How much do your neighbors earn? You don't need to guess. Last week the IRS reported data compiled from income-tax filings submitted in 2009 and tabulated by individual ZIP code. Among the results for Southwestern Pennsylvania: The highest incomes can be found not in Upper St. Clair or Sewickley, but in Collier Township.
ZIP code 15142 -- which is part of Collier and home to the Nevillewood golf course and residential development -- had the single highest income in the region … and indeed the highest average income for any ZIP Code in Pennsylvania. The average return filed in 15142 reported an average income of $244,131; 24 percent of all filings reported an average adjusted gross income of at least $200,000 a year. That, too, was the highest proportion in the state.
More established affluent ZIP codes trailed behind: Average income in 15238 (Fox Chapel) came in at only $178,420; Sewickley's 15143 posted an average income of $156,431.
On the other end of the scale, the Monongahela Valley appears heavily in lower-income brackets. The lowest average income in Southwestern Pennsylvania -- $24,700 per return -- was reported for ZIP code 15110 (Duquesne). That was followed closely by $24,877 in 15104 (Braddock, North Braddock and Rankin). Rounding out the five lowest incomes were 15148 (Wilmerding), 15351 (Nemacolin, in Greene County, which is not the address of the resort bearing the same name) and 15435 (Fairbank, in Fayette County).
The data here comes from the U.S. Internal Revenue Service's Statistics of Income (SOI) program, which uses the Federal tax system as a comprehensive source of economic and financial information. Income data reflects the Adjusted Gross Income (AGI) reported on individual tax filings; it does not include revenue from capital gains. The IRS reports aggregate data on income and the number of returns by ZIP code. Extracted here are data for ZIP codes in Southwestern Pennsylvania -- those beginning in 150, 151, 152, 153, 154, 156 and 160. The IRS did not report data for ZIP Codes with fewer than 250 filings. The data comes from tax returns filed between Jan. 1, 2009 and Dec. 31, 2009. Such returns generally reflect data for income in 2008.
