Indexed References
via Twitter

My @DemographicDoom Twitter account isn't just a series of tweets; it is an elaborate indexing system for demographic references. As I encounter references relevant to my thesis, I compose them as tweets, indexed by a series of hashtags that should be unique to this account. I include both references that support my position and those that coherently oppose it. Tweets may also record my own original work and various housekeeping events. This system was started 7 April 2019. Older references can be cound on the Structured References page. Videos are indexed on YouTube Playlists.

This is a very active twitter account, essentially building a reference database, so you may not want to follow it directly. See bottom of page for further notes.


Hashtags below concern both the demographic crisis in each country and its looming debt or governance problems.

China [One Child Policy] · Japan · Estonia · Europe · Italy · Latvia · Lithuania · Nigeria · Pakistan · Poland · Russia · Singapore · South Korea · Sudan & South Sudan · Switzerland · Turkey · United Kingdom · USA [USA Debt] · World

Housekeeping Functions

#ddoom_originalLinks related to my own original work. The tag can be used for anything I produced myself, as opposed to references from third parties. This tag is intended for substantial accomplishments like new videos (#ddoom_videorelease), written works and terms invented (#ddoom_mynewterm). For routine housekeeping functions, like new hashtags, #ddoom_housekeeping is used instead. (Differentiated on 19 Apr 2019.)
#ddoom_videoreleaseTweets announcing the release of my own original video posted on the DD YouTube Account.
#ddoom_milestone Items recording a transitional event in the evolution of my Demographic Doom project. Alternatively, tweets may be flagged with #ddoom_timeline for lesser events whose dates I want to record but that don't constitute "milestones". (#ddoom_milestone and #ddoom_timeline shouldn't be used in the same tweet.)
#ddoom_mynewtermTweets announcing my invention of a new term. Also tagged with #ddoom_glossary>#ddoom_glossary, because the term has presumably been entered in the Glossary.
#ddoom_timelineRoutine changes to the project that don't consistute "Milestones". (#ddoom_timeline can be applied only if #ddoom_milestone and #ddoom_housekeeping don't apply.) Tagging a tweet is similar to adding an item to the Timeline. The Timeline is generally preferred because it is always listed in chronological order. I may use a tweet instead if I don't have time to add something to the Timeline or I want an official Twitter datestamp.
#ddoom_housekeeping The announcement of minor structural changes to the project that don't involve any substantial content. (For example, creating new hashtags, tagged #ddoom_hashtag.)
#ddoom_hashtagThe announcement of new Twitter hashtags. These tweets always start: "#ddoom_newhash is my new hashtag for..." Hashtag announcements generally include only topics and housekeeping functions; they do not include countries, media sources, people and organizations.
#ddoom_videoplaylistHighlights new and existing video playlists on the >DD YouTube Account. These are lists of videos, mostly from third parties, fully indexed on the Video Page.
#ddoom_manuscript Announcements relating to the book manuscript I am currently working on, currently The Fertility Manifesto (started 18 April 2019). (Also tagged #ddoom_original.) Significant Manuscript changes are also recorded on the Timeline page. See separate tag #ddoom_footnote for support of factual claims.
#ddoom_footnote Virtual footnote to the Fertility Manifesto manuscript. Intended to support some factual claim I make as I am writing. (NOT tagged with #ddoom_manuscript)


#ddoom_ageconflictConflict between generations, especially the high political power of the old.
#ddoom_antinatalismThe philosophy contending that having children is morally wrong.
#ddoom_babyboomConcerning the U.S. Baby Boom of 1946-1964 and its long-term aftermath. May also include the baby booms of other countries.
#ddoom_complexityConcerning bureaucratic complexity and its costs to society.
#ddoom_conspiracyConspiracy theories relating to population.
#ddoom_contrarianOpinions that are contrary to accepted wisdom or views I express (or example, claiming there is little risk of recession).
#ddoom_debtArticles concerning unsustainable debt, both public and private.
#ddoom_debtusaArticles concerning unsustainable debt in the USA. (Also tagged with #ddoom_debt)
#ddoom_economicsArticles concerning economic issues and definitions, excluding recession. (#ddoom_economics and #ddoom_recession appear in the same tweet only rarely.)
#ddoom_migrationConcerning the mass movement of people between countries and regions. Includes immigration issues and refugee crises.
#ddoom_talentflowThe movement of highly skilled talent from one country to another. Also tagged as #ddoom_migration but is more restrictive than this tag since skill must be involved.
#ddoom_mortalityConcerning death statistics.
#ddoom_familyConcerning the structure and functioning of the family, both present and future (#ddoom_futurefamily)
#ddoom_fertilityConcerning fertility, or the number of babies per woman, as well as the attempts by individuals to conceive children, or deciding whether to have them.
#ddoom_futurefamilyConcerning possible family structure in the future. Also tagged as #ddoom_family
#ddoom_nuclearfamilyThe trials and tribulations of the traditional nuclear family.
#ddoom_polling Results of public opinion polls. (Excluded in #ddoom_statistics.) In my view, polling data isn't strictly "demographic", because the opinions of the public can change on a whim, so I don't tweet many public opinion polls.
#ddoom_recessionArticles concerning a forthcoming recession... or worse!
#ddoom_statisticsDemographic statistics (excludes #ddoom_polling)

Years Before 2019 Any references that were produced before 2019 are tagged with their year of original publication, including: 2006 · 2016 · 2017 · 2018

Starting on 7 April 2019, tweets are indexed via hashtags that begin #ddoom_. For example, to find all tweets on China, see #ddoom_china. This system is intended to replace the existing Structured References page, which was too difficult to maintain. (That page is preserved for older references, but no new articles will be added.) I can't prevent others from using these hashtags, but I hope people will employ them according to the same standards I use. (If possible, also add the hashtag #ddoom_x to indicate that this tweet was externally produced.)

Twitter posts are indexed by topic, country and media source according to the hashtags listed below. Click on the link for the relevant tweets. Unfortunately, the order these tweets are displayed is arbitrary, determined by Twitter.

This Twitter hashtag system is based on the system already implemented for Instagram. (Those hashtags are indexed on the Video page.) Twitter hashtags roughly correspond to those on Instagram, but there could be some subtle differences. For one thing, there are a lot my hashtags on Twitter. Instagram hashtags can also be retroactively changed for existing posts, while Twitter hashtags cannot.

The Twitter account is used chiefly for print references and other text-based events. Videos are rarely included here (except my own) because they are indexed separately in video playlists. Short video excerpts are posted on Instagram and are not announced or duplicated on Twitter.

The @DemographicDoom account is very active with potentially dozens of tweets a days (interspersed with periods of inactivity). Unless you are a hardcore demographics fan, you may not wish to follow this account directly. Instead you can simply access it as needed via the hashtags above.

History: This hashtag system was started on 7 April 2019 and further developed in the following weeks. (No significant hashtags are present before that date. For those references, see the Structured References page.) The hashtags are continuously expanding, but most old hashtags will continue to be supported. (If I change how a hashtag is used or spelled, I will note it in a tweet that includes both new and old hashtags.) Since old tweets can't be changed, older tweets may not take advantage of newer hashtags. Starting 19 April 2019, I try to post a new stand-alone tweet for each new hashtag created, tagged as #ddoom_hashtag.
