[DM] Some news links: fertility, population aging, migration, demography is not destiny, Eurabia

Over the past week, I’ve come across some interesting news reports about different trends in different parts of the world. I have assembled them in a links post at Demography Matters.

  • The Independent noted that the length and severity of the Greek economic crisis means that, for many younger Greeks, the chance to have a family the size they wanted–or the chance to have a family at all–is passing. The Korea Herald, meanwhile, noted that the fertility rate in South Korea likely dipped below 1 child per woman, surely a record low for any nation-state (although some Chinese provinces, to be fair, have seen similar dips).
  • The South China Morning Post argued that Hong Kong, facing rapid population aging, should try to keep its elderly employed. Similar arguments were made over at Bloomberg with regards to the United States, although the American demographic situation is rather less dramatic than Hong Kong’s.
  • Canadian news source Global News noted that, thanks to international migration, the population of the Atlantic Canadian province of Nova Scotia actually experienced net growth. OBC Transeuropa, meanwhile, observed that despite growing emigration from Croatia to richer European Union member-states like Germany and Ireland, labour shortages are drawing substantial numbers of workers not only from the former Yugoslavia but from further afield.
  • At Open Democracy, Oliver Haynes speaking about Brexit argued strongly against assuming simple demographic change will lead to shifts of political opinion. People still need to be convinced.
  • Open Democracy’s Carmen Aguilera, meanwhile, noted that far-right Spanish political party Vox is now making Eurabian arguments, suggesting that Muslim immigrants are but the vanguard of a broader Muslim invasion.

  • Kieran Healy notes the often wild guesses made by Americans at the population size of the United States.
  • Language Hat notes the dislike of Russian aristocrats for the Russian language, and maps London’s different languages.
  • Language Log takes issue with a map of the languages of the world in regards to China, and looks at Cantonese usage in Hong Kong.
  • Languages of the World considers Google Translate.
  • Marginal Revolution examines China’s ideological spectrum and notes a New Zealand database that can predict outcomes for young people.

  • pollotenchegg maps the distribution of refugees in the Ukrainian government-controlled Donbas.
  • The Power and the Money’s Noel Maurer looks at recent fertility increases in post-graduate American women.
  • The Russian Demographics Blog examined the changing nature of migration to and from Russia, looks at the demographic experiences over Belarus, considers the Russian HIV epidemic, and examines the link between fertility and economic shocks in the United States.
  • Savage Minds examines a new book on the Bougainville conflict, looks at racism in Baltimore, and reacts to the earthquake in Nepal.
  • Towleroad and the Volokh Conspiracy note that, properly analyzed, the data of Regnerus actually contradicts his claims about same-sex parents.
  • Zero Geography looks at the hidden biases of geodata.

[DM] “On why demographics mean a near-term recovery in Greece is unlikely”

I’ve a post up at Demography Matters arguing that, whatever the government, the scale of mass migration from Greece is such that economic recovery is not very likely.

[DM] “Some thematic links: France, Ukraine, Russia, Japan, China, South Pacific”

I’ve an extended Demography Matters link post examining in brief situations in the six countries/regions mentioned above. Original content to come tomorrow evening.

[LINK] “Making Babies with 3 Genetic Parents Gets FDA Hearing”

Dina Fine Maron’s Scientific American article concerning new technologies that could marry DNA from three individuals, creating three-parent children, is a good overview of the technology’s position in the United States right now. (I’m for it, for whatever it’s worth, in that preventing inherited mitochondrial DNA diseases in children is a good thing.)

Scientists have already had successes with this type of reproductive approach in monkeys and in human embryos, and are now eager to launch human clinical trials. First, however, they must get the green light from the U.S. Food and Drug Administration, which will convene a public hearing before an advisory committee on February 25.

The technology, called oocyte modification (but sometimes nicknamed “three-parent IVF”), involves scooping out potentially mutated mitochondrial DNA (mtDNA) from a woman’s egg and replacing it with the mtDNA of an unaffected donor woman. The process is designed to prevent the transmission of some debilitating inherited mitochondrial diseases, which can result in vision loss, seizures and other maladies. Such inherited diseases, often unfortunately known by acronyms for complex medical names that include LHON, for Leber’s Hereditary Optic Neuropathy, along with MELAS, MERRF and NARP, occur in about one in every 5,000 live births and are incurable.

Once the mtDNA has been swapped out, the egg could be fertilized in the lab by the father’s sperm and the embryo would be implanted back into mom where pregnancy would proceed. The resulting child would be the genetic offspring of the intended mother but would carry healthy mitochondrial genes from the donor.

[. . .]

Scientists already have evidence for the promise of this type of oocyte modification. Shoukhrat Mitalipov of the Oregon Health & Science University and his colleagues created human embryos in this way, although they did not implant those embryos to make babies. Their findings were published in October 2012 in Nature. Other work from that same team also found that in monkeys the process could lead to the birth of healthy offspring that remained free of complications into adulthood. (Scientific American is part of Nature Publishing Group).

[. . .]

But wading into this type of approach is also fraught with ethical issues. Marcy Darnovsky, executive director of the Center for Genetics and Society, fears that this reproductive approach could soon lead to tampering with other traits, such as intelligence or sports ability. “Life is full of slippery slopes and we need brakes,” she says. “This is described as saving lives but it is not aimed at people who are sick,” she adds. The FDA advisory committee does not plan to consider ethical issues at this meeting. Instead it will focus on the scientific aspects of future clinical trial considerations, including long-term risk of carryover of abnormal mtDNA, the potential benefits and harm to mothers and future children, and the need for multigenerational follow-up in any trials (because female children could pass on mitochondrial disease to future offspring). “Our job will be purely to air the issue and bring it out into the open,” says Evan Snyder, chair of the committee and director of the Stem Cell and Regenerative Biology Program at Sanford–Burnham Medical Research Institute in La Jolla, Calif. “We’re not going to come out at the end of the meeting and say we are advocating for clinical trials or any particular technique. This is educational,” he says.

[DM] “Hans Rosling: Religions and babies”

Over at Demography Matters, I point–thanks to Will Baird–to a 2012 TED talk by the Gapminder Foundation‘s Hans Rosling, examining the question of the relationship between religion and fertility.

[DM] “Notes on Venezuela”

I’ve a post up at Demography Matters taking a look at Venezuela. A country with a bit of a unique population history in Latin America, Venezuela for all of its issues is still a country that some people move to (while others move away).

[DM] “‘Singapore is not serious …'”

I’ve a post up at Demography Matters linking to a post by The Power and the Money’s Noel Maurer that took a look at the actual subsidies, mentioned in passing in the recent post on Singaporean population policy. Briefly, even the various financial incentives offered by the Singaporean government–heavily subsidized fertility treatments, baby bonuses and tax incentives, child care subsidies–aren’t that significant relative to the costs of parenthood.
