Characteristics of Low-Income CountriesLow incomes are often associated with other characteristics: severe inequality, poor health care and education, high unemployment, heavy reliance on agriculture, and rapid population growth. We will examine most of these problems in this section. Population growth in low-income nations is examined later in the chapter. InequalityNot only are incomes in low-income countries quite low; income distribution is often highly unequal. Poverty is far more prevalent than per capita numbers suggest, as illustrated by Lorenz curves, introduced in the chapter on inequality, that show the cumulative shares of income received by individuals or groups. Consider Costa Rica and Panama, two Latin American countries with roughly equivalent levels of per capita GNI (Costa Rica’s was $5,560 and Panama’s $5,510 in 2007). Panama’s income distribution is comparatively less equal, while Costa Rica’s is far more equal. Figure 19.1 "Poverty and the Distribution of Income: Costa Rica versus Panama" compares the 2003 Lorenz curves for Costa Rica and Panama, the most recent year for which the information was available. The 20% of the households with the lowest incomes in Costa Rica had twice as large a share of their country’s total income as did the bottom 20% of households in Panama. That means Costa Rica’s poor were about twice as well off, in material terms, as Panama’s poor. Figure 19.1 Poverty and the Distribution of Income: Costa Rica versus Panama 
Costa Rica had about the same per capita GNI as Panama in 2003, but Panama’s income distribution was far more unequal. Panama’s poor had much lower living standards than Costa Rica’s poor, as suggested by the Lorenz curves for the two nations. Source: World Development Indicators Online (revised October 17, 2008). In general, the greater the degree of inequality, the more desperate is the condition of people at the bottom of an income distribution. Given the high degree of inequality in many low-income countries, it is very important to look at income distributions when we compare living standards in different countries. Health and EducationPoor nations are typically characterized by low levels of human capital. Where health-care facilities are inadequate, that human capital can be reduced further by disease. Where educational resources are poor, there will be little progress in improving human capital. One indicator of poor health care appears on the supply side. Low-income countries have fewer doctors, relative to their populations, than high-income countries. For example, the UN estimates that in 2006 about 60% of mothers giving birth in developing countries had access to a skilled health-care provider (doctor, nurse, or midwife). While that is up from 47% in 1990, the lack of access to a health-care provider may explain much of the difference in maternal death rates between developed and developing countries: about nine maternal deaths per 100,000 live births in developed countries compared to about 450 per 100,000 in developing countries. [3] We can also see the results of poor health care in statistics on health. Among the world’s developing countries, the infant mortality rate, which reports deaths in the first year of life, was 57 per 1,000 live births in 2005. There were six infant deaths per 1,000 live births among the high-income countries that year. [4] Another health issue facing the world’s low-income countries is malnutrition. Malnutrition rates in all developing countries in the 2002 to 2004 period averaged 17%, 35% in the least developed countries. Still another issue is the spread of HIV/AIDS. Here there is some progress. The number of people newly infected declined from 3 million in 2001 to 2.7 million in 2005. Antiretroviral treatments are also leading to a reduction in deaths from 2.2 million in 2005 to 2 million in 2007. Longer survival means that the number of people living with HIV (from just under 30 million in 2001 to about 33 million in 2007) is rising and most of the people living with HIV are in Sub-Saharan Africa. [5] Education in poor and middle-income nations is improving. In 1991, about 80% of children in developing countries were enrolled in primary schools. In 2005, about 85% were. The comparable numbers in developed countries are about 95%. Enrollment rates taper off for high school (about 53% in 2005 in developing countries compared to 91% in developed countries). [6] UnemploymentUnemployment is pervasive in low-income nations. These nations, already faced with low levels of potential output, are producing well below their potential. Unemployment rates in low-income countries vary widely, reaching as high as 15% or more in some countries. If we count discouraged workers, people who have given up looking for work but who would take it if it were available, and people who work less than full time, not by choice but because more work is unavailable, then unemployment in low-income countries soars—often to more than 30%. Migration within low-income countries often contributes to unemployment in urban areas. Factors such as ethnic violence, poverty, and drought often force people to move from rural areas to cities, where unemployment rates are already high. Reliance on AgricultureOne of the dominant characteristics of poor nations is the concentration of employment in agriculture. Another is the very low productivity of that employment. Agriculture in low-income countries often employs a majority of the population but produces less than one-third of GDP. One of the primary forces behind income growth in wealthy countries has been the shift of labor out of agriculture and into more productive sectors such as manufacturing. This shift is also occurring in low-income nations but has lagged far behind. The solution to these problems lies in economic development, to which we turn next.
