Even in the best of times, Sacramento tends to be a prisoner to low self-esteem. The region's population and economic growth have been humming along nicely for the past decade, drawing ever more educated workers from overpriced coastal counties, but the region's leaders have often seemed defensive about their flourishing town.

So perhaps it's not surprising that the mortgage meltdown, which has hit the area hard, has sparked something of an identity crisis. Yet in trying to cope with hard times, it's important that the region not lose its focus on what paced Sacramento's past success: its ability to offer affordable, high-quality, largely single-family neighborhoods for middle class families.

Sadly, the dominant narrative among many planners, politicians and developers in Sacramento today is to try to shed the family-friendly image. There's a growing consensus that low-density neighborhoods are passé and that the region's future success lies in retrofitting the region along a high-density, centralized model. Suburban areas like Rancho Cordova or Elk Grove, some believe, are destined to become the "the next slums" as middle-income homeowners, fleeing high gas prices, flock to the urban core.

Although a healthier downtown with reasonable density is good for the entire region, the high-density focus does not make a good fit for a predominately middle class, family-oriented region such as Sacramento. Unlike an elite city like San Francisco, Sacramento's growth has been fueled by an influx of educated, family-oriented residents – the populations that have been fleeing such high-priced places where the housing supply is constrained.

Long-term demographic trends, and perhaps common sense, suggest that most people do not move to Sacramento to indulge in a "hip and cool" urban lifestyle. If someone craves the excitement, bright lights and glamorous industries of a dense city, River City pales compared with places like San Francisco, New York or Los Angeles.

The fact Sacramento has fared far better than these cities over the past 15 years suggests the region's recent problems lie not in a lack of downtown condos and nightlife, but with a housing market that, as in much of California, has been totally out of whack. Once a consistently affordable locale, by the mid-1990s Sacramento's housing prices jumped almost nine times income growth, an unsustainable pace seen in a few areas such as Riverside, Miami and Los Angeles.

As a result, the refugees from the coastal counties who had been coming to Sacramento for affordable housing stopped arriving. Net migration to the region, more than 36,000 in 2001, fell to less than 1,000 in 2006.

Ultimately only a housing market correction will again lure the people who have come to Sacramento seeking single-family houses – the type of home favored by about 80 percent of Californians – back to the region. Evidence that these people, or current suburbanites, might flock back to the core city is thin at best. The failures of such high-profile projects as The Towers and the region's stagnant rental market do not suggest a seismic shift toward denser living.

One key reason has to do with patterns of job growth. Since 2000, suburban communities in the largest metropolitan areas have added jobs at roughly six times the rate of the urban cores.

This pattern has had profound and often counterintuitive effects on commuting distances. Planners and journalists tend to think of cities in traditional concentric rings, with distance from the core as the key measurement of distance from jobs. But in most regions, the vast majority of employment is outside the core. Even in Sacramento, a state capital, only about 1 in 10 jobs are in the city center. Exurban employment growth since 2000 has been the fastest regionally, expanding at nearly twice the rate for Sacramento County.

This means commuting distance – and thus exposure to higher gas prices – reflects more than proximity to the central core. In such diverse regions as Los Angeles and Chicago, the shortest average commutes exist both in the affluent inner-city neighborhoods and those suburbs and exurbs, where much of the employment growth has clustered. People who live in Irvine or Ontario in Southern California, or in the western suburbs of Chicago, for example, actually have shorter commutes than those residing in the barrios around downtown Los Angeles or in the Windy City's fabled South Side.
