Based on this page from the French School for Advanced Studies in the Social Sciences, it appears that the neighbouring Balsesmes merged into La Haye-Descartes in 1966, before the combined commune was renamed to Descartes the next year.
In 1962, the two communes had remarkably similar population levels of 1,679 and 1,689. With a combined population of 4,267 ...

Not really.
Generally speaking, most European women since married in their early to mid twenties, to men in their mid to late twenties. The age gap for the commoners, i.e. the vast majority of the population, were typically not large. Unfortunately the question declined to define how much younger is "much younger" supposed to mean, but most Europeans ...

There were two major, interrelated events that caused this population boom in the 1970s.
The first was the discovery of oil on Alaska's North Slope at Prudhoe Bay and elsewhere in 1968 and 1969. The second was the raising of oil prices by OPEC in 1973 and 1979. Both sets of developments resulted in the rapid growth of oil production in Alaska, and its ...

For the vast majority of Germans, religious and non-religious alike, religion matters little in daily life. In some families, the babies are baptised, marriages have both civil and religious ceremonies, and one goes to the service on Christmas and perhaps on Easter. Yet in a survey or opinion poll, these people might report themselves as Christian. This kind ...

I think you are missing the true pattern of that map. Note that it shows a higher percentage of natives in Canada than it does in the US, and shows the same lower percentage of natives in the USA as in a geographically contiguous area of South America (1% or less).
If anything, the real pattern there is that areas in the subtropics (but not subartic) have ...

I've combined the data in:
List of largest cities throughout history
World population estimates
The winners are:
Modern Tokyo (metropolitan area), home to 0.55% of the world's population
700 AD Chang'an, home to 0.44% of the world's population
200 AD Rome, home to 0.42% of the world's population
1 AD Rome, 400 AD Rome, and 1900 AD London follow, all ...

University of Alaska, Anchorage published a study into People and Economy of Alaska, which can be viewed here.
From that source, I'd say there are following reasons for their population boom:
Discovery of Oil
As Tom has already mentioned, Oil was discovered in 1968 in Prudhoe Bay oilfields. Alaska collected $55 billion in oil revenues through 2001, with ...

According to this article the ratio rose from 1.10 to about 1.54 (ratio of men/women fell from 0.91 to about 0.65) between 1941 and 1946 in the draft-age group (people born around 1887 to 1927), which was the most affected by the war losses.
Other age groups were less affected, so I'd say that the overall ratio would be around 1.3-1.25 (0.75-0.8 men/women)....

There's nothing really odd about this. The same thing historically has happened all over the globe any time an immunologically naïve population meets up with one that is tapped into all of the worldwide reservoirs of diseases. Eventually the native population can naturally select similar genetic protections to the ones the colonizers already had, but that ...

German here. You see here a chart of the predominant confessions in Germany:

As you see, approximately one third is Roman-Catholic (yellow), one third is Lutheran (violet, this is not the same church like in the USA despite having the same roots!) and the former German Democratic Republic ...

During the war the reason for the internal civilian migration was jobs fueled by war production. After the war people left the north east for the sunbelt, for jobs and with the increased use of air-conditioning the sun-belt became a much more attractive / comfortable option.
WW2 Years
17 Million new good paying civilian jobs were created across the ...

Apart from other reasons here exposed, I think it is worth mentioning
a) some groups of South American natives were adapted (culturally, and even in some cases, physically) to environments which were not comfortable for white settlers. For extreme examples, think of Amazonian tribes and inhabitants from the Andean Plateau. In these cases, there was little ...

The Soviet population in 1941 was 196,716,000. In 1946, it was 170,548,000.[1] That's a difference of 26,168,000 people. According to a study published by the Russian Academy of Science[2], there were 12,300,000 births and 11,900,000 natural deaths during war, so the populational decrease must be entirely attributed to war deaths. Considering 400,000 births ...

Expanding on @MonsterTruck's comment above, China (especially the east part) is really good for food production. According to Wikipedia's list of countries by agricultural output China has 17 per cent of global agricultural production today, compared to around 7 for the European Union, 7 for India and 4 for the United States. I would expect the construction ...

UPDATE: Aaron Fogleman estimates that 585,000 people "immigrated" (many involuntarily) to the 13 colonies between 1700-1775. If they all survived until the time of the Revolution, then 24% of the population at the time of the Revolution would be foreign born (585,000/2,400,000 = .244). Of course this is an absurd assumption, so treat this estimate as an ...

Actuarial science was just getting started in the 17th century, so we can answer this question with some specificity--for London and Breslow, anyway.
John Graunt made the following life table for London in 1662 (source):
Around 1% of Londoners were older than 77.
Edmond Halley (of comet fame) made the following table for Breslau in 1693. Note that births (...

The oldest human could still live to be over 100 just as they do today. This was of course much rarer. Here's some data from the University of Texas on the matter. Infant Mortality by that page was 31.9% considerably worse than even the worst of the world 60 years ago. This was skewed by infanticide and such.

As far as we can tell, Medieval French families were significantly bigger than modern western families - averaging perhaps around five to six. In contrast, modern France has an average household size of 2.38. However, they remained relatively small scale, and somewhat nuclear families of mostly two generations. Note the standard disclaimers apply: pre-modern ...

Question : Are there good analyses of this remarkable population decline that go beyond simple explanations like "diseases"?
I was going to just leave a comment, but decided against it to heed – Mark C. Wallace's policy reminder above.
As @T.E.D. stated in his fine answer, the pattern is common. It occurred in South, Central and North America; as well as ...

Pre-columbian population of North America was only a couple of million people, most of them are pre-agricultural hunter-gatherers. This kind of lifestyle does not allow more than 2-4 million people people to live on the continent. Central and South America, on the other hand, was home of several large civilizations with developed agriculture, and ...

A recent report by USAID offers a brief but insightful view on some of current research on 'Youth Bulge' hypothesis. Some of the key take-away are:
The common thread across the latest research is that youth bulges alone do not cause conflict. Rather, when unstable politics and social deterioration are combined with large numbers of disadvantaged young men, ...

Because people are quibbling in comments over the meaning of "overpopulation", it might suggest that this question is broad or unclear. So let's look at it from a different angle.
In the 1960's, Dr. John Calhoun, working at NIH, conducted his famous (some would say infamous) "mouse utopia experiment".
Mice were placed in an enclosure (named "Universe 25") ...

Using the delta areas as proxies for the entire river valley systems:
The area of the Ganges delta (about 59,000 km^2) is nearly 4 times as large as Mesopotamia (about 15,000 km^2), and 3 times as large as the Nile river delta (about 19,000 km^2). Additionally:
Once wet-rice cultivation with paddies is developed, rice provides nearly twice the calories per ...

The history is disputed between the Rakhine and Rohingya, but in essence it is related to population movement between the Chittagong region (now south-eastern Bangladesh) and Arakan (now Rakhine state in Burma/Myanmar), and so whether the Rohingya should be seen as recent immigrants or as indigenous people. Most Rakhine, Burmese and Buddhists from other ...

In the end of the XIX century most Jews were concentrated in the Russian empire.
(Modern Poland, Ukraine, Belorussia). Until 1917 Jews in the Russian empire
were discriminated (Pale of settlement, restrictions on education, discrimination in the army etc.). There were pogroms,
people were killed, their property destroyed. With the start of WW I, conditions ...

Quite apart from Semaphore's assertion that there simply were more Amerindians in the south than in the north, there's also the factor that there was far more immigration of Europeans and Asians into the north than there was into the south.
But that's not all of it. Another important factor is how the numbers are established.
Especially in the US people who'...

From IPUMS (click on "case count" here) we have the number of farm and nonfarm households in the United States from 1850 onwards (note comparability problems after 1950). In their 1% sample of the 1850 census, more than half of households are non-farm. However, the groups are close to equal size, so we can expect the equal split (in households) to have taken ...

From the US Census, 1920 was the first census where more than half the population was considered Urban rather than Rural. This might be considered a rough answer to your question.
