With the triumph of Justin Trudeau (#1) in the Canadian federal election (#13), he also placed top in our chart this week, though some of this Internet popularity appears to be due to his "hotness". This also placed his father and former Canadian prime minister Pierre Trudeau at #4. And with "Back to the Future Day" falling on October 21, Canadian-American actor Michael J. Fox landed at #3. Thus, three of the top five spots this week, and seven of the Top 25 (beating the five placed by India in July), are Canada-related. As the 37th most populated country in the world, this seems a feat unlikely to soon be repeated.

Elsewhere on the chart, the coming of Star Wars: The Force Awakens, which still doesn't happen until December, took up two slots in the Top 10. A new age-titled album from singer Adele placed #7, and the Top 10 was rounded out by a Reddit thread about a rare disease, and the stalwart Deaths in 2015.

For the week of October 18 to 24, 2015, the ten most popular articles on Wikipedia, as determined from the report of the most viewed pages, were:

Rank	Article	Class	Views	Image	Notes
1	Justin Trudeau		2,709,956		Trudeau is expected to soon take over as Prime Minister of Canada following the success of his Liberal Party in the recent Canadian federal election. Trudeau's father Pierre Trudeau (#4) served in that role from 1968-1984 (with a brief break in 1979-80). With over 2.7 million views for the week, this was quite a popular event. To some unknown extent, the article's views were inflated by widespread press coverage about the subject's attractiveness, both pro and con.
2	Star Wars: The Force Awakens		1,271,270		If you've caught the press coverage about this upcoming movie here and there, you may be asking yourself, is this thing ever coming out? A poster and new trailer was released last week, which apparently caused a frenzy on the part of the internet not ogling the force of Justin Trudeau. And for those us not that closely involved, the answer is that it rolls out in parts of Europe on December 16, the U.K. on December 17, and North America on December 18.
3	Michael J. Fox		933,448		October 21, 2015 was "Back to the Future Day" – the day in the future that Marty McFly (played by Fox) traveled to in the 1989 film Back to the Future Part II. And though we don't have true hoverboards or a Jaws 19 movie, and the Chicago Cubs just missed their chance to make it to the World Series, the Internet nostalgia engine was running out of control. And with fathers and son Trudeau, the appearance of the Canadian born Fox means that Canada, the 37th most populated country in the world, has placed three of the top five articles this week, a feat unlikely to ever be repeated.
4	Pierre Trudeau		860,884		Ranked by scholars as one of the greatest Canadian prime minsters, and also the slightly less attractive forebear of this week's #1.
5	Back to the Future		767,683		See #3, # 11, and #15.
6	Black hole		612,175		Up from #13 last week, but a debatable entry. The first entry without 1970/80s roots, as the 1979 Disney film The Black Hole simply does not generate that much warm nostalgia. Though a Reddit thread could lift an article like this into the Top 10 on any given week, we do not see any such thread. Stats.grok.se shows a jump in views starting on October 13 from a few thousand per day to over 40,000 per day. It has 25% mobile views (not the either 0% or 99% typical of bot-view popularity), but we may drop this from the list if these steady views continue and a human-based explanation cannot be found.
7	Adele		581,472		The popular singer's new album 25 will be released on November 20. The first single, "Hello", debuted on October 23. As of this writing, the video for "Hello" already has 73 million views.
8	Star Wars		567,518		See #2.
9	Fibrodysplasia ossificans progressiva		545,423		October 24 saw the most interest in this article, generated by a Reddit thread that stated "[today I learned] that there is a disease that makes the body repair injuries using bone, over the course of many years, this leads to the victim becoming more and more like a statue." Non-sensational headlines like this actually can get attention on Reddit; they don't need to use clickbait thread titles like "Feeling lethargic today? Find out if rare disease may be turning you into stone!"
10	Deaths in 2015		535,526		The viewing figures for this article have been remarkably constant; fluctuating week to week between 450 and 550 thousand on average, apparently heedless of who actually died. Deaths this week included NASA specialist Robert W. Farquhar whose projects included the first probe to intercept a comet in 1985 (October 18); Miss Austria 2013 Ena Kadić, who died from injuries sustained from falling off a mountain (October 19); Polish-Austrian economist Kazimierz Łaski, a leading proponent of Post-Keynesian economics (October 20, pictured); Pakistani cricket manager Yawar Saeed (October 21); Former Mexican senator Tomás Torres Mercado, who died in a plane crash (October 22); Croatian chess grandmaster Krunoslav Hulak (October 23); and 20-year-old British charity fundraiser Kirsty Howard (October 24).
