Propose merging:
Nominator's rationale: per WP:SMALLCAT. These ten by-year categories contain only 26 articles in total, i.e. an average of 2.6 pages per category. Only one of them has more than 4 pages.
Most cities just have by-decade categories. Compare the large number of city categories in the by-continent sub-categories of Category:Decades by city with the sparse set in Category:Years by city.
Per WP:SMALLCAT, small categories are a nuisance to navigate. Chronology categories are most useful when part of an established series. So we don't split up decade categories unless we have enough articles in the set to make the by-year categories more of a meal than a crumb. --BrownHairedGirl (talk) • (contribs) 23:37, 9 September 2020‎ (UTC)[reply]

Nominator's rationale: Overly specific category that doesn't seem defining. Note: category creator has been banned from creating categories due to constantly creating unnecessary categories. See: [1] JDDJS (talk to me • see what I've done) 22:59, 9 September 2020 (UTC)[reply]

  • All the (dis)establishment container categories:
    • Category:Establishments in Hamburg by century
    • Category:Establishments in Hamburg by decade
    • Category:Establishments in Hamburg by year
    • Category:Disestablishments in Hamburg by century
    • Category:Disestablishments in Hamburg by decade
    • Category:Disestablishments in Hamburg by year
    • Category:19th-century establishments in Hamburg
    • Category:19th-century disestablishments in Hamburg
  • All the year categories which are just containers:
    • Category:Years in Hamburg
    • Category:Years of the 19th century in Hamburg
    • Category:Years of the 21st century in Hamburg
    • Category:1814 in Hamburg
    • Category:1824 in Hamburg
    • Category:1860 in Hamburg
    • Category:1861 in Hamburg
    • Category:1863 in Hamburg
    • Category:1867 in Hamburg
    • Category:1868 in Hamburg
    • Category:1869 in Hamburg
Nominator's rationale: per WP:SMALLCAT. This is a big nest of very small categories:
  • Excluding the (dis)establishment categories, the total number of articles in "YYYY in Hamburg" categories:
    • Category:Years of the 19th century in Hamburg+subcats: 1 articles
    • Category:Years of the 21st century in Hamburg+subcats: 10 articles in 3 by-year categories
  • Taking only the establishment & disestablishment categories
  • Category:Disestablishments in Hamburg by year‎+subcats: 1 article
  • Category:Establishments in Hamburg by year‎+subcats: 13 articles in 11 by-year categories
That is a total of 25 articles in a nest of 36 categories.
As of now, we have nowhere near enough articles on by-year topics in the history of Hamburg to make a by-year category tree useful navigation. So this nomination proposes merging all the establishment and disestablishment categories to the national level, and merging all the year categories to decade categories. This will be in line with the usual category structure for cities and other national subdivisions (Hamburg is both a city and a state of Germany). --BrownHairedGirl (talk) • (contribs) 19:41, 9 September 2020 (UTC)[reply]
  • Rather dual merge per Carlossuarez46 below, also e.g. to Category:19th-century establishments in Hamburg (so keep the century categories). Marcocapelle (talk) 06:21, 11 September 2020 (UTC)[reply]
  • We do categorize by independent polity, but not necessarily by year. By decade or even by century can also be appropriate. Marcocapelle (talk) 06:15, 11 September 2020 (UTC)[reply]
  • For decades there is not enough, but keeping centuries is reasonable. For example, the whole of the 19th century only contains 12 articles. Marcocapelle (talk) 06:20, 13 September 2020 (UTC)[reply]

Years in cities without a wider series

The following is an archived discussion concerning one or more categories. Please do not modify it. Subsequent comments should be made on an appropriate discussion page (such as the category's talk page or in a deletion review). No further edits should be made to this section.
The result of the discussion was: Merge/delete Timrollpickering (talk) 10:57, 23 September 2020 (UTC)[reply]
Nominator's rationale: Per WP:SMALLCAT. Each of these cities has a well-established set of decade cats: Category:Decades in Ankara, Category:Decades in Baghdad, and Category:Decades in Beirut. These isolated year categories are an impediment to navigation. The only one of these by-year cats with over 4 articles is Category:2010s in Ankara (population=6) ... but its parent Category:2010s in Ankara has only 12 articles, so there is no need to split up the decade into tiny chunks.
Most cities just have by-decade categories. Compare the large number of city categories in the by-continent sub-categories of Category:Decades by city with the sparse set in Category:Years by city.
Only the largest cities in developed nations (basically the so-called "world cities") have enough articles to need by-year categories. See e.g. Category:Years in London and Category:Years in New York City. Please note that this is not some sort of judgement on the merits or significance of any city. The issue here is simply navigation, which per WP:CAT is the main purpose of categories: per WP:SMALLCAT, small categories are a nuisance to navigate. Chronology categories are most useful when part of an established series. So we don't split up decade categories unless we have enough articles in the set to make the by-year categories more of a meal than a crumb. --BrownHairedGirl (talk) • (contribs) 16:27, 9 September 2020 (UTC)[reply]

Nominator's rationale: per WP:SMALLCAT. These are the only by-year categories for Austin, and they each contain only a single article. --BrownHairedGirl (talk) • (contribs) 15:08, 9 September 2020 (UTC)[reply]

Nominator's rationale: per WP:SMALLCAT. These 44 by-year categories contain a total of 257 articles, an average of 5.8 per category, which at first glance sounds OK: marginally beyond SMALLCAT territory.
However, https://petscan.wmflabs.org/?psid=17314610 shows that 159 of those pages are in Category:Sports in Illinois by year. Most of those sports articles are also categorised in sporting series categories, so they are adequately categorised already. That leaves only 97 non-sporting topics split over these 44 Chicago-by-year categories(avg 2.2 per year).
This is not as clearcut a case as #Years in Dallas and #Years in Phoenix below, but I still think that the Chicago-by-year categorises are not adding navigational value, and that years are too fine a time unit for useful categorisation of Chicago. --BrownHairedGirl (talk) • (contribs) 14:37, 9 September 2020 (UTC)[reply]

Nominator's rationale: per WP:SMALLCAT. These 31 by-year categories contain a total of only 76 articles, i.e. an average of only 2.5 per category. Seventeen of the categories (i.e. over half of them) contain only one page each.
Most of those 76 pages are sporting topics, which are already well-categorised elsewhere: https://petscan.wmflabs.org/?psid=17314498 shows that 66 of those 76 articles are categorised under Category:Sports in Texas by year.
It seems that we don't yet have enough coverage of Dallas to justify by-year categories for the city. --BrownHairedGirl (talk) • (contribs) 13:57, 9 September 2020 (UTC)[reply]

Nominator's rationale: There is no obvious distinction in terms of stated definitions and member articles between these two categories, and no attempt to define how "scientific" research method journals differ from "generic" research method journals. The impression to the reader is that there's a battle going on to decide which research methods journals qualify as "science" meta-journals, tending to a non-world point of view - most of the world's research community sees a spectrum from the harder more quantitative sciences to the softer generally more qualitative ones. I don't seem to see any research methods journals focussing on highly qualitative science. I suspect that there's also an accident of editing history; the "generic" category was created in 2007, the "specific" category was created in 2018, probably without noticing the generic one or attempting to tidy up. For example, Sociological Methods & Research is currently classified in the generic, not scientific, category but includes papers such as "Improving and Validating Survey Estimates of Religious Demography Using Bayesian Multilevel Models and Poststratification" and "Optimizing Count Responses in Surveys: A Machine-learning Approach" and "Estimating the Proportion of a Categorical Variable With Probit Regression" - these all claim (by their titles) to use formal statistical methods and appear aimed at improving specific scientific methods.
