Some big cities only made possible by air conditioning?

This seems pertinent with the recent heatwave in the Midwest and East Coast: how many of the major cities of the world wouldn’t exist without air conditioning?

It wasn’t until the beginning of World War II that homes in southern U.S. cities began using air conditioning units. By 1955, one in every 22 American homes had air conditioning. In the South, that number was about 1 in 10, according to the historian Raymond Arsenault [PDF]. Since this increase in air conditioning use, many of these Southern cities experienced a population boom.

I took a look at the metro areas in the U.S. with more than 1 million people and found which have historically been the hottest, based on the number of cooling degree days per year — a statistic used to measure how much and how many days the outside temperature in a certain location is above 65 degrees. Using numbers from NOAA, I found that between 1971-2000, six big cities in the South had an average of at least 3,000 cooling degree days. I also compared the 1940 metro population (when available) to the metro population in 2010. From the time just before air conditioning became popular in the South to today, population growth in the region has skyrocketed. This raises the question: would these hot Southern cities be around, at least in their present form, if air conditioning hadn’t been invented?

But, of course, there are bigger, hotter cities across the globe. In fact, seven of the largest metros in the world have an average high temperature above 90 degrees Fahrenheit.

Not surprisingly, all of these cities are found in developing countries. As Michael Sivak, a professor at the University of Michigan notes, only two of the warmest 30 global metros can be found in developed countries. With the middle class growing in warm metros in countries like India, demand for air conditioning is increasing. A recent New York Times article reported that sales of air conditioning units in India and China are growing 20 percent per year and are fast becoming a middle-class status symbol. Last year, 55 percent of new air conditioners were sold in the Asia Pacific region.

Is there some sort of giant control group we could use to figure this out? Over the weekend, I was in a 150 year old church with no air conditioning. It was hot though I think this was primarily because there was no air movement; indeed, when we walked outside afterward, it felt more pleasant as there was a slight breeze. Before air conditioning, people obviously survived in such temperatures (and also survived in the winters without central heating as we know it today).

So this seems to be the real question: could we expect that there would be major changes in population distributions if there was no air conditioning whatsoever? Would Florida really have few people and post-World War II Sunbelt expansion not taken place? The best solution to all of this would be to have people move to more temperate climates where it doesn’t get too hot in the summer or too cold in the winter. This generally requires consistent breezes, usually off major bodies of water. Of course, not everyone can live in places like Hawaii which only has a record high temperature of 100 degrees. Did the Mediterranean climate help give rise to empires like Greece and Rome (though it makes it difficult to then explain the Sumerian, Assyrian, Babylonian, and Persian empires which must have adapted to desert climates)?

More broadly, we could discuss the influence of ecology on population growth and state building. I remember studying the mysterious decline of the Maya in southeastern Mexico/Guatemala. More recent scholars have suggested some kind of ecological explanation, perhaps a drought, that led to increased contentious competition for dwindling resources.

Is the American Sun Belt boom over?

One of the biggest changes in the American population in the last sixty years has been the migration to the Sun Belt. But new data suggests that this boom may have come to an end:

Between 2007 and 2010, Florida lost more people to internal migration than it gained, for the first time since the 1940s. Nevada, too, which had been growing for decades, had a net migration loss of 30,000 in 2009. And Arizona had a net gain of just 5000, way down from 90,000 five years before.

Meanwhile, New York and California both saw their net losses shrink in 2009 by more than half since 2005.

The analysis, based on Census Bureau and IRS data, was conducted by the Carsey Institute at the University of New Hampshire.

What explains the shift? The Sun Belt states, of course, were hit hard by the housing bust that helped trigger the recession and its aftermath. The early aughts housing boom was responsible for much of the growth in places like Clark County, Nev., and Maricopa County, Ariz. in the first place.

But just as important, migration as a whole, which has been on the wane for three decades, has really tailed off since the downturn began.

The economic crisis has limited mobility across the United States, particularly for the less wealthy who are then more tied to existing jobs and homes.

It will be interesting to see whether this trend continues or (1) the Sun Belt will grow again in the future or, in a longer shot, (2) older cities in the Midwest and Northeast (“Rust Belt”) regain some of the population that shifted south and west. In other words, once people have some more freedom to move, what will they choose to do and what social forces will push or pull them in certain directions?

The problems with white stereotypes in movies like The Help and To Kill a Mockingbird

Here is an interesting take on how the presentation of white people in The Help (and To Kill a Mockingbird) obscures the existence of racial systems in the Jim Crow South:

This movie deploys the standard formula. With one possible exception, the white women are remarkably unlikable, and not just because of their racism. Like the housewives portrayed in reality television shows, the housewives of Jackson treat each other, their parents and their husbands with total callousness. In short, they are bad people, therefore they are racists…

To suggest that bad people were racist implies that good people were not.

Jim Crow segregation survived long into the 20th century because it was kept alive by white Southerners with value systems and personalities we would applaud. It’s the fallacy of “To Kill a Mockingbird,” a movie that never fails to move me but that advances a troubling falsehood: the notion that well-educated Christian whites were somehow victimized by white trash and forced to live within a social system that exploited and denigrated its black citizens, and that the privileged white upper class was somehow held hostage to these struggling individuals.

But that wasn’t the case. The White Citizens Councils, the thinking man’s Ku Klux Klan, were made up of white middle-class people, people whose company you would enjoy. An analogue can be seen in the way popular culture treats Germans up to and during World War II. Good people were never anti-Semites; only detestable people participated in Hitler’s cause.

Turner is arguing that the Jim Crow South was a system supported by much of Southern society of all social classes. In contrast, movies can portray racism as being the opinion of particular individuals or of people of smaller social groups. This “whitewash” perhaps helps us feel better today – only bad people were racists – and also reflects our own moral calculus where racists can’t be good people.

But we know from American history that this was not exactly the case. Many “virtuous” and celebrated Southerners supposed slavery and Jim Crow laws. And the North is also complicit: “sundown towns” were the norm and segregation were quite high (and still are). Overall, racism and discrimination still takes place within systems that require beginnings and maintenance provided by people living within the systems and also those in charge.

More blacks return to the south

In the Great Migration that covered much of the 20th century, millions of African-Americans moved to northern cities from the south in search of economic opportunities. With this influx, cities like Chicago were changed dramatically. But a new study suggests that this trend may now be working in reverse as blacks move from northern cities back to the south:

The economic downturn has propelled a striking demographic shift: black New Yorkers, including many who are young and college educated, are heading south.

About 17 percent of the African-Americans who moved to the South from other states in the past decade came from New York, far more than from any other state, according to census data. Of the 44,474 who left New York State in 2009, more than half, or 22,508, went to the South, according to a study conducted by the sociology department of Queens College for The New York Times.

The movement is not limited to New York. The percentage of blacks leaving big cities in the East and in the Midwest and heading to the South is now at the highest levels in decades, demographers say…

Some blacks say they are leaving not only to find jobs, but also because they have soured on race relations.

A few questions pop into my mind:

1. As the article suggests, this sounds like more of an exodus of the middle-class and above. How does this movement back south break down by income and education levels?

2. How exactly does racism and discrimination play into this? Is the situation in the South now preferable to what is happening in major Midwestern and Northwestern cities?

3. How surprising is this considering the population shifts in America over the last few decades to the South and the West?

Gated communities on HGTV

As someone who studies suburbs and housing, I admit enjoying watching people choose homes on HGTV on shows like House Hunters. I’ve noticed that one factor that occasionally influences the choice of homes is whether it is located in a gated community. A few thoughts about this topic, gated communities, which has attracted more attention from sociologists and planner in the last two decades:

1. On these shows, the gated communities often pop up in the South or West, particularly in Florida or California.

2. We rarely see any evidence of the gated community like the entryway to the neighborhood (a fake guardhouse or a real guardhouse?)  or a fence around the entire neighborhood. We are simply told that the suburban home is in a gated community.

3.  At least when making their choices on screen, the people rarely talk much about the fact that a home is in a gated community. This is probably due to the fact that the show is supposed to be about the home and not the neighborhood. (So how about a new show where it is less about the individual housing unit and more about selecting a neighborhood?)

4. The homes in the gated communities vs. those that are not in a gated community look very similar. Ultimately, it is really rare that anyone on this show is selecting a home that is in a “unsafe neighborhood.” As sociologists have suggested, living in a gated community is often a decision made regarding some amorphous outside threat. They are devices that portray a certain image while also acting as reassurance for residents. As some have shown, like Setha Low in Behind the Gates, some suburban residents feel very afraid even when they live in exclusive, upscale neighborhoods. The gates in many neighborhoods don’t really keep people out but they help the residents feel better.

MLK in Chicago

While many of the tributes to Martin Luther King, Jr. talk about the important marches and speeches in the early 1960s regarding civil rights (and the subsequent legislation), the last three years of King’s life are less well-known. Having grown up in the Chicago area, I was not aware that King spent a significant amount of time in Chicago in 1966 until I was doing some research in recent years. The Encyclopedia of Chicago has a brief summary:

But in the summer of 1965, the nature of King’s connection to Chicago changed. Responding to requests from local civil rights forces, King and the Southern Christian Leadership Conference (SCLC) joined the fight against school superintendent Benjamin Willis and Chicago’s segregated public schools. By the fall, SCLC had allied with the Coordinating Council of Community Organizations to launch a campaign to end slums in the city, which would become known as the Chicago Freedom Movement.

King relied on his lieutenant James Bevel to energize the first phases of the campaign, but in January 1966 he captured national headlines when he moved his family into a dingy apartment in the West Side ghetto. It was not until June that King and his advisors, under pressure to produce results, settled on a focus for the Chicago movement. King himself participated in two dramatic marches into all-white neighborhoods during a two-month open-housing campaign during the summer of 1966. These fair-housing protests brought real estate, political, business, and religious leaders to the conference table for “summit” negotiations.

In late August, King and Mayor Richard J. Daley announced that an agreement had been reached: the marches would stop, while city leaders promised to promote fair housing. King hoped that the “summit” accord would be an important step toward making Chicago an open city, but black militants denounced the settlement and the Daley administration never fulfilled its promises.

Several things are notable about this effort:

1. This was a large-scale movement in the North. Most depictions of the Civil Rights Movement imply that all the action or the problems that needed to be solved were in the South. This was not the case then or now. Indeed, measures of housing segregation show that the most segregated cities in terms of race are still in the North.

2. Even with the passing of Civil Rights legislation, this issue of housing discrimination and segregation is one that has plagued America. While the housing discrimination of today is less overt than that of the past (exclusionary zoning, differential treatment, and high prices today vs. redlining, blockbusting, and restrictive covenants in the past), King’s efforts are notable. Of his efforts in Chicago, King said something like “if we can solve the issue of housing in Chicago, we can solve it anywhere.” Chicago was notorious then for its segregation and this is still the case today.

3. Perhaps we don’t hear about these issues from King’s later years, such as housing or his thoughts about Vietnam or his efforts on behalf of labor, because they don’t seem to have clear solutions. Civil rights is an issue that seemed to have been solved with the Civil Rights Acts (though this isn’t quite the case). But housing is a long-standing concern in many cities and metropolitan areas. Viewpoints on Vietnam are still mixed and get brought up again in discussions of current wars.

4. This part of Chicago’s history is not one that is widely talked about. King and his followers led numerous marches in 1966 that were met with much resistance, particularly when marching in white neighborhoods. Chicago and the region has a longer history of negative incidents: one, in particular, in Cicero in the 1950s is often cited as a black family who moved into an apartment was met by an angry mob (including many housewives) who firebombed the apartment building. As the Encyclopedia entry suggested, the older Mayor Daley did meet with King but didn’t follow through on his promises. These sorts of moments are often scrubbed or ignored in history as they don’t reflect too favorably on communities. At the same time, we need to know about these to help understand the present reality.

The most and least Christian American cities

The Barna group has put together a report that includes the American cities with the most and least residents who identify as Christians. Here are the lists of the most and least Christian cities:

The cities (measured in the Barna research as media markets) with the highest proportion of residents who describe themselves as Christian are typically in the South, including: Shreveport (98%), Birmingham (96%), Charlotte (96%), Nashville (95%), Greenville, SC / Asheville, NC (94%), New Orleans (94%), Indianapolis (93%), Lexington (93%), Roanoke-Lynchburg (93%), Little Rock (92%), and Memphis (92%).

The lowest share of self-identified Christians inhabited the following markets: San Francisco (68%), Portland, Oregon (71%), Portland, Maine (72%), Seattle (73%), Sacramento (73%), New York (73%), San Diego (75%), Los Angeles (75%), Boston (76%), Phoenix (78%), Miami (78%), Las Vegas (78%), and Denver (78%). Even in these cities, however, roughly three out of every four residents align with Christianity.

It appears the report goes on to talk to talk about a few implications: this shows that even in the least Christian cities, around three-quarters of the people identify as Christians and the figures confirm some stereotypes about regions (the Christian South vs. the secular Northeast and West).

However, I had a different sort of question: is life in the more Christian cities qualitatively different than the life in the less Christian cities? Are the Christian cities marked by different actions or programs? Are people in the Christian cities more welcoming and are they more willing and active in helping those who need help? Would a visitor be able to know which cities were the more Christian based on interactions with its people versus other measures like the number of churches or religious advertising? Does the Christian faith of the individual residents translate into a different kind of community or local government?

And if the answers to these questions is “no, it really isn’t that different,” then why not?

Lower levels of segregation in many cities according to the American Community Survey

Residential segregation, primarily between whites and blacks, is a critical issue when considering the historical development and current state of American development patterns and way of life. But new findings from the most recent American Community Survey (the Census Bureau’s yearly survey) suggest that segregation levels have decreased in many cities:

Atlanta is one of several predominantly Southern and Western cities that showed a noticeable integration trend over the last five years as both middle-class blacks and whites moved into each other’s neighborhoods, according to the Census Bureau’s American Community Survey of 10 million Americans, released Tuesday…

Seventy-five percent of the largest 100 US metro areas showed neighborhood segregation rates slipping to levels not seen for more than a century…

Ethnic integration failed to show the same kind of gains…

It isn’t that the North, which has lagged behind the South and West in integration rates, has dramatically different attitudes on race. Rather, new housing and job opportunities in the South and West have helped to spur integration there.

This is interesting, and potentially uplifting, news. A number of sociologists have called attention to this issue in recent decades, perhaps most notably in American Apartheid published in the early 1990s. Recent maps show that many cities have a highly visible divide between different population groups. With these recent findings, the question may now be: how much more integration might we see in American cities? Is this a short-term trend or is this indicative of a slow, steady rise of integration in American cities?

What I would like to see is a more specific breakdown of what cities improved on integration and which did not. The article suggests that cities in the South and West had increasing rates of integration while segregation decreased less in the North. This is a reminder that in American cities, segregation has been more prominent in northern cities, what scholars (according to the article) call “the ghetto belt.” Are there lessons from the cities that improved in integration that can be exported to other cities?

Additionally, how have segregation/integration rates changed in suburbs or perhaps in whole metropolitan regions?

Learning about race from the South

The Christian Science Monitor has a story about seven lessons that can be learned about race from the South. Here is the list: “recognize how far we’ve come,” “talk about race like a Southerner,” (#3 is not listed in a heading but is something like “see the benefits of frequent interaction between blacks and whites”), “Blacks love Southern opportunity,” “don’t stereotype whites,” “segregation by any other name…,” and “keep moving forward.”

One thing that caught my attention: #6 discusses segregation in the North, a region which supposedly has been more favorable to blacks. Several academics dispute this notion:

“The concept of Southern exceptionalism has obscured a lot of American history and a lot of Southern history, and it’s time to put that to rest and understand how deeply interrelated America and the South is, and how much the two have always resembled each other,” says Larry Griffin, a sociology professor at the University of North Carolina, Chapel Hill, and author of “The South as an American Problem.” “For decades and decades, the South’s legacy has been the basic trope that permitted white Americans [to excuse] themselves from all racial guilt and project it to the American South.”

A group of historians – including Mr. Sokol and the University of Michigan’s Matt Lassiter – are revisiting how the North and South diverged after the Civil War. One of Mr. Lassiter’s findings is that Northern segregation happened largely by the same kind of government decrees that enshrined segregation in the South.

“The North has been a freer place, in some ways a better place [for blacks], but on the level of spatial segregation, structural inequalities, and poverty, [the North] is no better than the South and is, in many cases, worse,” says Sokol.

Sociologist James Loewen has also tackled this subject in Sundown Towns: A Hidden Dimension of American Racism. Loewen found that in the North between 1890 and 1940, blacks were forced out of many communities, often by informal “sundown laws” that required them to be out of a community by sundown or suffer the consequences.

An interesting article in a country that has difficulty discussing race and dealing with the consequences of a racialized society.
