    Noncommunicable diseases Account for a Growing Share of Total deaths, Especially in developing Regions. Noncommunicable diseases (NCDs), such as cardiovascular diseases, cancers, diabetes, and chronic lung diseases, are now the leading causes of death in all regions except sub-Saharan Africa. Four behavioral risk factors account for most NCDs: tobacco use, unhealthy diet, insufficient physical activity, and the harmful use of alcohol. In 2008, almost two-thirds of all deaths globally were from NCDs. And contrary to popular perception, nearly 4 out of 5 deaths from NCDs occurred in low- and middle-income countries. While the number of people suffering and dying from NCDs will continue to increase around the world over the next several decades, the greatest increases are expected in low-income countries. In sub-Saharan Africa, the region with the largest projected increase, almost half of all deaths will be from NCDs by 2030. In South Asia, deaths from NCDs are projected to increase from half to almost three-quarters of all deaths between 2008 and 2030.

    In Malawi, approximately 49 percent of the household population is under age 15. However, when the age structure of Malawi is examined by wealth quintile, the wealthy and the very poor have quite different age structures. Among the households in the wealthiest quintile, only 43 percent of the population is under age 15, reflecting a reduction in fertility in recent years (below 4 children per woman). When examining the age structure of the poorest quintile, approximately 53 percent of the household population is under age 15, reflecting both high levels of fertility (over 7 children per woman) and the need for investing large amounts in the health and education of this young population.

    Malawi Has a Youthful population, but its poor Are Much Younger and its wealthy Are Older.

    Noncommunicable diseases Result in More premature deaths in Low- and Middle- Income countries.

    SourceS: World Health Organization, Global Status Report on Noncommunicable Diseases 2010 (2011); and World Health Organization, Noncommunicable Diseases Country Profiles 2011 (2011).

    People living in low- and middle-income countries are more likely to die prematurely from NCDs than those in high-income countries: Almost 30 percent of all NCD deaths occur to people under age 60 in low and middle-income countries, compared to 13 percent in high-income countries. These general patterns are observed among both men and women. However, in most countries, a higher proportion of NCD deaths occur among men before age 60 than among women. Because people under age 60 are likely still in the labor force and may also be supporting family members, these premature deaths have important social and economic implications for individuals, families, and countries. Greater demands are placed on family resources to pay for medical care and meet caregiving needs, families lose financial support and risk impoverishment, and countries face reduced national productivity and slower economic growth.

    Between 2010 and 2011, the U.S. population increased by only 0.7 percent, a decline from the 1.0 percent growth rate that has been more typical in recent years. With the first baby boomers reaching retirement age in 2011, the U.S. population is also growing older. A decade ago, children under age 18 made up a significant component of annual population growth and exceeded the growth of the population ages 65 and older. But by 2011, these patterns had reversed. The number of people under age 18 declined by 190,000 between 2010 and 2011, while the number of older persons increased by 917,000. Growth in the number of working-age adults, including those in prime childbearing ages, is also down sharply. Because of its relatively young age structure, the United States still has a great deal of population momentum compared to many other developed countries. But as more baby boomers enter retirement and there are fewer people of reproductive age, we could see further declines in the number of births, and the age structure of the United States could start to resemble that of Europe.

    The U.S. population Is Growing More Slowly and Beginning to Age Rapidly.

    Nearly All Future population Growth will Be in the worlds Less developed countries.Developed countries as a whole will experience little or no population growth in this century, and much of that growth will be from immigration from less developed countries. The worlds poorest countries will see the growth. In 1950, 1.7 billion people lived in less developed countriesabout two-thirds of the world total; by 2050, the population of less developed countries will number over 8 billion, or 86 percent of world population. In 1950, only about 200 million of the population of the less developed countries resided in countries now defined as least developed by the United Nations, but that population is projected to rise to nearly 2 billion by 2050. Those countries have especially low incomes, high economic vulnerability, and poor human development indicators.

    AckNOwLEdGMENTS

    The authors gratefully acknowledge the valuable assistance of PRB staff members Donna Clifton and Amanda Roach; PRB interns Amy Chambliss, Carrie Fahey, Elaine Lydick, and Sarah Levy; staff of the International Programs Center of the U.S. Census Bureau; the United Nations (UN) Population Division; the Institut national detudes dmographiques (INED), Paris; and the World Bank in the preparation of this years World Population Data Sheet. This publication is funded by the William and Flora Hewlett Foundation, the David and Lucile Packard Foundation, the U.S. Agency for International Development ( IDEA Project, No. AID-0AA-A-10-00009), and supporters. The contents are the responsibility of the Population Reference Bureau and do not necessarily reflect the views of USAID or the United States government.

    NOTES

    The Data Sheet lists all geopolitical entities with populations of 150,000 or more and all members of the UN. These include sovereign states, dependencies, overseas departments, and some territories whose status or boundaries may be undetermined or in dispute. More developed regions, following the UN classification, comprise all of Europe and North America, plus Australia, Japan, and New Zealand. All other regions and countries are classified as less developed. The least developed countries consist of 48 countries with especially low incomes, high economic vulnerability, and poor human development indicators; 33 of these countries are in sub-Saharan Africa, 14 in Asia, and one in the Caribbean. The criteria and list of countries, as defined by the United Nations, can be found at www.unohrlls.org/en/ldc/.

    Sub-Saharan Africa: All countries of Africa except the northern African countries of Algeria, Egypt, Libya, Morocco, Tunisia, and Western Sahara.

    World and Regional Totals: Regional population totals are independently rounded and include small countries or areas not shown. Regional and world rates and percentages are weighted averages of countries for which data are available; regional averages are shown when data or estimates are available for at least three-quarters of the regions population.

    World Population Data Sheets from different years should not be used as a time series. Fluctuations in values from year to year often reflect revisions based on new data or estimates rather than actual changes in levels. Additional information on likely trends and consistent time series can be obtained from PRB, and are also available from UN and U.S. Census Bureau publications and websites.

    SOURcES

    The rates and figures are primarily compiled from the following sources: official country statistical yearbooks, bulletins, and websites; the United Nations Demographic Yearbook, 2009-2010 and Population and Vital Statistics Report of the UN Statistics Division; World Population Prospects: The 2010 Revision of the UN Population Division; and the International Data Base of the International Programs Center, U.S. Census Bureau. Other sources include recent demographic surveys such as the Demographic and Health Surveys, Reproductive Health Surveys, special studies, and direct communication with demographers and statistical bureaus in the United States and abroad. Specific data sources may be obtained by contacting the authors of the 2012 World Population Data Sheet. For countries with complete registration of births and deaths, rates are those most recently reported. For more developed countries, nearly all vital rates refer to 2011 or 2010.

    dEFINITIONS

    Mid-2012 PopulationEstimates are based on a recent census, official national data, or PRB, UN, and U.S. Census Bureau projections. The effects of refugee movements, large numbers of foreign workers, and population shifts due to contemporary political events are taken into account to the extent possible.

    Birth and Death RateThe annual number of births and deaths per 1,000 total population. These rates are often referred to as crude rates since they do not take a populations age structure into account. Thus, crude death rates in more developed countries with a relatively large proportion of high-mortality older population are often higher than those in less developed countries with lower life expectancy.

    Rate of Natural Increase (RNI)The birth rate minus the death rate, implying the annual rate of population growth without regard for migration. Expressed as a percentage.

    Net MigrationThe estimated rate of net immigration (immigration minus emigration) per 1,000 population for a recent year based upon the official national rate or derived as a residual from estimated birth, death, and population growth rates. Migration rates can vary substantially from year to year for any particular country, as can the definition of an immigrant.

    2050 Population as a Multiple of 2010Projected populations based upon reasonable assumptions on the future course of fertility, mortality, and migration. Projections are based upon official country projections, series issued by the UN or the U.S. Census Bureau, or PRB projections.

    Infant Mortality RateThe annual number of deaths of infants under age 1 per 1,000 live births. Rates shown with decimals indicate national statistics reported as completely registered, while those without are estimates from the sources cited above. Rates shown in italics are based upon fewer than 50 annual infant deaths and, as a result, are subject to considerable yearly variability; rates shown for such countries are averages for a multiple-year period.

    Total Fertility Rate (TFR)The average number of children a woman would have assuming that current age-specific birth rates remain constant throughout her childbearing years (usually considered to be ages 15 to 49).

    Population Under age 15/age 65+The percentage of the total population in these ages, which are often considered the dependent ages.

    life expectancy at BirthThe average number of years a newborn infant can expect to live under current mortality levels.

    Percent UrbanPercentage of the total population living in areas termed urban by that country or by the UN. Countries define urban in many different ways, from population centers of 100 or more dwellings to only the population living in national and provincial capitals.

    Prevalence of HIV/aIDsThe estimated percentage of adults, by sex, ages 15-49, living with HIV/AIDS. Figures are from UNAIDS 2010 Report on the Global AIDS Epidemic with updates from recent Demographic and Health Surveys. Some regional averages were calculated by PRB.

    Contraceptive UseThe percentage of currently married or in union women of reproductive age who are currently using any form of contraception. Modern methods include clinic and supply methods such as the pill, IUD, condom, and sterilization. Data are from the most recently available national-level surveys, such as Demographic and Health Surveys, Reproductive Health Surveys, Multiple Indicator Cluster Surveys, regional survey programs, national surveys, and the UN Population Division World Contraceptive Use 2011. For more developed countries, data refer to some point in the 1990s and early 2000s. Data for less developed countries are primarily from a point in the mid-2000s. Data prior to 2006 are shown in italics.

    GNI PPP per Capita, 2010 (Us$)GNI PPP per capita is gross national income in purchasing power parity (PPP) divided by mid-year population. GNI PPP refers to gross national income converted to international dollars using a purchasing power parity conversion factor. International dollars indicate the amount of goods and services one could buy in the United States with a given amount of money. Data are from the World Bank. Figures in italics are for 2009.

    age-standardized Death Rate for all Noncommunicable Diseases (NCDs) The numbers of deaths due to noncommunicable diseases per 100,000 population estimated for 2008 by sex and adjusted for differences in population age distribution across countries. Estimates for many developing countries and some developed countries are less reliable since they are not based on national NCD mortality data. Data are from Noncommunicable Diseases Country Profiles 2011 by the World Health Organization (WHO). Regional averages were calculated by PRB.

    Percent of all Deaths Due to NCDsThe estimated percentage of all deaths that occurred in 2008 that resulted from NCDs. Data are from WHOs Noncommunicable Diseases Country Profiles 2011. Regional averages were calculated by PRB.

    Prevalence of Underweight among Children Under age 5 The percentage of children ages 0-59 months who are moderately and severely underweight (below minus two standard deviations from median weight-for-age of the WHO Child Growth Standards). Data are from UNICEFs State of the Worlds Children 2012. Some regional averages were calculated by PRB.

    If you value PRBs World Population Data Sheet and are among the tens of thousands of people who eagerly anticipate its publication each year, please consider making a contribution to PRB. Your donation will help ensure that PRB can maintain its commitment to keeping the Data Sheet as affordable as possible. Visit our website to donate now: www.prb.org.

    INFORMPRB informs people around the world about issues related to population, health, and the environment. To do this, we transform technical data and research into accurate, easy-to-understand information.

    innovativE tools. DataFinder is a searchable database of hundreds of indicators for thousands of places.

    inFluEntial PuBliCations. PRBs Population and Economic Development 2012 Data Sheet, with 21 indicators from 140 low- and middle-income countries, presents a complex picture of countries still struggling with economic challenges and inequalities, while others are making significant headway.

    multimEDia. PRB has nearly 100 videos with leading experts on topics as wide-ranging as climate change, immigration, HIV/AIDS, and female genital mutilation. Many videos include PowerPoint presentations shown during seminars and press briefings. ENGAGE presentations feature the Trendalyzer software created by Hans Rosling.

    onlinE rEsourCEs. PRBs website offers full text of all PRB publications, including our respected Population Bulletins, and data and analysis on world issues ranging from gender to aging to family planning.

    EMPOWERPRB empowers peopleresearchers, journalists, policymakers, and educatorsto use information about population, health, and the environment to encourage action. Frequently, people have information but lack the tools needed to communicate effectively to decisionmakers. PRB builds coalitions and conducts trainings to share techniques to inform policy.

    Journalist nEtWorks. PRB builds the capacity of journalists from developing countries through seminars and study tours. We organized several study tours for journalists in Uganda, Kenya, Tanzania, Indonesia, and Mali to visit projects and the people they affect.

    PoliCy CommuniCation traininG. In the past decade, PRB has trained more than 800 professionals in Asia, Africa, and Latin America. Each year, we sponsored two workshops with Kenyas National Council for Population and Development, training local and regional policymakers, program managers, and advocates.

    Data WorksHoPs. PRBs data workshops and online training assist the Annie E. Casey Foundations KIDS COUNT network in using vital data about the status of children in the United States. Participants take away the knowledge needed to access data about their particular state and communicate with policymakers.

    ADVANCEPRB works to advance the well-being of current and future generations. Toward that end, we analyze data and research, disseminate information, and empower people to use that information to inform policymaking. While the numbers of publications created or workshops conducted are one way to measure PRBs work, the creation of evidence-based policies, increased demand for health services, and active coalitions are better gauges of progress toward positive social change.

    EviDEnCE-BasED PoliCiEs. PRB provides analysis for the KIDS COUNT Data Book, an annual report card on the well-being of children and families in the United States. The Data Book has helped promote the passage of several U.S. policies, including the State Childrens Health Insurance Program.

    DEmanD For HEaltH sErviCEs. Articles written as part of a media training effort in child marriage in Senegal led to the Vice President of the National Assemblys call for a study to understand and address this common and harmful practice.

    aCtivE Coalitions. PRB works with the East Africa Population, Health, and Environment Network to increase information sharing across the region. The AFRICAPHE online discussion group improves access to information and capacity-building and funding opportunities.
