S. Bureau of the Census, Current Population Reports, Series P70-73, 2001. Data are from the Survey of Income and Program Participation for 1997. 2 percent. 7 percent. 13 What characterizes the demographic composition of the poor? 14 • Blacks make up one-quarter of the poor population, with Hispanics making up an additional quarter. • More than one-third of the poor are children, and nearly two-thirds of the poor are below age 35. • Women make up three->fths of the poverty population over the age of eighteen.
