“Losing my religion”*…

Shifting religious affiliations in the U.S. have generated lots of comment (e.g., Friday’s New York Times: “The Christian Right Is in Decline, and It’s Taking America With It“). It’s worth taking a comprehensive look at the data on which those takes are based; there’s even more to see…

Seven in ten Americans (70%) identify as Christian, including more than four in ten who identify as white Christian and more than one-quarter who identify as Christian of color. Nearly one in four Americans (23%) are religiously unaffiliated, and 5% identify with non-Christian religions.

The most substantial cultural and political divides are between white Christians and Christians of color. More than four in ten Americans (44%) identify as white Christian, including white evangelical Protestants (14%), white mainline (non-evangelical) Protestants (16%), and white Catholics (12%), as well as small percentages who identify as Latter-day Saint (Mormon), Jehovah’s Witness, and Orthodox Christian. Christians of color include Hispanic Catholics (8%), Black Protestants (7%), Hispanic Protestants (4%), other Protestants of color (4%), and other Catholics of color (2%). The rest of religiously affiliated Americans belong to non-Christian groups, including 1% who are Jewish, 1% Muslim, 1% Buddhist, 0.5% Hindu, and 1% who identify with other religions. Religiously unaffiliated Americans comprise those who do not claim any particular religious affiliation (17%) and those who identify as atheist (3%) or agnostic (3%).

Over the last few decades, the proportion of the U.S. population that is white Christian has declined by nearly one-third. As recently as 1996, almost two-thirds of Americans (65%) identified as white and Christian. By 2006, that had declined to 54%, and by 2017 it was down to 43%. The proportion of white Christians hit a low point in 2018, at 42%, and rebounded slightly in 2019 and 2020, to 44%. That tick upward indicates the decline is slowing from its pace of losing roughly 11% per decade.

The slight increase in white Christians between 2018 and 2020 was driven primarily by an uptick in the proportion of white mainline (non-evangelical) Protestants and a stabilization in the proportion of white Catholics. Since 2007, white mainline (non-evangelical) Protestants have declined from 19% of the population to a low of 13% in 2016, but the last three years have seen small but steady increases, up to 16% in 2020. White Catholics have also declined from a high point of 16% of the population in 2008, and their low point of 11% occurred in 2018. It is unclear if the bump back up to 12% in 2020 indicates a new trend.

Since 2006, white evangelical Protestants have experienced the most precipitous drop in affiliation, shrinking from 23% of Americans in 2006 to 14% in 2020. That proportion has generally held steady since 2017 (15% in 2017, 2018, and 2019).

Disaffiliating white Christians have fueled the growth of the religiously unaffiliated during this period. Only 16% of Americans reported being religiously unaffiliated in 2007; this proportion rose to 19% by 2012, and then gained roughly a percentage point each year from 2012 to 2017. Reflecting the patterns above, the proportion of religiously unaffiliated Americans hit a high point of 26% in 2018 but has since slightly declined, to 23% in 2020.

The increase in proportion of religiously unaffiliated Americans has occurred across all age groups but has been most pronounced among young Americans. In 1986, only 10% of those ages 18–29 identified as religiously unaffiliated. In 2016, that number had increased to 38%, and declined slightly in 2020, to 36%.

Americans ages 18–29 are the most religiously diverse age group. Although a majority (54%) are Christian, only 28% are white Christians (including 12% who are white mainline Protestants, 8% who are white Catholics, and 7% who are white evangelical Protestants), while 26% are Christians of color (including 9% who are Hispanic Catholics, 5% who are Hispanic Protestants, 5% who are Black Protestants, 2% who are multiracial Christians, 2% who are AAPI Christians, and 1% who are Native American Christians). More than one-third of young Americans (36%) are religiously unaffiliated, and the remainder are Jewish (2%), Muslim (2%), Buddhist (1%), Hindu (1%), or another religion (1%).

Americans ages 65 and older are the only group whose religious profile has changed significantly since 2013. Among Americans 65 and older, the proportion of white evangelical Protestants dropped from 26% in 2013 to 22% in 2020, and the proportion of white Catholics dropped from 18% in 2013 to 15% in 2020. By contrast, the proportion of religiously unaffiliated seniors increased from 11% in 2013 to 14% in 2020.

White evangelical Protestants are the oldest religious group in the U.S., with a median age of 56, compared to the median age in the country of 47. White Catholics and Unitarian Universalists have median ages of 54 and 53 years old, respectively. Black Protestants and white mainline Protestants have a median age of 50. All other groups have median ages below 50: Jehovah’s Witnesses (49), Jewish Americans (48), Latter-day Saints (47), Orthodox Christians (42), Hispanic Catholics (42), Hispanic Protestants (39), religiously unaffiliated people (38), Buddhists (36), Hindus (36), and Muslims (33). In the youngest groups, one-third of Hindu (33%) and Buddhist (34%) Americans and 42% of Muslim Americans are in the 18–29 age category.

As we ponder piety, we might send evangelical birthday greetings to Bardaisan; he was born on this date in 154. A scientist, scholar, astrologer, philosopher, hymnographer, and poet, he was the first known Syriac literary author. A key figure among the Gnostics, he founded the Bardaisanites and was central to the Christianization of Rome (indeed, he is said to have converted prince Abgar IX).

As we celebrate clarity, we might spare a thought for the mathematician, biologist, historian of science, literary critic, poet, and inventor Jacob Bronowski; he died on this date in 1974.  Bronowski is probably best remembered as the writer (and host) of the epochal 1973 BBC television documentary series (and accompanying book), The Ascent of Man (the title of which was a play on the title of Darwin’s second book on evolution, The Descent of Man)… the thirteen-part series, a survey of the history of science–  from rock tools to relativity– and its place in civilizations, is still an extraordinary treat.  It’s available at libraries, on DVD, or (occasionally) on streaming services.




“A better world won’t come about simply because we use data; data has its dark underside.”*…




Data isn’t the new oil, it’s the new CO2. It’s a common trope in the data/tech field to say that “data is the new oil”. The basic idea being – it’s a new resource that is being extracted, it is valuable, and is a raw product that fuels other industries. But it also implies that data in inherently valuable in and of itself and that “my data” is valuable, a resource that I really should tap in to.

In reality, we are more impacted by other people’s data (with whom we are grouped) than we are by data about us. As I have written in the MIT Technology Review – “even if you deny consent to ‘your’ data being used, an organisation can use data about other people to make statistical extrapolations that affect you.” We are bound by other people’s consent. Our own consent (or lack thereof) is becoming increasingly irrelevant. We won’t solve the societal problems pervasive data surveillance is causing by rushing through online consent forms. If you see data as CO2, it becomes clearer that its impacts are societal not solely individual. My neighbour’s car emissions, the emissions from a factory on a different continent, impact me more than my own emissions or lack thereof. This isn’t to abdicate individual responsibility or harm. It’s adding a new lens that we too often miss entirely.

We should not endlessly be defending arguments along the lines that “people choose to willingly give up their freedom in exchange for free stuff online”. The argument is flawed for two reasons. First the reason that is usually given – people have no choice but to consent in order to access the service, so consent is manufactured.  We are not exercising choice in providing data but rather resigned to the fact that they have no choice in the matter.

The second, less well known but just as powerful, argument is that we are not only bound by other people’s data; we are bound by other people’s consent.  In an era of machine learning-driven group profiling, this effectively renders my denial of consent meaningless. Even if I withhold consent, say I refuse to use Facebook or Twitter or Amazon, the fact that everyone around me has joined means there are just as many data points about me to target and surveil. The issue is systemic, it is not one where a lone individual can make a choice and opt out of the system. We perpetuate this myth by talking about data as our own individual “oil”, ready to sell to the highest bidder. In reality I have little control over this supposed resource which acts more like an atmospheric pollutant, impacting me and others in myriads of indirect ways. There are more relations – direct and indirect – between data related to me, data about me, data inferred about me via others than I can possibly imagine, let alone control with the tools we have at our disposal today.

Because of this, we need a social, systemic approach to deal with our data emissions. An environmental approach to data rights as I’ve argued previously. But first let’s all admit that the line of inquiry defending pervasive surveillance in the name of “individual freedom” and individual consent gets us nowhere closer to understanding the threats we are facing.

Martin Tisné argues for an “environmental” approach to data rights: “Data isn’t the new oil, it’s the new CO2.”

Lest one think that we couldn’t/shouldn’t have seen this (and related issues like over dependence on algorithms, the digital divide, et al.) coming, see also Paul Baran‘s prescient 1968 essay, “On the Future Computer Era,” one of the last pieces he did at RAND, before co-leading the spin-off of The Institute for the Future.

As we ponder privacy, we might recall that it was on this date in 1981 that IBM released IBM model number 5150– AKA the IBM PC– the original version and progenitor of the IBM PC compatible hardware platform. Since the machine was based on open architecture, within a short time of its introduction, third-party suppliers of peripheral devices, expansion cards, and software proliferated; the influence of the IBM PC on the personal computer market was substantial in standardizing a platform for personal computers (and creating a market for Microsoft’s operating system– first PC DOS, then Windows– on which the PC platform ran).  “IBM compatible” became an important criterion for sales growth; after the 1980s, only the Apple Macintosh family kept a significant share of the microcomputer market without compatibility with the IBM personal computer.

“Big Data is like teenage sex: everyone talks about it, nobody really knows how to do it, everyone thinks everyone else is doing it, so everyone claims they are doing it”*…




You’ve probably heard of kilobytes, megabytes, gigabytes, or even terabytes.

These data units are common everyday amounts that the average person may run into. Units this size may be big enough to quantify the amount of data sent in an email attachment, or the data stored on a hard drive, for example.

In the coming years, however, these common units will begin to seem more quaint – that’s because the entire digital universe is expected to reach 44 zettabytes by 2020.

If this number is correct, it will mean there are 40 times more bytes than there are stars in the observable universe…

As we revel in really, really big numbers, we might spare a thought for Edgar Frank “Ted” Codd; he died on this date in 2003.  A distinguished computer scientist who did important work on cellular automata, he is best remembered as the father of computer databases– as the person who laid the foundation for for relational databases, for storing and retrieving information in computer records.

“I’ll let you be in my dreams if I can be in yours”*…




From Glenn Macdonald (in his capacity as Spotify’s genre taxonomist– or as he put’s it “mechanic of the spiritual compases of erratic discovery robots that run on love”)

This is a mapping of genres to words, and words to genres, using words that are used distinctively in the titles of songs. A genre’s words are ranked by how disproportionately they appear in that genre’s songs’ titles compared to all songs. A word’s genres are ranked by the position of that word in each genre’s word list. 1525 genres and 4712 words qualify.

As we slip on the headphones, we might spare a thought for Sir George Henry Martin; he died on this date in 2016.  A record producer, arranger, composer, conductor, audio engineer, and musician, Martin began his career as a producer of comedy and novelty records in the early 1950s, working with Peter SellersSpike Milligan, and Bernard Cribbins, among others.  In 1962, while working at EMI/Parlophone, Martin was so impressed by Brian Epstein’s enthusiasm, that he agreed to record the Beatles before seeing or hearing them (and despite the fact that they’d been turned down by Decca).

Martin went on to produce 23 number ones on the Billboard Hot 100 chart, 19 of which were by The Beatles.  Indeed, Paul McCartney referred to Martin as “the fifth Beatle.”  He also produced chart topping hits for McCartney (“Say Say Say” with Michael Jackson and “Ebony and Ivory” with Stevie Wonder), Elton John (“Candle in the Wind”) and America (“Sister Golden Hair”).
