About the Report

Released October 2003

This report is one of a series of Country Health Statistical Reports produced on behalf of the United States Agency for International 

Development (USAID) by the Population, Health and Nutrition Information (PHNI) Project. Each profile contains statistical data on 

current health conditions, population dynamics, health and family planning behavior, and health and population trends in a given

developing country. Information is compiled from PHNI's health statistics database, which draws data from a diverse range of sources 

listed at the end of this profile.

Hard copy editions of USAID's profiles are available from PHNI'S publications department. Reports are available on the USAID Global 

Health Web site in Portable Document Format (pdf). Any feedback you have on the content or presentation of this report would be

Data Notes

 *Indicator definitions that differ from those in the data notes section are identified by footnotes accompanying the indicator tables.

Demographic Indicators

Total Population The number of people in a given area (i.e., country) in a particular time period (usually a midyear 

estimate). 

Population Growth Rate The average annual growth rate is the rate of natural increase in a population plus the net migration rate. 

The rate of natural increase is the difference between the birth rate and the death rate, but it is 

conventionally measured in percentage terms (per hundred rather than per thousand). 

Percent Urban The percentage of the midyear population living in areas defined as urban in each country and reported 

to the United Nations. 

Women, 15-19 The number of women between the ages of 15-19 in the midyear population. 

Women, 15-49 The number of women between the ages of 15-49 in the midyear population. 

Life Expectancy at Birth The average number of years that a person at age 0 will live if age-specific death rates remain constant. 

Life expectancy at birth is highly affected by rates of infant and child death. 

Crude Birth Rate The number of births per thousand of the population. The product of the number of live births, divided by 

the midpoint population, multiplied by 1,000. 

Crude Death Rate The number of deaths per thousand of the population. The product of the number of deaths divided by 

the midpoint population, multiplied by 1,000. 

Number of Live Births The number of live births, annually, within a country. 

Socioeconomic Indicators

GNI per Capita (PPP) The gross national income (GNI) converted to international dollars using purchasing power parity (PPP) 

rates. An international dollar has the same purchasing power over GNI as a U.S. dollar has in the United 

States. 

Health Expenditure as 

Percentage of GDP 

Total health expenditures is the sum of public and private health expenditures figured as a percentage of 

a country's gross domestic product (GDP). It covers the provision of health services (preventive and 

curative), family planning activities, nutrition activities, and emergency aid designated for health but does 

not include provision of water and sanitation. 

Physicians per 1,000 

People 

Physicians are defined as graduates of any faculty or school of medicine who are working in the country 

in any medical field (practice, teaching, research). 

Adult Literacy Rate The percentage of people ages 15 and over who can, with understanding, read and write a short, simple 

statement about their everyday life. 

Adult Literacy Rate, 

Female 

The percentage of women ages 15 and over who can, with understanding, read and write a short, simple 

statement about their everyday life. 

Adult Literacy Rate, Male The percentage of men ages 15 and over who can, with understanding, read and write a short, simple 

statement about their everyday life. 

Gross Enrollment Rate - 

Primary School 

Total enrolment in primary level of education, regardless of age, expressed as a percentage of the 

official school-age population corresponding to primary level of education in give school-year. GER can 

be over 100% due to the inclusion of over-aged and under-aged pupils/students because of early or late 

entrants, and grade repetition. 

Gender Parity Index - Net 

Enrollment Rate 

The ratio of the female-to-male net primary school enrollment rates measures progress towards gender 

equity in school attendance and the level of learning opportunities available for women in relation to 

those available to men. Calculation Method: Divide the female net primary school enrollment rate by the 

male net primary school enrollment rate. 
Access to an Improved 

Water Source (Rural) 

Access to an improved water source in rural areas. Refers to the percentage of the rural population with 

reasonable access to an adequate amount of water from an improved source, such as a household 

connection, public standpipe, borehole, protected well or spring, or rainwater collection. Unimproved 

sources include vendors, tanker trucks, and unprotected wells and springs. Reasonable access is 

defined as the availability of at least 20 liters a person a day from a source within one kilometer of the 

dwelling. 

Access to an Improved 

Water Source (Urban) 

Access to an improved water source in urban areas. Refers to the percentage of the urban population 

with reasonable access to an adequate amount of water from an improved source, such as a household 

connection, public standpipe, borehole, protected well or spring, or rainwater collection. Unimproved 

sources include vendors, tanker trucks, and unprotected wells and springs. Reasonable access is 

defined as the availability of at least 20 liters a person a day from a source within one kilometer of the 

dwelling.

effectively prevent human, animal, and insect contact with excreta. 

Access to Improved 

Sanitation Facilities 

(Urban)
