Trends in the Family Income Distribution by Race/Ethnicity and Income Source, 1988-2009.

POVERTY, INFANT MORTALITY, AND HOMICIDE RATES IN CROSS-NATIONAL PERPSECTIVE: ASSESSMENTS OF CRITERION AND CONSTRUCT VALIDITY.

This paper assesses the extent to which the infant mortality rate might be treated as a "proxy" for poverty in research on cross-national variation in homicide rates. We have assembled a pooled, cross-sectional time-series dataset for 16 advanced nations over the 1993-2000 period that includes standard measures of infant mortality and homicide and also contains information on two commonly used "income-based" poverty measures: a measure intended to reflect "absolute" deprivation and a measure intended to reflect "relative" deprivation. With these data, we are able to assess the criterion validity of the infant mortality rate with reference to the two income-based poverty measures.

Family Income at the Bottom and at the Top: Income Sources and Family Characteristics.

Attention has recently been focused on wealth as a source of long-term economic security and on wealth ownership as a crucial aspect of the racial economic divisions in the United States. This literature, however has been concerned primarily with the wealth gap between poor and middle-class families, and between the white and black middle class. In this paper, we investigate the incomes of families at the top and bottom of the family income distribution.
