Not so long ago, the city was seventh on the list, but it has now dropped to the ninth biggest U.S. city.
San Diego dropped one spot this year, to ninth place, as Dallas took over the No. 8 spot, the report shows.
The population of San Diego has dwindled to 1,279,329 as of July 2008. Dallas isn’t too far ahead, however, beating out our beachy borough by fewer than 600 people.
For decades, San Diego's story was about growth. In 1970, the city was listed at 14th, growing in 10 years to the eighth largest U.S. city.
Though it seems as if we are on a steady decline, the city's population grew last year by 1.5 percent -- faster than Dallas’ 1.1 percent. This gives us hope that we will one day retake that other Southwestern city.
