Of course when it comes to growth and decline patterns, it seems like Houston sets its own path and doesn't always follow other cities precedents. I think a lot of Houston's "first ring" suburbs have already "cycled" through their decline and have bounced back, with the decline and stagnation then moving to what I guess you would call a second or third suburban ring. Inner-loop Southwest on thru Meyerland is extremely strong, pushing any ring of decline arguably out as far as Fondren and beyond. Northwest is similiar. Garden Oaks, Oak Forest, Spring Branch all saw declines in the past, and while parts of Oak Forest and Spring Branch can look a little sketchy, they are rebounding nicely, or already have rebounded, pushing the ring of decline out to starting more at Inwood & stretching to parts of FM 1960.
