TL;DR (in advance): I think you are correct in your estimate, though household income is higher than that. $100K household income is still considerably higher than most Americans make.
Just to give some real numbers, the median household income in the US is $63,688. Unfortunately I couldn't find reliable numbers for dual income families in the US, but it appears to be over 60% (I saw numbers anywhere between 60-69%, but unfortunately no authoritative references).
Rough histogram of income distribution is:
10th percentile: < $15K
20th percentile: $15K <=> $25K
30th percentile: $25K <=> $35K
40th percentile: $35K <=> $50K
50th percentile: $50K <=> $65K
60th percentile: $65K <=> $80K
70th percentile: $80K <=> $130K
80th percentile: $130K <=> $160K
90th percentile: > $160K
I constructed this from a variety of different sources since I couldn't find anything that stated it explicitly. It is not entirely accurate, but it should give you a rough idea of the distribution. Would be nice if someone could find better data.
