| This paper presents a profile of poverty in Egypt for 1997. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic groups, provides information on the characteristics of the poor, illustrates the heterogeneity among the poor, and helps identify empirical correlates of poverty. The poverty profile is constructed using data from the recently completed Egypt Integrated Household Survey, a nationwide, multiple-topic household survey, carried out by the International Food Policy Research Institute in coordination with the Ministry of Agriculture and Land Reclamation and the Ministry of Trade and Supply. Reference poverty lines that take into account regional differences in food and nonfood prices, age and composition of... |

| Poverty profiles are a useful way of summarizing information on the levels of poverty and the characteristics of the poor in a society. They also provide us with important clues to the underlying determinants of poverty. However, important as they are, poverty profiles are limited by the bivariate nature of their informational content. The bivariate associations typical in a poverty profile can sometimes be misleading; they beg the obvious question of the effect of a particular variable conditional on the other potential determinants. While there may be certain contexts where unconditional poverty profiles are relevant to a policy decision (see Ravallion 1996), often one would be interested in the "conditional" poverty effects of proposed policy... |

| Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample. The sample for the U.S. Current Population Survey (CPS), which serves as the basis for official poverty, unemployment, and earnings estimates, results from a stratified and clustered design. Unfortunately, analysts are frequently unable to estimate sampling variance for many CPS statistics because the variables marking the strata and clusters are censored from the public-use data files. To compensate for this, the Bureau of Census provides a method to approximate the sampling variance for several, specific point estimates, but no... |

| This paper considers alternate measures of overweight in the U.S. that are sensitive to changes in the body-mass index (BMI) distribution, more robust to measurement error and continuous in the body-mass index (BMI) at the overweight threshold. The measures suggest that standard prevalence rates may be understating the severity of the problem. Since 1971, overweight prevalence has increased by 40% while the distribution-sensitive measure has increased by 174%. They also provide some useful insight into socioeconomic differences in overweight. For example, overweight prevalence rates for the poor and the rich have been very similar over the last 30 years, with the rich have a slightly higher rate in the most recent 2001- 2002 data. In contrast, the... |

| Both public and private organizations have noted that Americans generally eat less fruits and vegetables than is recommended in the Food Guide Pyramid. For example, the Produce for Better Health Foundation found that only 38 percent of Americans consume the recommended number of servings of vegetables, while only 23 percent consume the recommended number of servings of fruit. Even more troubling, low-income households eat even less fruits and vegetables than higher income households. |

| In 2000, 8.8 million children received food stamps, making the Food Stamp Program a crucial component of the social safety net. Despite its importance, little research has examined the effect of food stamps on children's overall well-being. Using the Current Population Survey from 1989 to 2001, we consider the impact of food stamps on three measures of poverty - the headcount, the poverty gap, and the squared poverty gap. These measures portray the incidence, depth, and severity of poverty. We find that in comparison to the headcount measure, food stamp benefits lead to large reductions in the poverty gap and squared poverty gap measures. We then simulate the effects of several changes in the distribution of food stamps and find that a general... |

| This report analyzes fruit and vegetable expenditures by low-income households and higher income households, and compares the sensitivity of both groups' purchases to changes in income. On average, low-income households spent $3.59 per capita per week on fruits and vegetables in 2000 while higher income households spent $5.02-a statistically significant difference. In addition, a statistical demand model indicates that marginal increases in income received by low-income households are not spent on additional fruits and vegetables. In contrast, increases in income received by higher income households do increase their fruit and vegetable expenditures. One interpretation of this finding is that low-income households will allocate an additional dollar of... |

| This paper aims to answer how best to model education attainment, which is an individual-level variable, in household-level income functions. The accepted practice in the literature is to use the education level of the household head. This paper compares the head-of-household model to three competing models and concludes that the maximum or average level of education in the household is a better explanatory variable of household income. Least absolute deviations (LAD) estimators and censored least absolute deviations (CLAD) estimators are used to predict income. Standard errors, which are robust to violations of homoscedasticity and independence, are generated by a boot-strap method that replicates the two-stage sample design. |
