ESCAPING POVERTY THROUGH WORK: THE PROBLEM OF LOW EARNINGS CAPACITY IN THE UNITED STATES, 1973–88

This paper documents the changes in earnings capacity poverty that occurred between 1973 and 1088. Families are "Earnings Capacity Poor" if they are unable to generate enough income to lift them out of poverty, even if all working-age adults in the family work full-time, year-round. Data from the March 1974 and March 1989 Current Population Surveys indicate that earnings capacity poverty increased more rapidly than official poverty. Much of this increase can be attributed to the rise in earnings capacity poverty among whites, intact families, and family heads with more than a high school diploma. Most alarming, the percentage of children in earnings capacity poor families is considerably higher than it is among persons over eighteen; in 1988, nearly 15 percent of children under six lived in families that could not have escaped poverty even if the adults in their family were working and earning at their full capacity levels.     

THE LOSS OF EARNINGS CAPABILITY FROM DISABILITY/HEALTH LIMITATIONS: TOWARD A NEW SOCIAL INDICATOR

Health problems and physical and mental impairments can restrict the kind and amount of work that individuals can perform. Several studies have estimated the loss in earnings experienced by disabled/health-limited workers, but they do not examine the trend in this loss over time. The authors propose an alternative indicator of productivity loss that is more appropriate for inter temporal comparisons: "lost earnings capability"–the difference between the amount of money persons could potentially earn if they were free of disability/health limitations and the amount of money that they can actually earn given their limitations. The estimates indicate that the mean lost earnings capability per disabled/health-limited person grew over the period from 1973 to 1988, while the population with disabilities/health limitations fell. In 1973, lost earnings capacity totaled about 5.3 percent of Gross National Product (GNP); by 1988, the loss had fallen to about 4.5 percent of GNP as a consequence of the reduction in the number of people with limitations. Data are from the Current Population Surveys and the Survey of Income and Program Participation.
