I’ve been reading through the LA County Department of Public Health’s report (PDF) on Life Expectancy in Los Angeles county. It’s not only interesting because it measures the life expectancy of Santa Clarita residents (a flat 80.0 years), but it shows the leading causes of death in the County as a whole for men and women:
According to Wikipedia generic “heart disease” is the leading killer in the United States, accounting for 25.4% of all deaths in the US. So its rank as the number one killer of both men and women in LA County is hardly surprising.
But who would have thought homicide and motor vehicle crashes account for the #2 and #3 causes of premature death respectively for men in LA County? Do men get into that many crashes in LA County that it ranks as the #3 killer of us? Apparently so.
Sadly, homicide ranks as the #1 killer of blacks and Latinos in LA County, according to the report. Lung disease is the #2 killer of whites behind heart disease, followed by motor vehicle crashes. As the report notes, risky behavior contributes heavily to these causes of death.
Speaking of health and motor vehicles, there’s another aspect to the report that applies to us here locally. I don’t think Santa Clarita is more or less obese than any other community, but the report notes that obesity “is one of the greatest challenges facing Los Angeles County” and that, taken together with diabetes, “threatens to halt and even reverse the gains in life expectancy we’ve achieved.”
As many planners and so-called new-urbanists have argued for years, increased obesity rates are a direct result of suburban, car-friendly and pedestrian-unfriendly development (see this 2003 NYT story “As Suburbs Grow, So Do Waistlines” for a sample). And this report takes that same line, arguing that city planners and decision makers ought to “increase access to safe places for residents to walk, bike, play and exercise” and “incorporate health considerations in General Plans, transportation plans and redevelopment activities.”
And I think “incorporating health considerations” is one thing the City of Santa Clarita (and arguably Newhall Land with Newhall Ranch) is trying to accomplish with its “valley of villages,” ped-friendly concept. Of course one SCV man’s ped-friendly, jobs/housing balanced development is another man’s high density OVOV nightmare (that they moved here to escape from!) so therein lies the crux of the matter.
This is one of the reasons I choose to live in Newhall and one of the reasons I’d live in Valencia: they are relatively walkable compared to other areas of the SCV like Stevenson Ranch. And this report backs that idea up: living in walkable communities contributes to a healthy, more active lifestyle.
