Southern California, one market at a time. 南加州，一个市场接一个市场地看。
Across — Southern California cities, the quarter that was cheapest to buy into grew fastest: median population — since —, against — for the most expensive quarter. 南加州 — 个城市里，最买得起的那四分之一增长最快：— 年以来人口中位 —，而最买不起的四分之一是 —。
Association, not cause. Inland cities are both cheaper and have land to build on, and that alone would produce the same pattern. Ranked correlation −0.37 against current affordability; −0.54 against 2010 price levels, which precede the growth they are compared with. 这是相关，不是因果。内陆城市既便宜、又有地可盖，光这一条就能产生同样的形态。与当前可负担的秩相关是 −0.37；与 2010 年房价（在增长之前）的秩相关是 −0.54。
Size = population · Ring = gaining (green) / losing (red) people · Color = affordability vs the regional median (greener = cheaper than most, redder = pricier) 大小 = 人口 · 圆环 = 人口在涨（绿）/ 在缩（红）· 颜色 = 相对全区中位的可负担度（越绿=比多数便宜，越红=更贵）
The numbers above compare cities with each other. Both paths below go inside a single market. 以上的数字是城市之间的比较。下面两条路是走进其中一个市场。
