Houston, like Brooklyn and Boston, is a mixed bag: wealthy enclaves, immigrant communities rich and poor, students, government workers — your usual big urban confluence. In Harris County, the median household income is $50,577. In Brooklyn, it is $42,932, and in Suffolk County (which includes Boston and some nearby communities) it was $53,751. So, Boston has a median household income about 6 percent higher than Houston’s, while Brooklyn’s is about 15 percent lower than Houston’s.Brooklyn is not the poorest part of New York, by a long shot (the Bronx is), and, looking at those income numbers above, you may think of something Professor Krugman mentions but does not really take properly into account: New York and Boston have a significantly higher cost of living than does Houston, or the rest of Texas. Even though Houston has a higher median income than does Brooklyn, and nearly equals that of Boston, comparing money wages does not tell us anything like the whole story: $50,000 a year in Houston is a very different thing from $50,000 a year in Boston or Brooklyn.
