Who is poor inAmerica This is a hard question to answer.Despite poverty’s messiness, we’ve measured progress against it by a single statistic: the federal poverty line. In 2008, the poverty threshold was $ 21,834 for a four-member family with two children under 18.By 1his measure, we haven’t made much progress.Except for recessions, when the poverty rate can rise to 15 percent, it’s stayed in a narrow range for decades. In 2007—the peak of the last business cycle—the poverty rate was 12.5 percent; one out of eightAmericans was "poor. " In 1969, another business-cycle peak, the poverty rate was 12.1 percent.But the apparent lack of progress is misleading for two reasons.

First, it ignores immigration. Many immigrants are poor and low skilleD、They add to the poor. From 1989 to 2007, about three quarters of the increase in the poverty population occurred among Hispanics—mostly immigrants, their children, and grandchildren. The poverty rate for blacks fell during this period, though it was still much too high (24.5 percent in 2007). Poverty "experts" don’t dwell on immigration, because it implies that more restrictive policies might reduce U.S. poverty.
Second, the poor’s material well-being has improveD、The official poverty measure obscures this by counting only pretax cash income and ignoring other sources of support. These include the earned-income tax credit (a rebate to low-income workers), food stamps, health insurance (Medicaid), and housing subsidies.Although many poor live hand to mouth, they’ve participated in rising living standards. In 2005, 91 percent had microwaves, 79 percent air-conditioning, and 48 percent cell phones.
The existing poverty line could be improved by adding some income sources and subtracting some expenses (example: child care). Unfortunately, the administration’s proposal for a "supplemental poverty measure" in 2011—to complement, not replace, the existing poverty line—goes beyond that. The new poverty number would compound public confusion. It also raises questions about whether the statistic is tailored to favor a political agend
A、
The "supplemental measure" ties the poverty threshold to what the poorest third ofAmericans spend on food, housing, clothing, and utilities. The actual threshold not yet calculated—will probably be higher than today’s poverty line. Moreover, this definition has strange consequences. Suppose that allAmericans doubled their income tomorrow, and suppose that their spending on food, clothing, housing, and utilities also doubleD、That would seem to signify less poverty—but not by the new poverty measure. It wouldn’t decline, because the poverty threshold would go up as spending went up. ManyAmericans would find this weirD、, people get richer, but "poverty" stays stuck.
What produces this outcome is a different view of poverty. The present concept is an absolute one: the poverty threshold reflects the amount estimated to meet basic needs.By contrast, the new measure embraces a relative notion of poverty: people are automatically poor if they’re a given distance from the top, even if their incomes are increasing.
Poverty experts are reluctant to talk about immigration because
[A] they may be immigrants or children of immigrants.
[B] they don’t admit that blacks have improved their life.
[C] poverty has been reduced through restrictive policies.
[D] they may be taken as opponents to free immigration policies.
