您引的数说的是收入，我说的是财产，而且年份也不一样。
why couldn't I find the numbers online? only found white vs. non-white
没钱抢也是先抢黑兄弟，再抢中产。富人区都是住Gated Community，进去有点困难。只要富人在，American Dream就在。
估计你是想问这个：这是户数(# of households，也可以粗略地译成家庭数)根据收入水平的分布(大概也可以叫百分比)。
数的百分比？比如：1.78%:收入>=25万是指收入达到或等于25万的应缴1.78%的税 ，还是说在缴税表上收入达到或等于25万的只占1.78%
"缴税表上收入达到或等于25万的只占[总户数的]1.78%"
记得另外一个相关的数是，按1976年物价算，收入超过20万(也可能是25万，记不真切了)的户数比例一直是在0.35%左右。按2009年的物价，就要达到60多万的收入－有几位在美国混饭的同学能站出来
帮助大家对号入座，这里的收入比一般的定义要广一点，大家不要坐错了屁股。
