This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 13th (it will be out in January 2020), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

You can download an iPhone app for the 13th edition from the App Store (search for Weeks Population).

Incomes are up in the U.S., but so is inequality

The U.S. Census Bureau today brought out data from the 2018 American Community Survey, and it was a combination of good news and bad news. The good news is that median household income has been generally on the rise, and the percent of the population living below the poverty line has declined. The changes are not huge, but they are in the right direction.
Median household income between 2017 and 2018 increased for all households across all major race and Hispanic origin groups. Median household income ranged from $87,243 for Asian households (up 2.1%) to $41,511 for black households (up 1.5%). Median household income for households with non-Hispanic white householders increased by 1.0% to $67,937 in 2018. Households with Hispanic householders increased by 1.5% to $51,404 in 2018.
In 2018, 13.1% of the U.S. population had income below the poverty level, down from 13.4% in 2017. This is the fifth consecutive annual decline in the ACS national poverty rate.
This good news was tempered by the finding that income inequality continues to get more extreme. The NPR program "Marketplace" covered this development this morning, and they were able to interview Beth Jarosz from PRB:
Income inequality increased in nine states, including California. That’s a reflection of the effects of the tech boom, according to Beth Jarosz, a demographer with the nonprofit Population Reference Bureau.

In other words, Jarosz said, the contrast between “the level of income in Silicon Valley compared to the really extraordinarily high poverty rate in a county like Imperial County, where the economy is predominantly agricultural and there often is not much work for people who live there.” Jarosz says the same contrast may be behind increasing inequality in other states.
The hi-tech sectors have been raking in a disproportionate share of the nation's wealth, while the quality of other jobs seems to be on the decline, leaving average families at a relative disadvantage, even if things aren't awful. For more on this, I recommend taking a look at this month's issue of The Russell Sage Foundation Journal of the Social Sciences, edited by David Howell and Arne Kalleberg and devoted to "Changing Job Quality: Causes, Consequences, and Challenges."

Remembering Past PAA President Sidney Goldstein

The arrival today of the latest IUSSP newsletter brought the news about the death last month of Sidney Goldstein, who was president of the Population Association of America back in 1976. He died just one day after celebrating his 92nd birthday. He had retired to Lexington, Kentucky, although most of his career was spent at Brown University, where he helped establish, and then directed, their Population Studies and Training Center. This has long been an important resource in demography, as another Past PAA President, Robert Moffitt, recently discussed in his interview with the PAA History Committee. Here's a nice synopsis of some of Goldstein's important work in demography:
Sid’s specific area of interest was the migration of people within countries, especially their movement from rural to urban areas. Beginning with analyses of migration in the United States and Denmark, his focus shifted to less developed countries, including Thailand, China, Vietnam, Ethiopia, Guatemala, and South Africa. In each case, he was especially interested in the impact of rural-urban migration on the welfare and life patterns of the migrants and how they differed from those who were residentially stable. An important component of his work in these countries was the development of local expertise, so that the work that he had begun could be carried further by in-country researchers.
You can read more about his professional life in an interview that Jean van der Tak, former PAA Historian, conducted with him many years ago. It is on the website of the Population Association of America (it starts on page 313 of that document). Check out this rather amazing exchange between Jean (VDT) and Sidney Goldstein:
VDT: And you went through your Ph.D. program in just two years. You got the degree in 1953.
GOLDSTEIN: Was it that soon?
VDT: Yes. And Charlie Westoff and Richard Easterlin got Ph.D.s at Penn the same year.
GOLDSTEIN: Right. I still have movies of that commencement, in which the three of us are marching together down the line.
VDT: You marched together a long way in the same field.
GOLDSTEIN: I always thought that was symbolic. I've often thought back to that commencement, the three of us being together. And a number of years later, the three of us were presidents of PAA almost consecutively [Westoff, 1974-75; Goldstein, 1976-77; Easterlin, 1978].

How to Avoid Hunger and Environmental Catastrophe

A new report has just been issued on the threats to our food supply and environment. ABC News has the story about the report, which comes from the Food and Land Use Coalition. I had not heard of them until today, but I see that two of the partners in the coalition are IIASA and the World Resources Institute--both of which are very high quality organizations to whom we should pay attention.

The report comes out now to coincide with the United Nations Climate Action Summit, which will be held in New York beginning next week, and here are two key background notes:
The world’s food supply largely relies on just five countries – the United States, Argentina, Brazil, China and India – for 60% of its calories. Additionally, much of the world’s food supply depends mostly on four crops – rice, wheat, potatoes and maize, a concentration that leaves the food supply vulnerable to risk.
Food and land use systems are currently responsible for up to 30% of global greenhouse gas emissions, according to the report. The emissions from the agricultural system alone will heat the environment beyond the level that scientists have warned about.
And here are two things that are important for the world to do:
The report outlines ways in which money can be better spent to reforest land, and promote biodiversity, and how land can be used more efficiently at local levels to produce a greater diversity of food crops.
Diversifying crops would mean a change in diet for many people in the developed world. To remain sustainable, the world will have to look to more diverse sources of protein and sharply reduce meat consumption. Experts say these changes will lead to healthier, more varied diets.
The important thing here is that we have to act now. We are spending a lot of money on agricultural subsidies and on growing food for animals rather than people. We need to change how we think about agriculture, the environment, and our diet. Not an easy project, but it beats the alternative.

Urbanization in Bangladesh

The urban transition has been one of the most important changes taking place in the context of the overall demographic transition of the past two centuries. But, despite its role in remaking human society, it rarely gets into the news in any real way. That's why the headline from this week's Economist caught my eye: "Urbanization in  Bangladesh: Life after Dhaka."
In 1974 just 9% of Bangladeshis lived in towns or cities. Today 37% of the country’s 170m people do. In a few decades more than half will. The capital, Dhaka, which attracts the majority of rural migrants, has grown from 3m in 1980 to 18m today. It is “already bursting at the seams”, says Saleemul Huq of the International Centre for Climate Change and Development, a think-tank trying to bolster education and employment in eight places, including Mongla, to help absorb migrants.
Mongla is a small city of 40,000 people whose mayor wants some, or a lot, of those people going to Dhaka to move instead to Mongla, which is about an 8-hour drive south of Dhaka. Why might they be tempted to do that? At least partly because the description of living conditions in Dhaka is reminiscent of European cities in the 19th century.
According to an index compiled by the Economist Intelligence Unit, a sister company to The Economist, Dhaka, notorious for traffic jams and pollution, is the world’s third-least liveable city. Some 60% of residents live in makeshift structures, according to the Centre for Urban Studies (CUS), another think-tank. Many of these slum-dwellers lack access to clean water and sanitation and are at constant risk of eviction. 
In such conditions diseases—especially waterborne ones—thrive. Frequent bouts of illness that stop slum-dwellers from working keep them trapped in poverty, says Abdus Shaheen of Water & Sanitation for the Urban Poor, an NGO. “This, of course, hampers the wider economy, too,” he adds.
The government is working on the problem, including a program to bring better living conditions to rural residents so that they will stay down on the farm. As China found out, however, that is very unlikely to work. Building better cities is the long-term answer.

Are European Countries Abandoning Census-Taking?

No matter how much other information we might collect about people, history suggests that censuses are the best way to know how many people there are in a given place. It was thus a little worrisome to read the new article by Paolo Valente, a statistician in the Social and Demographic Statistics Section at United Nations Economic Commission for Europe, published online by the International Union for the Scientific Study of Population (IUSSP). He points out to us that European countries are going through a process of modernizing the census, which means cutting back on the traditional forms of data collection. Here's his assessment of the upcoming round of 2020 censuses in Europe compared to earlier census rounds:


I'm not so worried about the combination of population registers and census data collection, but the increasing reliance on population registers as the sole enumeration method can be problematic unless we are talking about a highly regimented society that can readily document migration and other demographic events. 

I personally like the U.S. method of using the short-form to gather the demographic essentials of age, sex, race/ethnicity, and household composition, with other more detailed data being gathered on a rolling survey basis through the American Community Survey. To be sure, the process is being modernized by the increased use of Internet responses, and electronic (rather than paper) gathering of data, as Valente points out. But we really do need the census, even if people want to complain about it.
