Counting the World: UNFPA Highlights the Challenges of Census-Taking
›The United Nations biannual population projections are some of the most (if not the most) widely used numbers in demography. Researchers and policymakers alike rely on the figures to plan for present and future challenges. But few consider the story behind the statistics. Where does the data come from? The United Nations Population Fund (UNFPA) recently released a short documentary on conducting censuses in challenging environments, with a spotlight on Indonesia, Chad, the Palestinian Territories, Belarus, and Bolivia.

António Guterres, The New York Times
Why Mali Matters
›September 11, 2012 // By Wilson Center Staff
The original version of this op-ed, by António Guterres, appeared in The New York Times.
For many people, Timbuktu has long represented the essence of remoteness: a mythical, faraway place located on the boundaries of our collective consciousness. But like many of the myths associated with colonialism, the reality is very different.

Farzaneh Roudi for the Middle East Program
Iran Is Reversing Its Population Policy
›Excerpted below is the introduction by Farzaneh Roudi. The full report is available for download from the Wilson Center’s Middle East Program.
Once again, the Iranian government is reversing its population policy – its fertility policy, to be more precise. Alarmed by the country’s rapidly aging population, Iran’s Supreme Leader Ayatollah Ali Khamenei is now calling on women to procreate and have more children, and the Iranian Minister of Health and Medical Education Marzieh Vahid Dastjerdi has recently said, “The budget for the population control program has been fully eliminated and such a project no longer exists in the health ministry. The policy of population control does not exist as it did previously.”

Coming of Age: Reason for Optimism in Burma’s Turn Towards Democracy
›Burma (also known as Myanmar), a country plagued by internal political turmoil and direct or tacit military rule since 1962, had its first general elections in 50 years in 2010 and long-time jailed opposition leader Aung San Suu Kyi won a seat in the National Assembly, but questions remain as to how much power the military is willing to cede. Demography provides reason for hope that this turn towards democracy is more than temporary.

In Poor Countries, Is Lower Fertility Bad for Equality?
›August 23, 2012 // By Wilson Center StaffThe original version of this article appeared on The Economist.
Economies benefit when people start having smaller families. As fertility falls, the share of working-age adults in the population creeps up, laying the foundation for the so-called “demographic dividend.” With fewer children, parents invest more in each child’s education, increasing human capital. People tend to save more for their retirement, so more money is available for investment. And women take paid jobs, boosting the size of the workforce. All this is good for economic growth and household income. A recent National Bureau of Economic Research study estimated that a decrease of Nigeria’s fertility rate by one child per woman would boost GDP per head by 13 percent over 20 years. But not every consequence of lower fertility is peachy. A new study by researchers at the Harvard School of Public Health identifies another and surprising effect: higher inequality in the short term.

Hans Rosling on Religion, Babies, and Poverty
›“I’m going to talk about religion. But it’s a broad and very delicate subject, so I have to limit myself. Therefore I will limit myself to only talk about the links between religion and sexuality…I will talk on what I remember as the most wonderful – it’s the moment when the young couple whispers, ‘tonight, we are going to make a baby,’” said Hans Rosling, the eclectic Swedish doctor and statistician known for his Gapminder tool, in a TedxSummit presentation in April.

Population and Sustainability in an Unequal World
›August 13, 2012 // By Laurie MazurJune’s Rio + 20 Conference on Sustainable Development left environmentalists little to cheer about. Kumi Naidoo, executive director of Greenpeace International, called the meeting “a failure of epic proportions.” And Washington Post reporter Juliet Eilperin said the conference “may produce one lasting legacy: convincing people it’s not worth holding global summits.”

PRB’s 2012 World Population Data Sheet
›“The most rapid population growth in many ways [occurs in] the countries that can least afford it,” said Carl Haub in a webinar on July 19 to launch the Population Reference Bureau’s (PRB) 50th annual World Population Data Sheet. This year, the report explores aging populations in more developed countries, rapid population growth in less developed countries, and the increased global prevalence of non-communicable diseases in an interactive map, which concisely illustrates global trends. PRB estimates that the world’s population is 7,057,075,000 as of mid-2012; the global population crossed the seven billion threshold in October 2011.
“The most rapid population growth in many ways [occurs in] the countries that can least afford it,” said Carl Haub in a webinar on July 19 to launch the Population Reference Bureau’s (PRB) 50th annual World Population Data Sheet. This year, the report explores aging populations in more developed countries, rapid population growth in less developed countries, and the increased global prevalence of non-communicable diseases in an interactive map, which concisely illustrates global trends. PRB estimates that the world’s population is 7,057,075,000 as of mid-2012; the global population crossed the seven billion threshold in October 2011.
Aging Europe and East Asia
Haub explained that population growth in Europe has been declining since the 1970s and is more or less a “pre-programmed destiny” for these countries. People of child-bearing ages make up a smaller percent of the population in many more developed countries, so unless there is an “enormous increase” in total fertility rates, these populations will continue to decline for the foreseeable future.
Haub noted that these aging populations are unprecedented. In Germany and Italy, for example, 21 percent are over the age of 65; many other European countries have similar figures, as do other developed countries like Japan and South Korea. PRB expects these percentages to increase throughout the next century and for European countries to struggle to support greater numbers of retirees.
Many such states have already found it difficult to raise the retirement age, even though medical advances allow people to work until later ages. PRB projects that in Japan, 42 percent of their population will be over the age of 60 in 2050; if such a large percentage of the population is no longer in the labor force, it will be difficult for to find the resources to support them.
The report shows that the United States, on the other hand, is still experiencing modest population growth. The higher birthrate is in part due to immigration, as recent immigrants to the United States tend to have more children. Haub noted that European states have been reluctant to accept greater numbers of migrants to try to reverse their declining population.
Youthful Developing Countries
While the demographic destiny of aging countries is somewhat determined, the future for less developed countries is more uncertain. Many countries in sub-Saharan Africa, the Middle East, and South Asia have large and growing youth populations, and how many children these “future parents” will have is uncertain. That uncertainty is underscored by the variety of scenarios for future population growth. The UN has four variants – high, medium, low, and constant fertility – which vary considerably in their projections for future populations, and PRB’s global projections for 2050 are some 600 million people more than the commonly-used medium variant UN projection.
Rapid growth in the least developed countries is hardly a new phenomenon, but PRB breaks down the numbers to an impressive degree. The 2012 Data Sheet provides updated net migration rates, projected population as a multiple of today’s, infant mortality rates, rate of natural increase, and other basic statistics. PRB also provides population pyramids from the wealthiest and poorest quintiles of the population of Malawi, as an example of the utility of desegregating data to better allocate resources to the underserved. They found that while birthrates have begun to decline for the wealthiest one-fifth of Malawians, the poorest citizens still have a total fertility rate of over seven children per woman.
Measuring Health Systems
Devastating infectious diseases – malaria, tuberculosis, and HIV/AIDS – have long been entrenched in some of the least developed and most rapidly growing parts of the world. But this year, PRB began to assess health on a broader level by tracking deaths attributed to non-communicable diseases as well. Diseases like cardiovascular disease, diabetes, respiratory illness, and cancer are leading causes of death in developed countries, but they have also increased in prevalence in developing countries at an alarming rate.
PRB is not the only organization to take note of the change in disease predominance. The World Health Organization has issued guidelines targeting four factors which increase the risk of these illnesses: tobacco use, alcohol abuse, poor diet/obesity, and physical inactivity. The UN also called a special session last September to discuss non-communicable diseases. President of PRB Wendy Baldwin noted that the last such discussion on a health issue was 10 years ago about HIV/AIDS.
Baldwin also pointed out that non-communicable diseases can increase the burden on the health systems of developing countries even more so than in developed states. She reported that in south Asia, for example, people have heart attacks on average six years earlier than people in developed countries, meaning more families lose their primary breadwinners.
The risk factors for these non-communicable diseases are difficult to target, especially with increasing urbanization in developing countries. But in a video accompanying the report, Baldwin mentioned that raising the price of cigarettes is an effective way to reduce tobacco consumption, especially for youth. Some countries have also made progress in increasing physical activity through sports programs and making urban areas safer for pedestrians. “The low and middle income countries have a real opportunity to take really positive steps to confront that rise in non-communicable diseases and to address the risk factors that drive them,” she said.
The Data Sheet Over Time
The World Population Data Sheet has long been a vital resource for those in the population, health, and environment fields and has grown to include far more data than its first iteration in 1962. At first, the sheet had only four indicators: a population estimate for the year, annual rate of increase, crude birth rate, and crude death rate. Over time, PRB began measuring a greater number of key figures like infant mortality and life expectancy at birth. Population projections, a staple of the current version, were not added until 1978, perhaps in response to the inception of the United Nations World Population Projections in 1974.
Over the past five decades, the data sheet has been witness to some major shifts in global population trends. While PRB discourages researchers from comparing past data to current figures because the measures and methods of gathering information have likely changed over time, it is still possible to see the rise of importance in several trends based on the indicators PRB chose to focus on each year. For example, extremely young populations have been found to have profound effects on a country’s stability and prosperity, as have aging populations. The 1966 data sheet was the first to measure the percentage of the population under the age of 15, and it didn’t become a consistent data point until 1977.
The number of people living in cities in the developing world surpassed those in the developed in 1970, according to the UN, and in 1972, PRB began tracking the percentage of populations living in urban areas. HIV/AIDS indicators were added in 2000, as global awareness and a commitment to fighting the disease was rising.
PRB’s demonstrated commitment to continually adding more data and refining existing projections makes the data sheet is a valuable resource to those studying the problems of today and the future. Fifty years on, the amount of information collected is staggering. The data sheet provides a glimpse at not just how many people there are in the world, but also where and how they live.
