TESS: Time-sharing Experiments for the Social Sciences
"Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments while also realizing the benefits of working with a large, diverse population of research participants. Investigators submit proposals for experiments, and TESS fields successful proposals for free on a representative sample of adults in the United States using NORC's AmeriSpeak® Panel, a probability-based and highly-respected representative survey platform."

Peter Turchin Home - Peter Turchin
"Peter Turchin is a scientist and an author who wants to understand how human societies evolve, and why we see such a staggering degree of inequality in economic performance and effectiveness of governance among nations (see Research Interests). Peter’s approach to answering these questions blends theory building with the analysis of data. He is the founder of a new transdisciplinary field of Cliodynamics, which uses the tools of complexity science and cultural evolution to study the dynamics of historical empires and modern nation-states."

Gridded Population of the World (GPW), v3 | SEDAC
"Note: "Gridded Population of the World, v4" is now available and supersedes GPWv3. GPWv4 provides gridded population estimates with an output resolution of 30 arc-seconds (approximately 1 km at the equator) for the years 2000, 2005, 2010, 2015, and 2020 based on the results of the 2010 round of censuses, which occurred between 2005 and 2014. "

Web IQ | Pew Research Center's Internet & American Life Project
"American internet users’ knowledge of the modern technology landscape varies widely across a range of topics, according to a new knowledge quiz conducted by the Pew Research Center as part of its ongoing series commemorating the 25th anniversary of the World Wide Web. To take the quiz for yourself before reading the full report, click here. The survey—which was conducted among a nationally representative sample of 1,066 internet users—includes 17 questions on a range of issues related to technology, including: the meaning and usage of common online terms; recognition of famous tech figures; the history of some major technological advances; and the underlying structure of the internet and other technologies."

Human population reduction is not a quick fix for environmental problems
"The planet’s large, growing, and overconsuming human population, especially the increasing affluent component, is rapidly eroding many of the Earth’s natural ecosystems. However, society’s only real policy lever to reduce the human population humanely is to encourage lower per capita fertility. How long might fertility reduction take to make a meaningful impact? We examined various scenarios for global human population change to the year 2100 by adjusting fertility and mortality rates (both chronic and short-term interventions) to determine the plausible range of outcomes. Even one-child policies imposed worldwide and catastrophic mortality events would still likely result in 5–10 billion people by 2100. Because of this demographic momentum, there are no easy ways to change the broad trends of human population size this century."

World population stabilization unlikely this century
"The United Nations (UN) recently released population projections based on data until 2012 and a Bayesian probabilistic methodology. Analysis of these data reveals that, contrary to previous literature, the world population is unlikely to stop growing this century. There is an 80% probability that world population, now 7.2 billion people, will increase to between 9.6 billion and 12.3 billion in 2100. This uncertainty is much smaller than the range from the traditional UN high and low variants. Much of the increase is expected to happen in Africa, in part due to higher fertility rates and a recent slowdown in the pace of fertility decline. Also, the ratio of working-age people to older people is likely to decline substantially in all countries, even those that currently have young populations."

Dencity | Fathom
"Dencity maps population density using circles of various size and hue. Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities. Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined. "

Shanghai Scrap » Unnatural Selection: Missing Girls, Abortion, and the Perversion of Choice
"Skewed sex ratios at birth are now found in many countries with no tradition of infanticide and no one-child policy. By and large, the gap is the result of sex selective abortion."

UnderstandingSociety: Small cities
"A recent post on the suburbs closed with the observation that there is an important "other" social space in the United States beyond the categories of urban, rural, and suburban. These are the small cities throughout the United States where a significant number of people come to maturity and develop their families and careers. I speculated that perhaps there is a distinctive sociology associated with these lesser urban places. Here I will look into this question a bit more fully."

Insufficient data - Charlie's Diary
What is the minimum number of people you need in order to maintain (not necessarily to extend) our current level of technological civilization?

There are huge political ramifications hiding behind this question. Let me unpack them for you.

National Journal Magazine - The Gray And The Brown: The Generational Mismatch
Although cultural disputes often generate the most heat, government budgets are likely to become the central point of conflict between younger minorities and older whites. At the state level, where governors are grappling with persistent deficits, the strains revolve around the choice between raising taxes or cutting spending. At the national level, Congress faces not only that familiar debate but also the competition between investing in education and other programs that benefit children, or spending on those that benefit seniors, primarily Medicare and Social Security.

The Arc of Evolution Is Long and Rarely Bends Towards Advantageous Alleles: Why Does Popular Science Ignore Neutral Theory? : Mike the Mad Biologist
Because that's not the philosophically challenging part. Unless you're a biblical 'literalist', the idea of a creator dude who acts through the mechanism of natural selection isn't too theologically challenging. After all, traits that are beneficial (at least locally and in the short term) increase, while the deleterious ones decrease. Surely, this is the best of all possible worlds..

The neutral theory was developed to make sense of molecular variation. Importantly, it asks a subtly different question about variation. Typically, when you encounter explanations of natural selection, it's usually along the lines of: "There are a bunch of grey ones, and a bunch of brown ones. Under the right ecological circumstances, the grey ones replace the brown ones."

Neutral theory starts from the (obvious) assumption that a novel allele (gene variant) initially occurs as a single copy in a population.
