DEFINITIONS

Personal income is the income received by all persons from participation in production, from government and business transfer payments, and from government interest. Personal income is the sum of net earnings by place of residence, rental income of persons, personal dividend income, personal interest income, and transfer payments. Net earnings are earnings by place of work—the sum of wage and salary disbursements (payrolls), other labor income, and proprietors' income—less personal contributions for social insurance, plus an adjustment to convert earnings by place of work to a place- of-residence basis. Personal income is measured before the deduction of personal income taxes and other personal taxes and is reported in current dollars (no adjustment is made for price changes).

The estimate of personal income in the United States is derived as the sum of the county estimates; it differs from the estimate of personal income in the national income and product accounts (NIPA's) because of differences in coverage and in the timing of the availability of source data.

As part of personal income, BEA prepares estimates of wage and salary disbursements by State and county. The Census Bureau and the Bureau of Labor Statistics (BLS) also prepare county-level estimates of wages and salaries.

The Census Bureau's County Business Patterns (CBP) employment and payroll data are an annual extension of the quinquennial economic censuses; the data are derived from surveys of business establishments and from Federal administrative records of the Internal Revenue Service, the Social Security Administration, and BLS. The data exclude agricultural production employees, household employees, and most government employees, which are included in BEA's estimates of wage and salary disbursements.

The BLS county wage data are derived from the Covered Employment and Wages, or ES-202, program; the data are tabulations of monthly employment and quarterly total wages of workers who are covered by State unemployment insurance (UI) and of Federal workers who are covered by the unemployment compensation for Federal employees (UCFE) program. The BLS data include civilian government and some agricultural production employees and household employees.

The BLS data account for 95 percent of the wage and salary component of BEA's estimates of personal income. The remainder consists of adjustments that BEA makes to account for employment and wages not covered, or not fully covered, by the State UI and UCFE programs.

Per capita personal income (PCPI) is the annual total personal income of residents divided by resident population as of July 1. In March 2006, the Census Bureau released county intercensal population estimates for 2000-2005 that were consistent with the April 1, 2000 Census counts.
