Source: Various panels of the Survey of Income and Program Participation matched to the administrative earnings data from the Social Security Administration.
Note: The sample consists of households whose heads were between the ages of 25 and 55, inclusive. Income is inflated to 2006 dollars using the CPI-U-RS. The household head is the person (or one of the persons) in whose name the home is owned or rented. If the house is owned jointly by a married couple, either the husband or the wife may be listed first, thereby becoming the householder. The top and bottom 2 percent of households in the income distribution in either Year 1 or Year 2 are excluded from the sample.
↵a Year is the second year of a two year period.
