21 (especially over 25) are of thinking in new ways.

To Guam, take it from us folks on the mainland:  21 does NOT work!  On the contrary, those that claim that it does and advocate raising the drinking age are playing with fire.
