This WSJ infographic has been making the rounds, which shows an example of a single parent with two children and an income of $260k portrayed looking sad, presumably about their taxes going up by 5%.  It's been asked: How many "Single parent, two children" households are there with an income of $260,000 or more?

I believe I was able to determine an answer from the 2011 American Community Survey microdata.  First limiting to households composed exclusively of children and a single parent (as depicted), gets you down to 6.5 million households.    (Sanity check: Wikipedia cites about 13 million single-parent households, but that includes those with other adults present, and the microdata shows an equal number of single-parent households with a single adult and multiple adults.)

Further restricting to single parent with 2 children, exactly, gets you down to 2.1 million households.

Limiting to those with an income of $260,000 or more, leaves you with 9,489 households total, or the top 0.4% of single-parent two-children household incomes.  Median income for this demographic is $23,400.  90th percentile is $70k, and 95th percentile is $94k.
