Income Data for ZIP Code Areas, 1966

This data collection contains aggregate information from income tax returns for 5-digit ZIP-code areas for the entire United States. Data are provided for three income classes with adjusted gross income returns of under $3,000, $3,000 to $10,000, and over $10,000. Information is provided on gross income, taxes paid, personal exemptions, total number of joint returns filed by married couples, and aggregate number of returns filed by all taxpayers. These data, originally prepared by the Internal Revenue Service, were supplied to ICPSR in computer-readable form by Philip Lankford of the University of California at Los Angeles.
