Some Demographic Assorted Links

  1. The UN has recently released the 2015 Revision of World Population Prospects (via Bernardo Queiroz)

  2. Cutting edge research behind new population projections

  3. Can Demography Affect Inflation and Monetary Policy? (via MR)

  4. Which countries have the most immigrants?

  5. There are now at least two good open access journals in demography/population studies. The well known Demographic Research (twitter) , and the new International Journal of Population Studies (twitter)

  6. The new Institute for Asian Demographic Research, in Shanghai (via Emilio Zagheni)

  7. In celebration to World Population Day (11th of July), Springer and BioMed have made freely available a selection of free articles that investigate the consequences of the ever increasing population on health, migration and the environment. These papers will be freely available until September 10, 2015

  8. Nice piece in the NYT on the The Unrealized Horrors of Population Explosion

  9. A great series of GIFs showing demographic changes in different counties (ht Conrad Hackett)

Age related CO2 Emissions


Abstract:
This article provides a methodological contribution to the study of the effect of changes in population age structure on carbon dioxide (CO2) emissions. First, I propose a generalization of the IPAT equation to a multisector economy with an age-structured population and discuss the insights that can be obtained in the context of stable population theory. Second, I suggest a statistical model of household consumption as a function of household size and age structure to quantitatively evaluate the extent of economies of scale in consumption of energy-intensive goods, and to estimate age-specific profiles of consumption of energy-intensive goods and of CO2 emissions. Third, I offer an illustration of the methodologies using data for the United States. The analysis shows that per-capita CO2 emissions increase with age until the individual is in his or her 60s, and then emissions tend to decrease. Holding everything else constant, the expected change in U.S. population age distribution during the next four decades is likely to have a small, but noticeable, positive impact on CO2 emissions.

Educational Attainment and the Demographic Dividend

The Economist Magazine has published a short piece where they highlight Wolfgang Lutz's arguments on the importance of educational attainment to the potential benefits countries may get from their demographic dividend.

China's Demographic Future (Part 2)




And here is an excellent paper to understand China's demographic future: "The Future of a Demographic Overachiever: Long-Term Implications of the Demographic Transition in China" published at PDR by Wang Feng. The paper also dicusses the role of the Chinese State in demographic transition. Prof Feng has also presented the paper at Stanford (the audio is available). If you are having difficulties access the paper, try this link.

I have selected a few sentences:


Mortality
  • "In the two decades after 1950, the crude death rate of the Chinese population was reduced by nearly 60 percent, from 18 per thousand in 1950 to 7.6 in 1970."
Life Expectancy 
  • [in 50 years/ 1950-2000] China accomplished what it took these other countries [more developed european countries and US] a century to achieve, an increase in life expectancy from the 40s to over 70 years.
Fertility
  • "In contrast to western european countries, where it took 75 years or longer to complete a fertility transitionfrom a TFR of around 5 to the replacement level, in China a similar decline took only about two decades."
Demographic Transition
  • "In roughly half a century, China completed its transition from a low rate of natural increase due to high mortality and high fertility to a low rate of natural increase as a result of low mortality and low fertility."
Family
  • "Moreover, the large number of families with only one child, often against the will of the parents, presents serious economic and social risks for Chinese families and for society as a whole."

Labor Force and Aging
  • "China’s economic boom has relied on another crucial factor, namely a young and productive labor force. This large labor force, a non-repeatable historical product of the rapid demographic transition, was present fortuitously as the Chinese economy was about to take off."
  • "China’s rapidly shrinking young labor force, a result of very low fertility for nearly two decades, will soon end the era of abundant supply of inexpensive labor that enabled China to become the world’s largest manufacturing center in the last two decades."

My take: China is perhaps one of the few countries that have completed its fertility transition without completing its urban transition. It means that China still has large amount of rural-urban migration potential, which could keep an abundant supply of inexpensive labor for many decades. Perhaps this potential is being underestimated.

Demographic Dependency Ratio

New Geography have just published a piece by Emma Chen and Wendell Cox on the challenges posed by aging and declining fertility. Worth 5 minutes of your time.

The rise and fall of Urban Sociology (?)


Google has scanned 15 million books originally published from 1800 on. And they have also developed the Google Books Ngram Viewer. It's a tool that charts the usage of any word over time in literature and other books (Google books database). One could irresponsibly use it as a proxy for the popularity of words in literature. And I did!
















This chart above shows how often "Urban Sociology" has appeared in the literature (Google database - english literature only) since 1800. It looks to me that the Chicago School have had played an important role in the rising 'popularity' of Urban Sociology*. And it looks that Urban Sociology is not as 'popular' as it used to be....

*obviously, it would be necessary to scrutinize other keywords to conclude this (such as the major researchers in the first Chicago School)




And here are some queries of other keywords of interest:

And my favorites:

Traffic Jam:
















Urban sprawl, compact city, smart city, smart growth, compact growth, New Urbanism.
