Worked full year, full time with employment income

The term 'Full-year full-time workers' refers to persons 15 years of age and over who worked 49 to 52 weeks (mostly full time) in the reference year for pay or in self-employment.

Earnings or employment income

Refers to total income received by persons 15 years of age and over during calendar year 2005 as wages and salaries, net income from a non-farm unincorporated business and/or professional practice, and/or net farm self-employment income.

Standard error of average income

Refers to the estimated standard error of average income for an income size distribution. If interpreted as shown below, it serves as a rough indicator of the precision of the corresponding estimate of average income. For about 68% of the samples which could be selected from the sample frame, the difference between the sample estimate of average income and the corresponding figure based on complete enumeration would be less than one standard error. For about 95% of the possible samples, the difference would be less than two standard errors and, in about 99% of the samples, the difference would be less than approximately two and one half standard errors.

Median income of individuals

The median income of a specified group of income recipients is that amount which divides their income size distribution, ranked by size of income, into two halves, i.e., the incomes of the first half of individuals are below the median, while those of the second half are above the median. Median income is calculated from the unrounded number of individuals (e.g., males 45 to 54 years of age) with income in that group.

Average income of individuals

Average income of individuals refers to the weighted mean total income of individuals 15 years of age and over who reported income for 2005. Average income is calculated from unrounded data by dividing the aggregate income of a specified group of individuals (e.g., males 45 to 54 years of age) by the number of individuals with income in that group.
