Could Influence of the season of birth be better? I'm not sure. --AaThinker (talk) 22:27, 3 May 2009 (UTC)[reply]

Season of birth in destiny

At present time the original text (September 2009) of this article was erased. I don't know - why it was made. Such article was interesting only on separate page. Yes, of course, It was scientific article. But this article showed how season of birth can be a destiny.
Original text was erased. I don't want to know - who did it. I am sorry. It was a good idea. Leonid 2 (talk) 11:17, 12 October 2009 (UTC)[reply]

I don't understand your comment (request,question?). Can you try to clarify, please. Verbal chat 11:29, 12 October 2009 (UTC)[reply]

I reverted back to previous version, because removing all this content is like throwing out the child with the bathwater.Lova Falk talk 13:30, 29 May 2010 (UTC)[reply]

Picture

This article... really does not need a picture. How does the image convey any extra information? I'm going to remove it for now, if anyone disagrees, feel free to respond here, and put it back up. 8bit (talk) 12:30, 27 June 2011 (UTC)[reply]

I like the heatmap-frequency picture a lot. It seems apparent that during the (US American) holidays July 4th or Christmas there are fewer births. Some information on the reasons for these peculiarities would be nice to have in the article. I would assume (but have no sources to back this up) this is because medical professionals induce or postpone births if possible to not fall on (maybe short-staffed) holidays.

It is an interesting and worthwhile chart, but it needs at the very least to have its source disclosed. Ideally a properly structured citation should be provided.

Lack of attribution raises a number of issues: where has the chart come from? What stats and methodology were used to generate it? Are they from a trusted reliable source? etc.

Also there is no information of the time period the chart covers, so we are left in doubt as to its currency.

Lastly the chart is annotated with daggers (e.g. on Christmas Day), implying footnotes, but there are no such notes included. Presumably they were on the original source, but in the absence of any attribution, we are unable to research this further. My mother's birthday has one of these dagger marks and I would certainly like to know how it impacts the data shown. MrEckLeckTick (talk) 10:48, 4 April 2023 (UTC)[reply]

Further to my last post, the heatmap in the current (04 April 2023) version, appears to originate in a revision by @Some1 at 16:47hrs, 29 Jan 2023 - see here.

The edit replaced the previous US-only heatmap and is commented by the text "this image includes the UK", but the source is obscure.

the image appears to be an .svg file uploaded to Wikipedia Commons: https://upload.wikimedia.org/wikipedia/commons/b/b6/Most_common_birthdays.svg

No Commons metadata is presented to the user when the image is opened - perhaps because it is interactive?

The Page Source has this content in a description tag:

"Heat map of the birth ratio of each day to the average in the USA for people born from 1994 to 1999 according to the Center for Disease Control and 2000 to 2014 according to the Social Security Administration (top), and in Wales and England for people born from 1995 to 2014 according to the Office for National Statistics (bottom), also aggregated by month and day of month with 29 February normalised, and minima and maxima in bold by CMG Lee. * Most common birthdays are in September. ; Least common birthdays fall around Christmas, New Year's and April Fools' Days, plus in the USA, Independence Day, Hallowe'en and Thanksgiving. The 13th of each month has fewer birthdays than adjacent days. Valentine's Day is overrepresented in the USA. There is a weak weekly cycle due to the small number of years taken, but overall, England and Wales have a more uniform distribution. Data is from http://github.com/fivethirtyeight/data/tree/master/births and http://ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/livebirths/articles/howpopularisyourbirthday/2015-12-18 . In the SVG file, hover over a date to highlight it on both tables."

This does at least go some way to answer the Qs re sources - perhaps a Wikipedian slciker at edits than myself could incorporate this into the main article?

The sources for the heat map can be found here: https://commons.wikimedia.org/wiki/File:Most_common_birthdays.svg Some1 (talk) 11:52, 4 April 2023 (UTC)[reply]

Thanks - our posts overlapped.

When I click on the image however, I do not reach that Commons page with the metadata readable. MrEckLeckTick (talk) 11:55, 4 April 2023 (UTC)[reply]

I had to click the little icon to the top right of the caption to get to https://en.wikipedia.org/wiki/File:Most_common_birthdays.svg. I'm not sure why clicking on the image itself doesn't take readers to the File page. Cmglee, could you help answer? Thanks! Some1 (talk) 12:07, 4 April 2023 (UTC)[reply]

@Some1, The link parameter was set to point directly at the SVG file so that the reader can use its interactivity: highlighting the entire column and rows (in both regions) of the cell pointed at. As you found, the file page can still be accessed with the

icon. This is a workaround while http://phabricator.wikimedia.org/T5593 is being resolved. Cheers, cmɢʟee⎆τaʟκ 12:51, 4 April 2023 (UTC)[reply]

@MrEckLeckTick: Thanks for finding and reposting the info. I quite agree that the footnotes and references should be in the caption, and can add them if we all concur here. Cheers, cmɢʟee⎆τaʟκ 12:56, 4 April 2023 (UTC)[reply]

The interactivity of the heatmap is a key feature, so it's important that is preserved. You adding the footnotes and refs into a caption sounds a good plan to me. Be aware that the gobbet I quoted above is missing the correct symbols for the asterisk, dagger and double dagger, so better to use the text from the metadata page on Wikipedia Commons.

Thanks for offering to sort it - the article will definitely benefit.

Cheers,

MrEckLeckTick MrEckLeckTick (talk) 18:16, 4 April 2023 (UTC)[reply]

Cmglee, yes, that sounds like a good idea to me too. Feel free to make the edit. Some1 (talk) 23:44, 4 April 2023 (UTC)[reply]

I've decided to add a link to the description on the file page instead of cluttering the caption with a legend and pushing down the wide graph on narrow browsers, creating an unsightly gap between it and its heading. How's that? cmɢʟee⎆τaʟκ 03:17, 5 April 2023 (UTC)[reply]

Graph of rankings

I wonder if anyone else finds File:Graphic_birthday_rank_USA.svg possibly misleading:

Graph of rankings

Unless one pays attention to the caption and vertical axis, it looks like a frequency distribution.

It makes all relative differences uniform, so the first-place bar is longer than the second-place bar by the same amount as any two adjacent ranks, where the differences in frequency is extremely unlikely to be so.
Comparing absolute lengths, the first-place bar is 1/365 longer than the second-place bar, but the penultimate-place bar is twice longer than the last-place bar.

Plotting frequencies seems more representative of reality to me.

Nevertheless, as with the table version, the number of years is too small (or at least, the occurences of, say, Jan 1 is not distributed evenly over the days of the week) such that the weekly spikes are apparent, making it hard to discriminate effects of day-of-week from day-of-year.

Cheers,
cmɢʟee⎆τaʟκ 03:35, 5 April 2023 (UTC)[reply]

Yes, I find it very misleading. I wrote a little about it here. I realize now that it was probably the wrong place. A frequency plot (per day of year) with enough data would be much more appropriate, perhaps combined with an illustration of the day-of-week distribution. I also understand that there are significant variations between countries, which is not apparent now. 98.128.246.117 (talk) 07:52, 20 July 2023 (UTC)[reply]

P.S. As we have data for 1995 to 2014, can we restrict the choice of years to distribute each day-of-year uniformly over each day-of-week? It gets complicated with leap years, though. Cheers, cmɢʟee⎆τaʟκ 03:58, 5 April 2023 (UTC)[reply]
