I wrote recently about population density and its relationship to voting behaviors. In the 2012 election, high population density correlated with votes for Obama, while low density correlated with votes for Romney.
Others observed that red states have more traffic fatalities than blue states. This is fairly easy to explain, as red states are lower density than blue states and people necessarily spend more time in cars than in the cities of blue states.
Some suggested that race is more important and proposed some version of “white people vote for white people, black people vote for black people” as the simpler explanation. But this notion has always struck me as simplistic.
So I decided to dig in to voting behaviors by examining racial composition and the 2012 election results at the county level.

Any significant level of diversity seems to trigger liberal voting behavior. At 9% Hispanic population (or just 3% Asian population), people vote blue. Think about that for a second… if your county has just a 3% Asian population, it most likely voted Democratic.
So Do People Vote by Race?
The data show that when the percentage of black population exceeds 39%, Obama receives the bulk of the votes. This would indicate that yes, black people do often vote for black people, which by itself is not that informative. But Asians and Hispanics also apparently vote for black people as well.
Above about 55% white population, counties overwhelmingly voted for Romney. But up to 45% white population, votes went to Obama.
The real drivers seem to be density and diversity. Density (such as found in cities) corresponds with diversity. Diversity leads to progressive voting behavior.
It’s simplistic to think that it’s all about identity. White voters didn’t all vote for Romney, black voters didn’t all vote for Obama, and Hispanic and Asian candidates overwhelmingly supported Obama. There is no particular reason to think that an Hispanic Republican candidate can win by running on the same old platform.
To succeed, both parties need to run candidates that will appeal to the population in America’s increasingly diverse and dense cities.

I’ll be writing more about the correlation between population density and voting behaviors, but in the meantime check out these maps showing participation in the 2012 election. (Darker areas voted more than lighter areas.)
So the country voted. Some parts more than others.
What I think is interesting is that much of middle America, particularly in the middle-south, didn’t vote as heavily as people in the north. (The Appalachia/Ozarks belt?) California’s central valley also voted pretty lightly.
A few places turned out in BIG numbers (85-90%). Hard to say what might be going on there, but in general I’d say those people are the most annoyed and felt like they needed to vote.

The 2012 election demonstrated what many people could have guessed: rural states voted for Romney while densely populated states voted for Obama.
Many have offered explanations — everything from the presence of top universities in cities, to the prevalence of immigrant and African American populations. Perhaps the Republicans should consider running a Hispanic or African American candidate in 2016; but will that really help? Is identity the issue, or is it more about values?
Or is something more basic at work? Studying election results county by county, a stunning pattern emerges.
Population Density: the Key to Voting Behavior?
Curious about the correlation between population density and voting behavior, I began with analyzing the election results from the least and most dense counties and county equivalents. 98% of the 50 most dense counties voted Obama. 98% of the 50 least dense counties voted for Romney.
This could not be a coincidence. Furthermore, if the most dense places voted overwhelmingly for Obama, and the least dense places voted overwhelmingly for Romney, then there must be a crossover point: a population density above which Americans would switch from voting Republican to voting Democratic.
So I normalized and graphed the data, and there is a clear crossover point.
At about 800 people per square mile, people switch from voting primarily Republican to voting primarily Democratic. Put another way, below 800 people per square mile, there is a 66% chance that you voted Republican. Above 800 people per square mile, there is a 66% chance that you voted Democrat. A 66% preference is a clear, dominant majority.
So are progressive political attitudes a function of population density? And does the trend hold true in both red and blue states?
Red States and Blue States
Separating the results from red states and blue states, we can see that while each has a slight preference for mobile casino real money no deposit their ultimate candidate of choice, on a local level voting behavior is still directly correlated to population density.
Studying this graph, two important facts are revealed. First, there are very few cities in red states. Second, the few dense cities that do exist in red states voted overwhelmingly democratic.
Atlanta, New Orleans, St. Louis, Dallas, and Indianapolis are all in red states — and they all voted blue. And there are no true “cities” in red states that voted red. The only cities in red states that didn’t vote blue were Salt Lake City and Oklahoma City. And by global standards, they are not really cities — each has population density (about 1,000/sq. mi.) less than suburban Maryland (about 1,500/sq. mi.).
Historically, one can argue that red states have disproportionately affected election results by delivering a material number of electoral votes.
Red states simply run out of population at about 2,000 people per square mile. St. Louis is the only city that exceeds that density in a red state. It voted overwhelmingly Democratic (82.7%). In contrast, blue states contain all of the country’s biggest and densest cities: Washington DC, New York City, San Francisco, Baltimore, Milwaukee, Philadelphia, Boston, etc.
Red States Are Just Underdeveloped Blue States
As cities continue to grow in red states, those cities will become more blue, and ultimately, those states will become more purple, and then blue. The Republican party says it’s about growth and prosperity; the best way to achieve that in red states is through the growth of cities.
If you follow the red state trend lines, you can clearly see that any dense, fast-growing cities that might emerge in red states will be very likely to vote blue. The few that do already exist already vote blue. How would these new cities be different and cause them to vote red?
Red state voters generally prefer low-density housing, prefer to drive cars, and are sensitive to gas prices. Once population density gets to a certain level, behaviors switch: high-density housing is the norm, public transit becomes more common, and gas use (and price sensitivity) drops.
Red state values are simply incompatible with density.
Cities Are the Future
Globally, cities are growing rapidly as people move from rural to urban areas in search of opportunity. By 2030 it’s estimated that cities will grow by 590,000 square miles and add an additional 1.47 billion people.
Only subsidized suburban housing and fuel prices are insulating the United States from this global trend, and even with these artificial bulwarks, there is no good reason to think that America’s future lies in low-density development.
Density is efficient. Density produces maximum economic output. An America that is not built fundamentally on density and efficiency is not competitive or sustainable. And a Republican party that requires America to grow inefficiently will become extinct.
While the Republican party is retooling in the desert, it should carefully consider whether its primary issue is identity politics or whether its platform is simply not compatible with the global urban future. If that’s the case, an Hispanic candidate running on the same old Republican platform will simply not resonate. The Republican party must develop a city-friendly platform to survive.
Cities are the future and we need candidates from both parties that understand that reality.
The next question: why does population density produce these voting behaviors? Is the relationship causal or correlated? Probably both. I’ll explore this in my next post.

November 5th, 2008 — economics, politics, trends
I may not exactly be what you’d call a futurist, but I do spend a lot of time thinking about the future and the evolution of ideas.
Since 2001, our country has been a breathing anachronism — a zombie-corpse of outdated ideology and backward-looking worldviews — living in a state of Cold War suspended animation, pushing outdated agendas and peddling simplistic platitudes to an indifferent world which had increasingly moved on to other things and the urgent business of reality.
Yesterday, we said “enough” to sticking our heads in the sand. Yesterday, we said “no” to “drill baby drill,” and “yes” to a real and sustainable energy economy. And yesterday, we showed the world that the America that they love — the America that its founders had hoped it would become — is back, functioning and healthy.
I’m not naïve enough to think that one political party or another will magically take the country in the right direction. In fact, now is when the real work of shaping policy through direct political action will need to begin. The battle is not over now. You must participate to get the kind of country you want to live in, and that’s true regardless of who is in office.
But, one thing is true: leadership matters. And at this time of transition and change, America desperately needed a leader with imagination, hope, and a sense of the future. And we have that leader in Barack Obama. He has singlehandedly rewritten the rules of presidential politics in America and has proven that he is the political heir of both Kennedy and Reagan. Barack Obama has brought hope back to America and the world. With Barack Obama, the 21st century begins in earnest.
As children, we were all sold a vision of the future, and this was supposed to be it. We were supposed to be rocketing around with jetpacks, with robot assistants and TV watches. By the year 2000, children imagined their lives would be studded with space age marvels. But, 2000-2008 has felt more like the final cold grasp of a 20th century that has outlived its welcome; a sick and disordered hallucination of the century that wouldn’t die.
I remain a student of history, and I am thoroughly ready for the 20th Century to pass into the history books, and now, packed up and archived along with the last 8 years which are rightfully its, I send it on and bid it farewell. 20th Century, go to sleep; really deep; we won’t blink.
2009 is the new 2001. Welcome to the future.
