the boston article, i really dont get it... there are 22 millions *spanish* in the us? how can it change 25 pct of the us racial breakdown ? people are increasingly "white" ? does the guy realize how the view he puts in Franklin's mouth are complete historical non sense if he considers a bit of non us history.. ? and then one day races do not exist and that will be heaven, what ?

the guy's supposedly only conservative in the boston globe, may be that is why he tries to outBS his audience..

The sloppy approach to statistics that leads to pie charts extends to sloppy analysis of those pie charts.

Robert Kosara

I think your criticism would have been moot if you had bothered to mirror what these articles do, which is compare the projected situation in 2050 with today. Currently, the US population is made up of about 80% non-Hispanic whites, so all the other races/ethnicities only make up a total of 20%. That is an absolute majority, and a large one at that.

The projection says that by 2050, whites will no longer have that absolute majority, and that is a big change. That will have huge implications on the kind of politics made in this country, the culture, language (think the discussion about making English the official language was stupid? You ain't seen nothing yet!), etc. The US are clearly dominated by white anglo-saxons right now, and the changes that are bound to happen will not go over quietly, and there will be a lot of resistance.

Of course, these overall statistics never describe every place the same way. The city where I live is about 35% black and slightly less than 50% non-Hispanic white right now. A cut from 4 out of 5 to 2 out of 5 white people across the country will mean huge changes, making white folks a rather small minority in many places.

So I completely disagree with your analysis. The definition of a majority is unambiguous, and there are terms for what you describe (absolute and relative majority, plurality vs. simple majority, etc.). The pie chart here works perfectly well by showing the relative sizes of different groups that make up the entire population. The rest is a comparison with where we are right now, and the realization that that will have consequences beyond the angles on a pie chart.

Robert: I'm not arguing the point that there will be drastic and discomforting changes. I'm saying that the statement "whites to lose majority status by 2042" is much more responsible than the statement "2042 to see a white minority". Both statements are true but not equal. This is a common theme in statistics: there are many true statements that paint a partial and thus misleading picture of the underlying data. Simpson's paradox is one famous example.

Using this type of logic, we are led to conclude that the U.S. is a minority sports power since it won less than 50% of the Olympic medals, and that the collection of countries not called U.S. is the majority power. Completely nuts, in my book.

How about:

V. Type A represents a plurality?

Less tortured--more correct!

I haven't looked at the referenced Census press release or data, but I'll say a couple of things anyway.

One point is alluded to in the mention of a Boston Globe column: that Hispanic isn't a race. The current standard on data collection of race and ethnicity is to collect *two* separate pieces of data: Ethnicity (Hispanic / non-Hispanic) and Race (a pick from a short list). Some versions of Race identification use a "multi" category, while others do not. Generally, even those that do use multi don't track the components of that multi-race. So, someone can be Hispanic *plus* something else, or non-Hispanic plus something else, but there wouldn't be tracking of say Asian plus something else.

There's also a self-identification issue. I've seen data for twins where one twin was coded "black" and the other twin was "white". I'm guessing both are really "multi". The identification sometimes changes from year to year, too, for various reasons.

As in this analysis, there is the question of how to combine data on Ethnicity and Race. Often, when the data are combined, Hispanic trumps Race, so the race categories are effectively a disaggregation of non-Hispanic. If it's not combined into one data point, then it's typically an attempt to (as was mentioned above) identify the white/non-white split.

I can't say I agree with attempts to focus on the Hispanic/non-Hispanic split and disaggregations any more than I'd agree with a focus on a White/non-White split.

I'll also note that even here, where even the anti-piechart folks think a piechart might have something to say, piecharts are misleading. While they could be used to effectively demonstrate the reduced percentage of whites in the country, it doesn't show that it's primarily because the projected pie is bigger -- other categories than non-Hispanic whites are projected for faster growth in the coming years.
